Ghd7 is a gene controlling rice grain number per panicle,plant height,heading stage,and the main effect of QTL.
Grain Number, Plant Height, and Heading Date7（Ghd7） Is a Central Regulator of Growth, Development, and Stress Response in rice
Function
In long sunshine condition, the enhanced expression of Ghd7 could delay the earing, increase the plant height and grain number per panicle, and the natural mutant with weaken function can grow to temperate and even colder regions. Ghd7, therefore, has a very important role for an potential increase and adaptability in global rice yield . PhyA alone or phyB and phyC work together can induce Ghd7 mRNA accumulation, and phyB alone can reduce the Ghd7 mRNA level to some degree. In addition phyB and phyA can influence the actiity of the Ghd7 and Hd1 respectively. Hd2 and Hd16, Hd2 and genetic interactions between Ghd7. Hd2 and its genetic interactions has a very important role for heading stage by controlling the condition of long sunshine.
Grain number, plant height, and heading date7 (Ghd7) has been regarded as an important regulator of heading date and yield potential in rice;As a long-day dependent negative regulator of heading date, the degree of phenotypic effect of Ghd7 on heading date and yield traits is quantitatively related to the transcript level and is also influenced by both environmental conditions and genetic backgrounds. Ghd7 regulates yield traits through modulating panicle branching independent of heading date. Ghd7 also regulates plasticity of tiller branching by mediating the PHYTOCHROME B-TEOSINTE BRANCHED1 pathway;so,Ghd7 functions to integrate the dynamic environmental inputs with phase transition, architecture regulation, and stress response to maximize the reproductive success of the rice plantCite error: Closing </ref> missing for <ref> tag
