摘要:
海藻糖酶(trehalase,Tre)是昆虫体内海藻糖代谢的关键酶,在生长发育与能量调节中扮演重要角色。为克隆春尺蠖(Apocheima cinerarius)海藻糖酶基因,分析其序列特征及系统进化关系,同时对其在不同饥饿处理时间下的表达水平进行分析,明确海藻糖酶基因在春尺蠖应对饥饿胁迫中的作用,基于春尺蠖4龄幼虫转录组数据,结合RT-PCR技术克隆春尺蠖TreTre-like基因,分析其氨基酸的理化性质,同时分析序列一致性及系统进化关系。克隆获取春尺蠖2条可溶性TreTre-like基因,分别命名为AcinTre1A和AcinTre1A-like,预测分子式分别为C3 122H4 716N806O934S16和C3 037H4 620N800O856S14,CDS全长分别为1 803、1 746 bp,分别编码601、582个氨基酸,蛋白的预测分子量分别为68.99、66.48 ku,理论预测等电点分别为4.95、6.08;AcinTre1A为不稳定亲水蛋白,而AcinTre1-like为稳定亲水蛋白;编码蛋白均具有海藻糖酶超家族保守结构域、信号肽,但无跨膜结构;磷酸位点检测在AcinTre1A与AcinTre1A-like中分别发现丝氨酸26、22个,苏氨酸16、11个,酪氨酸13、15个;均发现1个糖基化位点。序列一致性分析表明,春尺蠖AcinTre1A与灰斑霜尺蠖Apocheima pilosaria的一致性最高,为88.54%,AcinTre1A-like与烟草天蛾Manduca sexta的一致性为79.21%;系统进化结果表明,AcinTre1A和AcinTre1A-like分别聚在2个分支上;春尺蠖AcinTre1A与同为尺蛾科的灰斑霜尺蠖ApilTre1A聚为一类,AcinTre1A-like与天蛾科的烟草天蛾聚为一类;斜纹夜蛾Spodoptera litura与草地贪夜蛾Spodoptera frugiperda Tre-like基因在系统进化树中与其他昆虫的Tre更近。基因表达结果表明,随着饥饿处理时间的增加,AcinTre1A和AcinTre1A-like的表达量均呈现下降趋势,AcinTre1A-like下降速度较缓,AcinTre1A则下降较快;与对照相比,除6 h外,其余时间基因表达量均差异显著(P<0.05)。海藻糖酶基因在春尺蠖应对饥饿胁迫的响应中扮演重要角色。
