Abstract

Rice tiller angle, as a component of plant architecture, affects rice grain yield via plant density. However, the molecular mechanism underlying rice tiller angle remains elusive. We report that the key domestication gene PROSTRATE GROWTH 1(PROG1) controls rice tiller angle by regulating shoot gravitropism and LAZY1(LA1)-mediated asymmetric distribution of auxin. Acting as a transcriptional repressor, PROG1 negatively regulates the expression of LA1in light-grown rice seedlings. Overexpression of LA1partially rescued the larger tiller angle of the PROG1complementation transgenic plant (prog1-D).Double-mutant analysis showed that PROG1acts upstream of LA1to regulate shoot gravitropism and tiller angle. Mutation of Suppressors of lazy1(SOL1), encoding DWARF3 (D3) acting in the strigolactone signal pathway, suppressed the large tiller angle of prog1-Dby rescuing the transcription of LA1. The discovery of a light-sensitive PROG1-LA1transcription regulatory module controlling rice shoot gravitropism and tiller angle sheds light on the genetic control of rice tiller angle.
