Abstract
The role that the putative thylakoid lumenal cyclophilin (CYP) CYP20-2 locates in the thylakoid, and whether CYP20-2 is an essential gene, have not yet been elucidated. Here, we show that CYP20-2 is well conserved in several photosynthetic plants and that the transcript level of the rice OsCYP20-2 gene is highly regulated under abiotic stress. We found that ectopic expression of rice OsCYP20-2 in both tobacco and Arabidopsis confers enhanced tolerance to osmotic stress and extremely high light. Based on these results, we suggest that although the exact biochemical function of OsCYP20-2 in the thylakoid lumen (TL) remains unclear, it may be involved in photosynthetic acclimation to help plants cope with environmental stress; the OsCYP20-2 gene may be a candidate for enhancing multiple abiotic stress tolerance.
