The mechanism by which GAs promote shoot height has been studied extensively, but it is not known what causes the inverse relationship between plant height and tiller number. Short growth period is not the key limiting factor to late‐emerging tillers. D14–SCFD3-dependent degradation of D53 regulates strigolactone signalling. Comparative transcriptome analyses reveal different mechanism of high- and low-tillering genotypes controlling tiller growth in orchardgrass (Dactylis glomerata L.). 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. Thus, it is necessary to optimize the tiller number to achieve the maximum yield in rice. A tiller number is the key determinant of rice plant architecture and panicle number and consequently controls grain yield. The Rice Circadian Clock Regulates Tiller Growth and Panicle Development Through Strigolactone Signaling and Sugar Sensing. To increase levels of free IAA, we treated rice plants with three different concentrations of exogenous IAA (1 μM, 10 μM and 100 μM) twice a week by spraying. 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).

Plant Cell Physiol. Genetic regulation of shoot architecture. Plant Signaling & Behavior: Vol. Tiller number and spikelet fertility (seed set) are two critical traits that define grain yield in rice. The tiller develops from an axillary bud which dif­ ferentiated on an axil of a leaf of rice plants. Excessive tillering can lead to reduced grain yield because the tillers compete for resources with the main shoot and in turn impair fertility. Our results suggested that OsNPF7.2 is a positive regulator of nitrate influx and concentration, and that it also regulates cell division in tiller bud and alters expression of genes involved in cytokinin and strigolactone pathways, resulting in the control over rice tiller number. found that nitrogen fertilizer application increased the number of rice tillers, but not every tiller contributed equally to the overall yield. The tillers having filled grains were recorded as effective tillers and the tillers without filled grains were recorded as non-effective tillers. This discovery provides a molecular explanation for the coordinated control of plant height and tiller number in rice by GAs, SLR1 and MOC1. Development. increasing japonica rice tiller number is urgent for breed-ing programs to produce japonica cultivars with high yield and good grain quality. GAs trigger the degradation of SLR1, leading to stem elongation and also to the degradation of MOC1, and hence a decrease in tiller number.
