Under different nitrate concentrations, tiller buds grew faster in OX lines than in WT, but they grew slower in Ri lines and mutant osnpf7.2.  |  The number of effective tillers per m 2 was calculated for each plot just before harvesting the crop. Plant Signaling & Behavior: Vol. Wu Z, Tang D, Liu K, Miao C, Zhuo X, Li Y, Tan X, Sun M, Luo Q, Cheng Z. J Exp Bot. Since elevated expression of OsNPF7.2 is capable of improving rice grain yield, this gene might be applied to high-yield rice breeding. doi: 10.1093/pcp/pcp091. 2007 Oct;10(5):461-5. doi: 10.1016/j.pbi.2007.08.011. The breeding of cereals with altered gibberellin (GA) signaling propelled the 'Green Revolution' by generating semidwarf plants with increased tiller number. A tiller number is the key determinant of rice plant architecture and panicle number and consequently controls grain yield. A tiller number is the key determinant of rice plant architecture and panicle number and consequently controls grain yield. Huang W, Bai G, Wang J, Zhu W, Zeng Q, Lu K, Sun S, Fang Z. NIH Tillering is an important agronomic trait for rice population quality and grain production. 23 Tiller Number Hill : Rice varieties showed significantly levels were P = Control (Without phosphorus), P = 24 Kg differences for tiller production which ranged between 01 P O ha 2 5 2,P = 48 Kg P O ha 25 3 ,P = 72 Kg P O ha 25 and 4.60 and 20.51 (Table 1). doi: 10.1007/s00299-008-0665-z. Epub 2007 Sep 27. The tiller develops from an axillary bud which dif­ ferentiated on an axil of a leaf of rice plants. Rice is one of the three major crop species that provide food for more than half of the global population.

After … The levels of gene transcripts related to cytokinin pathway and cell cycle in tiller bud, and cytokinins concentration in tiller basal portion were higher in OX lines than that in WT, suggesting that altered expression of OsNPF7.2 controlled tiller bud growth and root development by regulating cytokinins content and cell cycle in plant cells. Front Genet. Tiller number is an important agronomic trait that plays a role in rice yield by influencing the number of panicles per plant [1]. Please enable it to take advantage of the complete set of features! Altered expression of OsNPF7.2 regulated CKs concentration and cell cycle. Thus, it is necessary to optimize the tiller number to achieve the maximum yield in rice. a Expression level…, Expression of genes involved in strigolactone biosynthesis, perception and signalling pathway. 2002;99:9043–9048. (2020). AbstractAppropriate plant height, tiller number and heading date are important traits for maximizing rice production. The hierarchy in tiller development becomes evident as grain yield becomes poorer in each successive tiller [ 20 , 21 ]. The amino acid transporter AAP1 mediates growth and grain yield by regulating neutral amino acid uptake and reallocation in Oryza sativa. OsNPF7.2 OX lines showed more significantly enhanced influx of nitrate and had a higher nitrate concentration than WT. Rice (N Y). The rice d27 mutant is a classic rice mutant described previously (Ishikawa et al., 2005; Arite et al., 2007).To elucidate the molecular mechanism that determines rice tiller number, we further characterized d27 in depth. For the same types of rice tillers, the number of LVB or SVB was significantly affected by N rates (P = 0.002); however, the differences caused by N treatment were lower than those caused by the tiller type (P … 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 COVID-19 is an emerging, rapidly evolving situation.

Overexpression of OsMYB305 in Rice Enhances the Nitrogen Uptake Under Low-Nitrogen Condition. Despite their differences in bud initiation time, the main shoot and all tillers grow to a uniform height and flower at the same time [1]. Rice tiller number is one of the most important factors that determine grain yield, while nitrogen is essential for the crop growth and development, especially for tiller formation.

This discovery provides a molecular explanation for the coordinated control of plant height and tiller number in rice by GAs, SLR1 and MOC1.

In direct-seeded rice fields with a normal plant population (10 to 20 plants per square foot), rice plants generally produce two to five panicle-bearing tillers per plant compared to 10 to 30 tillers per plant in transplanted rice where more space is available between plants.

Our analyses showed that rice tiller number and grain yield were significantly increased in OX lines, whereas Ri lines and mutant osnpf7.2 had fewer tiller number and lower grain yield. The tillering capacity of rice plants varies with variety, plant spacing, fertility, weed competition and damage from pests. Plant Physiol.

Overexpressed glutamine synthetase gene modifies nitrogen metabolism and abiotic stress responses in rice. However, comprehensive analyses of the genetic basis of the tiller number, considering the development stage, tiller type, and related traits, are lacking. In direct-seeded rice fields with a normal plant population (10 to 20 plants per square foot), rice plants generally produce 2 to 5 panicle bearing tillers per plant compared to 10 to 30 tillers per plant in transplanted rice where more space is available between plants. Release of the repressive activity of rice DELLA protein SLR1 by gibberellin does not require SLR1 degradation in the gid2 mutant.
