OsCBL1 modulates lateral root elongation in rice via affecting endogenous indole-3-acetic acid biosynthesis.

Root growth is important for plants to efficiently acquire water and mineral nutrients from soil.Root system architecture(RSA),which is determined mainly by root branching through lateral root formation and root angles,has a significant influence on root growth.Generally,the growth and development of roots are regulated by numerous plant hormones,which respond to external environmental stimulation through com-
