摘      要：Long-term moderately high or low temperatures can damage economically important *** the present study,we treated Panax notoginseng,an important traditional Chinese medicine,with temperatures of 10,20,and 30℃for 30 *** then investigated *** glycerolipidome responses to these moderate temperature stresses using an ESI/MS-MS-based lipidomic *** long-term chilling(LTC,10℃)and long-term heat(LTH,30℃)decreased photo pigment levels and photosynthetic ***-induced degradation of photo pigments and glycerolipids may further cause the decline of photosynthesis and thereafter the senescence of ***-induced photosynthesis decline is attributed to the degradation of photo synthetic pigments rather than the degradation of chloroplastidic *** has an especially high level of lysophosphatidylglycerol,which may indicate that either *** phospholipase A acts in a special manner on phosphatidylglycerol(PG),or that phospholipase B *** ratio of sulfoquinovosyldiacylglycerol(SQDG)to PG increased significantly after LTC treatment,which may indicate that SQDG partially substitutes for *** LTC treatment,the increase in the degree of unsaturation of plastidic lipids was less than that of extraplastidic lipids,and the increase in the unsaturation of PG was the largest among the ten lipid classes *** results indicate that increasing the level of unsaturated PG may play a special role in maintaining the function and stability of *** photosystems after LTC treatment.
