利用蛋白质组学和荧光定量PCR方法,研究双孢蘑菇(Agaricus bisporus Lange(Imbach))02菌株在常温与高温胁迫下的蛋白质表达差异,发现了6个差异蛋白质点,经NCBI数据库比对分析,表明6个差异蛋白质分别为HSP7b家族的HSS1热激蛋白、异柠檬酸裂解酶、细胞色素P450单氧化酶及3个未知蛋白质.这些蛋白质在双孢蘑菇受热胁迫下具有保护自身稳定的功能.
Agaricus bisporus is a kind of cultivated edible mushroom which has high economic value and important ecology significance. Environment temperature is the main restrained factor in its development, and this greatly limits its cultivation season. In this study,2D-eletrophoresis and real-time PCR are employed to discover the proteomic difference in Agaricus bisporus 02 strain after high temperature induction, and 6 differential expressed protein spots were finally obtained. Compared with the NCBI data base , spot 1 is the heat shock protein ,spot 2 is isocitrate lyase and spot 3 is cytochrome P450 monooxygenase. The other three spots are novel. Presumably,those proteins confer the thermotolerance on strain 02 under high temperature.
