Proteomic identification of OsCYP2, a rice cyclophilin that confers salt tolerance in rice ( Oryza sativa L.) seedlings when overexpressed

Background High Salinity is a major environmental stress influencing growth and development of rice. Comparative proteomic analysis of hybrid rice shoot proteins from Shanyou 10 seedlings, a salt-tolerant hybrid variety, and Liangyoupeijiu seedlings, a salt-sensitive hybrid variety, was performed to identify new components involved in salt-stress signaling.
