摘要：	Ets蛋白是宿主MAPK信号通路下游的一类可参与调控病毒基因转录复制的重要转录因子。本研究通过基因克隆成功获得魁蚶(Scapharca broughtonii) Ets家族9条基因(分别命名为ETS-1~ ETS-9)，开放阅读框(ORF)大小分别为1065、1290、1569、912、1344、1404、1521、1968和1191 bp，并分别编码354、429、522、303、447、468、506、655和396个氨基酸。系统进化树分类表明，本研究所获得的基因均属Ets家族。对ETS-1和ETS-3的氨基酸序列和三维结构分析表明，其均含有高度保守的ETS结构域。在不同水温条件下，通过人工注射牡蛎疱疹病毒(OsHV-1)对魁蚶进行感染，并对病毒拷贝数和Ets的相对表达量进行定量分析。结果显示，ETS-1和ETS-3只在高温阳性组中相对表达量显著上调，与病毒拷贝数在高温条件下增长趋势呈正相关；ETS-4和ETS-8只在低温阳性组中相对表达量显著上调，但在高温阳性组中ETS-4和ETS-8的相对表达量与病毒拷贝数呈负相关；初步研究结果显示，从魁蚶Ets基因中筛选出2条Ets基因(ETS-1和ETS-3)，在高温条件下(16±2)℃，其可能参与正向调控病毒OsHV-1的复制过程。本研究为进一步探索魁蚶在夏季因感染牡蛎疱疹病毒(OsHV-1)而导致的大量死亡提供了科学数据。
