The growth and leaf area of WB was larger than GB. During vegetative growth, net assimilation ratio (NAR) was low, and increased during reproductive growth.
Compared with parental rice, LF rice showed an advantage in its vegetative growth and the yields of leaf, sheath and stem increased by 27.77%, 30.19% and 37.96% respectively.
The expression pattern and mutant phenotype suggest that the PLA1 gene acting in developing leaf primordia affects the timing of successive leaf initiation and the termination of vegetative growth.
