The molecular regulation mechanism between the high rice plant and the leaf angle has progressed.

The high rice strain and leaf angle are important aspects of the ideal strain pattern.
in the gritting period, upright leaves can make rice plants receive more light energy and increase yield, so molecular design of strains is an important strategy for rice breeding.
scholars at home and abroad have made some progress in the field of rice strain regulation, but there are still many scientific questions to be answered.
the study team of the Institute of Botany of the Chinese Academy of Sciences found that when OsmiR396d was overexpressed, the rice showed a phenotype of increased leaf angle and partial dwarfing.
researchers further through physiological testing, biochemical verification and genetic observation, confirmed that the core component of the canola ester signaling pathway OsBZR1 directly activates the expression of the OsMIR396d gene, OsmiR396d controls the transcription of the target gene OsGRF4 and OsGRF6 respectively; OsmiR396d by inhibiting the expression of OsGRF6, resulting in the synthesis and signal of erythromycin are weakened, causing the rice part of dwarfing phenotype;
the study further clarifies that miR396d in rice regulates the molecular mechanism of rice strain height and leaf angle by the signaling pathway of erythromycin and rapeseed, which provides new data for understanding the fine regulation of rice strains by plant hormones.
