Abstract Cyclophilin (CYP) plays an important role in plant response to stress, and OsCYP2, one gene of cyclophlilin
family, is involved in auxin signal transduction and stress signaling in rice. However, the mechanism that OsCYP2
is involved in rice response to low temperature is still unclear. We identified a new OsCYP2 allelic mutant, lrl3,
with fewer lateral roots, and the differences in shoot height, primary root length and adventitious root length
increased with the growth process compared to the wild-type plant. Auxin signaling pathway was also affected
and became insensitive to gravity. The transgenic rice plants with over-expression of OsCYP2 were… More >
