tillering in rice

osti.gov journal article: radiation-induced mutant having less tillering in rice. Importantly, rac-GR24 also stimulated expression of Oryza sativa 9-CIS-EPOXYCAROTENOID DIOXYGENASE 1 (OsNCED1) through induction of Oryza sativa HOMEOBOX12 (OsHOX12), promoting ABA biosynthesis in shoot base. Auxin transportation accomplished by the auxin i… We use cookies to help provide and enhance our service and tailor content and ads. Rice is a unique perennial crop with an indeterminate tillering potential, and the actual tiller- ing number is easily influenced by nutrients availability, planting density and variety [14–16]. Tiller development is characterized by three stages, including (i) AXM initiation, (ii) bud development, and (iii) outgrowth of the axillary bud into a tiller. Abstract. Tiller induction occurred with multiple commercial PL sources from Tillering marks the end of the seedling stage. Nutrition can affect head rice and amylose content. These tillers emerge and branch out from the base of the plant. Tiller induction by PL occurred in a num-ber of rice cultivars which included high- and low-tillering varieties. Phyllochrons are periods (cycles) of plant growth in which one or more phytomers (units of tiller, leaf, and root) emerge from the plant's meristematic tissue. Meet Ryza, the talking rice plant! Functional analysis of auxin receptor OsTIR1/OsAFB family members in rice grain yield, tillering, plant height, root system, germination, and ... Our findings demonstrate similarities and specificities of auxin receptor TIR1/AFB proteins in rice, and could offer the opportunity to … 1.4 the rice plant has a remarkable ability to compensate for low stands. Each upper node bears a leaf and a bud, which can grow into a tiller. 1). The seedling stage starts right after the first root and shoot emerge, and lasts until just before the first tiller appears. The genes controlling tillering in rice encode proteins involved in phytohormone-associated regulatory mechanisms. and barley (Hordeum vulgareL. rice tillering process involves two developmental stages: the formation of axillary meristems in the leaf axils and their subsequent outgrowth (Hanada, 1993). It is a plant species specific version of the BBCH-scale. The internodes vary in length depending on variety and environmental conditions, but generally increase from the lower to upper part of the stem. tiller number, but the combination of P1. These authors contributed equally to this article. However, the emerging leaf should not be counted. Tillering in rice (Oryza sativa L.) is an important agronomic trait for grain production, and also a model system for the study of branching in monocotyledonous plants. Tillering in rice (Oryza sativa L.) is an important agronomic trait for grain production, and also a model system for the study of branching in monocotyledonous plants. If rice plants are spread out and not planted very close together, they have more room to … Temperate Japonica (TEJ) rice belongs to the northern ecotype in China, and subtropical indica (IND) rice belongs to the southern ecotype. Vegetative phasecovers the period from germination to panicle initiation, 2. The rice MOC1 gene, a putative GRAS family member, was found to control the Seedling stages occur during the first two to five weeks after planting. Different cultivation practices impact on tiller growth and development. This includes changes in growth direction, in shoot and root branching, and in vascular differentiation (Laskowski et al. 5. Tillering also depends on agricultural methods: the time and rate of sowing (early sowing usually causes greater tillering; in dense plantings there is less), seed quality (the larger the seed, the greater the tillering), depth of planting, and application of fertilizers. In addition, we discuss how the development of new genomics tools and approaches, coupled with the synteny between the rice and barley genomes, are accelerating the isolation of barley genes underlying tillering phenotypes. 1995, Leyser 2001, Paquette and Benfey 2001, Reinhardt et al. Who would know better about proper nutrition for rice than the rice plant itself? Tillering marks the end of the seedling stage. A tiller and its root start growing when the leaf from the third node above is emerging. High tillering capacity is a beneficial trait for grain production of rice, since the number of tillers per plant is closely related to the number of panicles per plant [58,59]. 2000). Auxin is thought to be synthesized in young apical tissues and then transported downward to the maturing stem and the roots by a polar transport system (Crozier et al. Several genes controlling rice tillering, which are regulated by poor N supply, have been identified. Tillering is a major determinant of rice plant architecture and grain yield. Rice (Oryza sativa L.) is one of the most important staple food crops in the world, and rice tillering and panicle branching are important traits determining grain yield. The low activity of SuSase and number of s… Here, we report that depletion of rice OsNRPD1a and OsNRPD1b, two orthologs of the largest subunit of RNA polymerase IV, leads to a high-tillering phenotype, in addition to dwarfism and smaller panicles. As stand density goes down, tillers per plant increase. The present study demonstrated that the number and contributions of late emerging tillers to rice grain yields were improved with increased N levels. Here we report a novel rice gene, Tillering and Dwarf 1 (TAD1), which encodes a co-activator of the anaphase-promoting complex (APC/C), a multi-subunit E3 ligase. The phytohormone auxin regulates a wide variety of developmental processes of plant growth. n. Tillering is one of the important stages that can be most influenced by management practices. Uneven crop nutrition can lead to variation in tillering and tiller maturity across a field, resulting in highly variable grain moisture content at harvest. Rice plants require N during the tillering stage to ensure a sufficient number of panicles. The length of the mesocotyl varies with cultivars. Tillering Stage This stage begins with the emergence of the first tiller and ends at Panicle Initiation. The results showed that, spraying Spd on rice leaves at a concentration of 0.5 mM promoted the growth recovery of rice after drainage, such as green leaves, tillers, and aboveground dry mass. Maturity phase covers the period from flowering to complete maturity. The vegetative phase: During the vegetative phase, the plant goes through the following stages of development: germination–emergence, seedling growth, tillering and inter-node elongation (according t… Some varieties are intrinsically better at tillering than others, and these differences can make a variety more “plastic”, adapting better to thin or dense stands. As rice enters the 3- to 4-leaf stage, tiller (or stool) formation typically begins, initiating the tillering stages. Each tiller has the potential to produce a panicle; however, not all do. 126 2. The vegetative phase is characterized by the development of tillers and more leaves, and a gradual increase in plant height. Similar trend was noted in WITA-4 and FARO 44 rice varieties where the more tillers were produced on the crop, the more they compensated for the number of spikelets per spike because a high tillering rice plant tends to "feed" more than the low tillering one. Due to the agro-nomic importance of tillering in rice breeding, many rice tillering mutants have been reported. The critical time at active tillering for N application is typically about midway between 14 days after transplanting (DAT) or 21 days after sowing (DAS) and panicle initiation. Around one hundred rice TN genes have been identified, but dissecting the genetic architecture of rice TN variations remains difficult because of its complex trait and control by both major genes and quantitative trait loci (QTLs). The season is advancing and fields are starting to go into tillering. This study characterized a rice mutant, the most obvious phenotypes of which are high t illering, reduced h eight, and i nfertile s pikelets (named this1). PL (Eneji et al. However, the number of spikelets per panicle and grain filling of late emerging tillers were significantly lower than that of the main stem or early emerging tillers at all N levels. SeedlingEmergence occurs when the first internode, called the mesocotyl, has elongated and pushed the tip of the rice coleoptile (epiblast) through the soil surface. Plants in dense stands produce fewer tillers than plants in thin stands (Fig. The ten stages of rice development can be grouped in three larger phases: 1. Here, we identified a high-tillering mutant tillering20 (t20), which could be restored to the wild type by treatment with the strigolactone (SL) analog rac-GR24. Tillering is an important agronomic trait for rice population quality and grain production. Tillering is a key component of yield for major cere - als such as wheat, rice, barley, and rye (Secale cereale L.) (Sakamoto and Matsuoka, 2004; Sreenivasulu and Schnurbusch, 2012). and fertilizer results in a syner-gistic increase in early tillers. When soil moisture is low, grasses tend to develop more sparse and deep root systems (as opposed to dense, lateral systems). In direct-seeded rice fields with a normal plant population (10 to 20 plants per square foot), rice … This means that when the 4th leaf starts emerging (from the 4th node), the 1st node's tiller and root start growing. These emerge all through the vegetative growth phase, but stop when plants reach panicle initiation (the starting point of the reproductive phase). Tillers can also arise from upper nodes, but such tillers are produced late and are less productive (Li et al., 2003; Ishikawa et al., 2005). You are currently not signed in. The t20 mutant has reduced SL and ABA, raising the question of how SL and ABA biosynthesis is coordinated, and whether they have overlapping functions in tillering. 1. These tillers are called secondary tillers. The modern short- stat- ... high tillering tropical indicas to our relatively lower tillering calrose or japonica types. 1. Tillering and Panicle Initiation: Tales of Ryza -- The ABCs of proper nutrition for rice plants - Duration: 9:39. International Rice Research Institute 91,681 views 9:39 Analysis of rice mutants with altered tiller number has shown that hormones play a key role in regulating axillary bud … In rice, d27 mutant plants showed an increased tillering and severe dwarf phenotype at the mature stage (Lin et al., 2009). Copyright © 2020 Elsevier B.V. or its licensors or contributors. We discovered that rac-GR24 stimulated T20 expression and enhanced all-trans-β-carotene biosynthesis. Research in California has shown that to avoid the problems related with thin and dense stands, take full advantage of the tillering capacity of rice plants, and produce good yields, plant densities must be between 15 to 20 seedlings per square foot. In the following sections, we will summarize progress in the identiication and characterization of genes, hormones, and developmen-tal pathways underlying tillering in rice and barley. Additionally, we highlight the emergence of new genom- To investigate whether the growth conditions in the two regions affect rice tillering, we selected 10 rice accessions from the previously studied rice … Improvements in rice tillering and growth have previously been noted with the combination of manure and fertilizer. By continuing you agree to the use of cookies. Rice tillers are specialized branches arising from axillary buds, usually at basal nodes of the primary stem (culm) and each bears a panicle. tillering synonyms, tillering pronunciation, tillering translation, English dictionary definition of tillering. All of California varieties, however, have more than ad- Tillering is an important trait of cereal crops that optimizes plant architecture for maximum yield. Rice tiller is a specialized grain-bearing branch that is formed on the unelongated basal internode and grows independently of the mother stem (culm) by means of its own adventitious roots. In addition, we discuss how the development of new genomics tools and approaches, coupled with the synteny between the rice and barley genomes, are accelerating the isolation of barley genes underlying tillering phenotypes. Some tillers die before flowering because of shading by other tillers or weeds; the surviving tillers will produce a panicle. Intensified tillering, within certain limits, increases the harvest. The critical time at active tillering for N application is typically about midway between 14 days after transplanting (DAT) or 21 days after sowing (DAS) and panicle initiation. The MONOCULM 1 (MOC1) gene is the first identified key regulator controlling rice tiller number; however, the underlying mechanism remains to be elucidated. However, less is known about how nitrogen‐regulated rice tillering … Tillering in rice (Oryza sativa L.) is an important agronomic trait for grain production, and also a model system for the study of branching in monocotyledonous plants. OsWUS, an ortholog of Arabidopsis WUSCHEL (WUS) in rice, is required for tiller development. In dense stands, the duration of the tillering phase, and in turn, the maturity period for panicles, is reduced. Agriculture and Natural Resources, University of California. Rice tillering is an important agronomic trait for grain yield, but the mechanism underlying this process remains mostly unclear. If you have an account, then sign in now! Rice tillering, a key architecture trait determining grain yield, is highly regulated by a class of newly identi-fied phytohormones, strigolactones (SLs). Both nitrogen accumulation and tillering capacity were significantly influenced when the TD was varied from 5 seeds square-1to 125 seeds square-1. This ensures the formation of dense tufts and multiple seed heads. However, the whole SL signaling pathway from the receptor to downstream transcription factors to finally inhibit tillering remains unrevealed. For example, in a Butte County nitrogen by variety trial in … It starts when the fourth true leaf is fully emerged. However, the molecular mechanism associated with the regulation of tillering based on N supply is poorly understood. Since the gene MONOCULM 1 (MOC 1) was first characterized as a key regulator in controlling rice tillering and branching, great progress has been achieved in identifying important genes associated with grain yield, elucidating the … This period lasts from about 18 days after sowing to about 45 days after sowing. In contrast, rice cultivars such as Super Basmati, TN 1, Anakila and Agee displayed high tillering in combination with low production of the aforementioned strigolactones. Under low plant densities, more tillers are produced. These varieties induced only low S. hermonthica germination, attachment, emergence and dry biomass. Tillering rates are heavily influenced by soil water status. However, if stands are too dense, one runs the risk of disease and lodging. Late maturing varieties have longer periods of tillering than early maturing varieties. At this point, the main culm may be difficult to distinguish from the tiller. Rice tillering is an important agronomic trait affecting grain yield. After panicle initiation, tillers may continue to emerge from preexisting tillers, filling out the space among plants. I have always been amazed at the capacity of rice plants to adapt to the conditions of the field, producing more tillers in thin stands and less tillers in dense stands. To figure out whether spermidine (Spd) can alleviate oxidative damage on rice (Oryza sativa L.) caused by submergence stress, Ningjing 3 was used in this study. Rice tillers are specialized branches arising from axillary buds, usually at basal nodes of the primary stem (culm) and each bears a panicle… However, there were no conspicuous differences in plant height between the wild‐type and TaD27‐RNAi wheat plants (Figure 3g). Rice tiller number (TN) is one of the most important components associated with rice grain yield. This work demonstrates complex interactions in the biosynthesis of carotenoid, SLs and ABA, and reveals a role for ABA in the regulation of rice tillering. Tillers emerging in this way from nodes in the main culm are called primary tillers. The tillering ability of rice plants is seen in the number of phyllochrons of growth that they complete before entering their reproductive stage (Nemoto et al., 1995; Stoop et al., 2002). The degree of rice tillering is an important agronomic trait that can be markedly affected by nitrogen supply. Relationship between tillering and leaf area index: quantifying critical leaf area index for tillering in rice - Volume 138 Issue 3 - X. ZHONG, S. PENG, J. E. SHEEHY, R. M. VISPERAS, H. LIU Reproductive phase covers the period from panicle initiation to flowering, and 3. Tillering rates are heavily influenced by soil water status. In this review, we describe the genes and hormones that control tillering in two key cereal crops, rice and barley. Tillers are initiated at the base of the plant, emerging from the inside of the seedling leaves on the main shoot. The prophyll (first sheathing leaf) emerges through the coleoptile. Nutrients are transferred to the leaves by (xylem) tubes. Keywords: rice, submergence stress, exogenous spermidine, tillering stage, physiological characteristics Citation: Liu M, Chu M, Ding Y, Wang S, Liu Z, Tang S, Ding C and Li G (2015) Exogenous spermidine alleviates oxidative damage and reduce yield loss in rice submerged at tillering stage. Tillering in rice (Oryza sativa L.) is an important agronomic trait for grain production, and also a model system for the study of branching in monocotyledonous plants. When the 5th leaf emerges, the 2nd node's tiller and root start growing, and so on. GA negatively regulated expression of two transcription factors, O. sativa homeobox 1 and TEOSINTE BRANCHED1, which control meristem initiation and axillary bud outgrowth, respectively, and that in turn inhibited tillering. Tillering is a major determinant of grain yield of rice (Gallagher and Biscoe, 1978), and it is affected by environmental conditions (Yoshida et al ., 1981).The environmental effect on tillering was minimized by conducting this study in a greenhouse using hydroponic culture. Rice yield was highest and best maintained for years when farmyard Define tillering. Teosinte Branched 1 (TB1) is a negative regulator of lateral branching and an inducer of female inflorescence formation in Zea mays (maize). For rice plants to be more productive, they need to have: • More tillers per plant, • More fertile tillers (panicles) which form from the tillers that a plant puts out, • More grains per fertile tiller, and • Larger grains. In particular, rice overexpressing these GA2oxs exhibited early and increased tillering and adventitious root growth. At this stage, the nodes are all “compressed” close to the ground—the length between nodes (internode length) is less than 0.04 inches. It is not a true leaf because it lacks a leaf blade. This might be beneficial because it reduces the variability in maturity among panicles. The tillering capacity of rice plants varies with variety, plant spacing, fertility, weed competition and damage from pests. 2002) each significantly increased tillering in rice when added with fertilizer. Anonymous users messages may be delayed. In grasses like rice (Oryza sativaL.) This enables them to produce multiple stems (tillers) starting from the initial single seedling. Main food consumed, 2009: rice, fruits, vegetables, fish, meat, starchy roots, wheat, sugar and sweeteners Rice consumption, 2009-10: 123.3 kg milled rice per person per year Section Topics Because of their tillering capacity, plants can compensate for a thin stand by producing more tillers, and still reach high yields, as shown in Fig. At this stage, the nodes are all “compressed” close to the ground—the length between nodes (internode length) is less than 0.04 inches. Yields under thin or dense stands may not vary much. rice, barley, and wheat, allows the transfer of knowledge among these major crops. As rice enters the 3- to 4-leaf stage, tiller (or stool) formation typically begins, initiating the tillering stages. In a recent study published in AoB PLANTS, Wang et al. found that nitrogen fertilizer application increased the number of rice tillers, but not every tiller contributed equally to the overall yield. Tillers appear as secondary shoots to the main shoot. Below is a brief review of how the tillering process occurs and its implications for rice management. n. One that tills land: a tiller of soil. MaximumTillering – Tillering increases in a sigmoidal-shaped curve until the maximum tiller number is reached. Cumulatively, the inappropriate light distribution in PSII and the premature aging of flag leaves led to insufficient resources for late emerging tillers. Rice tiller is a specialized grain-bearing branch that is formed on the unelongated basal internode and grows independently of the mother stem (culm) by means of its own adventitious roots. Sacramento Valley Pest Management CE Webinar: December 9, SUPPRESS® Herbicide for use in Rice Weed Control, UCCE Sutter-Yuba-Colusa Continuing Education Series, Weed seed collection for herbicide resistance testing. Tillering in rice (Oryza sativa L.) is an important agronomic trait for grain production, and also a model system for the study of branching in monocotyledonous plants. T20 encodes a chloroplast ζ-carotene isomerase (Z-ISO), which is involved in the biosynthesis of carotenoids and their metabolites, SL and abscisic acid (ABA). However, rice tillering is developmentally controlled, and how it is regulated coordinately with reproductive growth remains unclear. Rice tiller is a specialized grain-bearing branch that is formed on the unelongated basal internode and grows independently of the mother stem (culm) by means of its own adventitious roots. Butte County, 1984-1985. 2000). "Tillering" refers to the production of side shoots and is a property possessed by many species in the family Poaceae. Relationship between plant stand, number of tillers per plant and yield. Tillering is a major determinant of grain yield of rice (Gallagher and Biscoe, 1978), and it is affected by environmental conditions (Yoshida et al ., 1981).The environmental effect on tillering was minimized by conducting this study in a greenhouse using hydroponic culture. This can result in a longer period of panicle maturity and a higher number of ineffective tillers (tillers that don't produce a panicle). On the other hand, ABA treatment significantly repressed SL biosynthesis and the ABA biosynthetic mutants displayed elevated SL biosynthesis. A critical step during rice (Oryza sativa) cultivation is dense planting: a wider tiller angle will increase leaf shade and decrease photosynthesis efficiency, whereas a narrower tiller angle makes for more efficient plant architecture.The molecular basis of tiller angle remains unknown. ABA treatment reduced the number of basal tillers in both t20 and wild-type plants. Rice tiller is a specialized grain-bearing branch that is formed on the unelongated basal internode and grows independently of the mother stem (culm) by means of its own adventitious roots. Furthermore, while ABA-deficient mutants aba1 and aba2 had the same number of basal tillers as wild type, they had more unproductive upper tillers at maturity. In this study, we identified and functionally characterized a low‐tillering mutant decreased culm number 1 ( dc1 ) that resulted from loss‐of‐function of OsWUS . Rice tillering has an important influence on grain yield, and is promoted by nitrogen (N) fertilizer. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. ζ-Carotene Isomerase Suppresses Tillering in Rice through the Coordinated Biosynthesis of Strigolactone and Abscisic Acid, https://doi.org/10.1016/j.molp.2020.10.001. trol tiller production will help us to breed new elite rice varieties to meet the continuing challenge of food production (Qian et al., 2016). The roots begin to extract nutrients from the soil. Published by the Molecular Plant Shanghai Editorial Office in association with Cell Press, an imprint of Elsevier Inc., on behalf of CSPB and IPPE, CAS. It starts when the fourth true leaf is fully emerged. ), vegetative AXMs form in the leaf axil of lower leaves of the plant and produce tillers (branches). The rice tiller is a specialized grain-bearing branch that normally arises from the axil of each leaf and grows independently of the mother stem (culm) with its own adventitious roots. The number of days the vegetative stage takes varies depending on the variety of rice, but is typically between 55 and 85 days.The early vegetative phase begins as soon as the seed germinates into a seedling and ends at tillering. Fig. 2001) and unidentified farmyard manure (Satyanarayana et al. Rice plants require N during the tillering stage to ensure a sufficient number of panicles. Tillering plants Each stem of rice is made up of a series of nodes and internodes. Thus, in dry soils, tillering is inhibited: the lateral nature of tillering is not supported by lateral root growth. Below is a brief review of how the tillering process occurs and its implications for rice management. Growth stage ... 2 Tillering or stem elongation may occur earlier than stage 13; in this case continue with stages 21 or 30 In theory, each node has the capacity to produce a leaf, a tiller and a root; however, tillers and their roots emerge later than leafs. aerobic rice - north china - water productivity - exploring options - modeling approach - less water - performance - emergence: Abstract: Water shortage in the Huai River Basin prompts farmers to adopt water-saving technologies such as direct-seeded nonflooded or aerobic rice. The BBCH-scale (rice) identifies the phenological development stages of rice Oryza sativa. In this review, we describe the genes and hormones that control tillering in two key cereal crops, rice and barley. Rice tiller is a specialized grain-bearing branch that is formed on the unelongated basal internode and grows independently of the mother stem (culm) by means of its own adventitious roots. Tillering potential and optimum tillering of rice Rice is cultivated mostly by seeds conventionally. Rice Growth and Development Introduction So you want to grow a 12,000 lb/acre rice crop.
