简介:温度是影响章鱼vulgaris的生长和幸存的一个重要环境因素,普通章鱼。理解保护的机制那O。在热应力下面的vulgaris展览,我们使用了cDNA结束(种族)的快速的扩大获得联系的三热压力回答的全身的序列基因:(1)热吃惊蛋白质70(OvHSP70),(2)热吃惊抄写因素(OvHSF),并且(3)O的热吃惊因素绑定蛋白质(OvHSBP)。vulgaris。OvHSP70,OvHSF,和OvHSBP蛋白质包含了2222bp,2264bp,分别地为635,458和90氨基酸编码了的841bp。多重顺序排列的结果证明OvHSP70的氨基酸序列高度关于另外的种类被保存。同样,DNA有约束力的域,OvHSF的trimerization域,和OvHSBP的卷的卷区域高度也保存了区域。即时聚合酶链反应(PCR)结果显示OvHSP70是温度依赖者和时间依赖者,显示积极回答加热应力。在到28敨慰潴慰据敲獡椠据敲獡摥猠杩楮楦慣瑮祬愠?桴?楦獲?的暴露上?栠愠摮?栠爠獥数瑣癩汥?椠摮捩瑡湩??楴獳敵?湡?楴敭搭灥湥敤瑮愠瑮潩楸慤瑮爠獥潰獮?湩?
