英文摘要	The cysteine protease gene MdCP2 plays an important role in responding to drought stress. In this study, the experimental materials were one-year-old M9T337' apple seedlings subjected to natural drought treatment. We determined the photosynthetic characteristics, plant water content, differentially expressed genes and the function of cysteine protease gene MdCP2 in leaves of apple seedlings during natural drought and rehydration process at physiological and molecular biological levels. The results showed that the photosynthetic rate, stomatal conductance and transpiration rate decreased under drought stress. In the later stage of natural drought, the major limiting factors of photosynthesis changed from stomatal restriction to non-stomatal restriction. The qRT-PCR results showed that MdCP2 had the higher expression level in roots and its expression had a significant positive correlation with the the degree of drought. The expression levels of MdRCA, MdCAB and MdRBCS were negative correlation with the degree of drought. Yeast two-hybrid and BiFC techniques were further used to demonstrate that MdCP2 interacts with MdGLK1. These results provide a theoretical basis for further study of cysteine protease MdCP2 gene.
