A point mutation in the zinc finger motif of RID1/EHD2/OsID1 protein leads to outstanding yield-related traits in japonica rice variety Wuyunjing 7.

ABSTRACT:

Background

Flowering time, which is often associated with the length of the growth period in rice, determines the adaptability of a plant to various environments. However, little is known about how flowering-time genes affect panicle development and yield formation potential in rice after inducing the transition from vegetative growth to reproductive growth.

Results

To explore the relationship between floral induction and yield formation and the molecular mechanism of panicle development in rice, a novel mutant, ghd10, was identified from japonica variety Wuyunjing 7 plants subjected to ethyl methane sulfonate (EMS) treatment. The ghd10 mutant exhibited delayed flowering time, tall stalks and increased panicle length and primary branch number. Map-based cloning revealed that
