The expression patterns of OsPIL11, one of six putative phytochromeinteracting factors(PIFs), were analyzed, revealing that expression of OsPIL11was organspecific and regulated by leaf development, ABA, JA and SA. To further explore the role of OsPIL11in plant light signal transduction, plant expression vector of OsPIL11was constructed and introduced into tobacco(Nicotiana tabacum). In continuous red light(R), OsPIL11overexpressed transgenic lines exhibited shorter hypocotyls and larger cotyledons and leaves compared to wildtype seedlings. While in continuous farred light(FR), either transgenic or wildtype seedlings showed similar phenotypes. These results indicated that OsPIL11was involved in Rinduced deetiolation, but not in FRinduced deetiolation in transgenic tobacco.
