英文摘要	Soil salinization threats the agricultural production and food security worldwide. Salt stress induced plant senescence and chloroplast degradation. However, it remains largely unknown how the chloroplast-localized proteins affect plant response to salt stress. Here, we characterized a novel gene (At5g39520) in Arabidopsis, which is induced by salt stress and encodes a chloroplast-localized protein. Thus, this gene was named SALT-INDUCED CHLOROPLAST PROTEIN (SCP). A T-DNA insertion mutant of SCP gene (scp-1) showed the enhanced tolerance to salt stress, as indicated by the increased survival rates, fresh weights and chlorophyll contents compared with wild type plants under salt treatment. Salt-induced leaf senescence was also delayed in scp-1 mutant. The scp-1 complementation line and SCP overexpression lines displayed the hypersensitivity to salt stress. The qRT-PCR analysis indicated that the transcripts of CHLOROPLAST VESICULATION (CV), which mediates stress-induced chloroplast degradation, were altered in scp-1 mutant and SCP overexpression lines. Taken together, our results suggest that SCP gene plays a negative role in response to salt stress and has potential application for genetic modification of improving plant tolerance to salt stress.
