text	PROSTRATE GROWTH 1 (PROG1) transcription factor plays a regulatory role in shoot gravitropism. It promotes tiller angle and tiller number in rice. Its action is opposite to LAZY1. LAZY1 represses PROG1 transcription by directly binding to the PROG1 promoter. Also, PROG1 acts as a repressor of the LAZY1 gene. These two genes play antagonistic roles in shaping plant architecture by regulating both tiller angle and tiller number (Wang et al., 2023).
