| 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 .
