摘要:
分析家蚕δ-鸟氨酸转氨酶基因Bmoat序列信息,明确其组织转录规律,结合家蚕感染BmNPV对其表达的影响,初步探索该基因功能。克隆家蚕δ-鸟氨酸转氨酶基因Bmoat ORF序列,对该基因编码区的氨基酸序列、分子量、结构域等进行生物信息学分析;利用GeneDoc与MEGA 5.0软件对BmOAT与其他物种δ-鸟氨酸转氨酶进行多序列比对和系统进化分析;利用半定量RT-PCR对其组织和时期转录情况进行分析;实时荧光定量PCR检测家蚕添食BmNPV后Bmoat的表达情况。Bmoat编码407个氨基酸,属非分泌型蛋白,预测分子量为44.7 ku,等电点为 6.36。氨基酸序列同源性比较发现,BmOAT与棉铃虫转氨酶同源性最高,为84.3%。组织和时期转录特征分析表明,该基因在家蚕幼虫的各个组织均表达,且在家蚕整个幼虫时期持续性表达。Bmoat在家蚕感染BmNPV 3 h表达量基因明显上调,而在12、24 h呈现下调,表明Bmoat的表达受到BmNPV感染的诱导。家蚕δ-鸟氨酸转氨酶Bmoat在家蚕感染BmNPV后发生响应,推测该基因参与家蚕免疫应答,进而形成一定的机体能量补偿机制。
