Description OsPIN1, previously name REH1, is a putative auxin efflux carrier and a member of
PIN1 family, which is involved in auxin-dependent adventitious root emergence
and tillering in rice. OsPIN1 is expressed in the vascular tissues and root
primordial in a manner similar to AtPIN1 (At1g73590). Adventitious root
emergence and development were significantly inhibited in the OsPIN1 RNAi
mutants, which is similar to the phenotype of NPA (an auxin-transporter inhibitor)-
treated plants. Overexpression or suppression of the OsPIN1 resulted in the
changes of tiller numbers and shoot/root ratio. The decrease of adventitious
root numbers in OsPIN1 RNAi plants was caused by the arrest of the primordia
emergence.
