摘要:

【目的】蚜虫腹管是分泌防御性化学物质的重要组织器官,测序与分析腹管转录组,为蚜虫报警信息素合成与释放相关基因的鉴定提供分子基础。【方法】利用Illumina NoveSeq 6000测序平台对豌豆修尾蚜Megoura crassicauda腹管和残体进行转录组测序与比较分析,利用差异基因分析(Differential Expression Analysis,DEG)鉴定参与报警信息素合成与释放相关的候选基因,通过实时荧光定量PCR(Real-time Quantitative PCR,RT-qPCR)技术验证这些基因的表达模式。【结果】共鉴定出2 156个在腹管和残体之间存在显著差异表达的基因(表达差异≥2倍)。分析报警信息素合成相关的细胞色素P450(cytochrome P450 monooxygenase,CYP450)和萜烯合成酶(terpene synthase,TPS)基因家族。其中,3个CYP450s(McraCYP380CMcraCYP4CK1和McraCYP315A1)在腹管中的表达水平显著高于残体。而鉴定到的2个异戊烯基二磷酸合成酶(isoprenyl diphosphate synthase,IDS)基因,即法尼基焦磷酸合酶(farnesyl pyrophosphate synthase,FPPS)和香叶基焦磷酸合酶(geranyl pyrophosphate synthase,GPPS),在组织间的表达水平无显著差异。此外,分析报警信息素释放运输相关的潜在基因,鉴定到2个化学感觉蛋白(chemosensory proteins,CSP)基因在腹管高表达。McraCYP380CMcraCYP4CK1、McraCYP315A1以及McraCSP7基因在腹管中的表达水平显著上调。【结论】鉴定并分析了豌豆修尾蚜M. crassicauda腹管和残体转录组中的差异表达基因。

Abstract:

【Objective】 The cornicle of aphids is an important organ for secreting defensive chemicals. Cornicle transcriptome sequencing and analysis can provide molecular basis for identification of genes related to aphid alarm pheromone synthesis and release. 【Methods】 Transcriptome sequencing and comparative analysis were performed on the cornicles and residues of Megoura crassicauda using Illumina NoveSeq 6000 sequencing platform. The candidate genes were identified in the synthesis and release of alarm pheromones using analysis of the differentially expressed genes (DEGs), and the expression patterns of these genes were further verified by real-time Quantitative PCR (RT-qPCR). 【Results】 A total of 2156 genes were identified as DEGs between the cornicles and the residues (expression difference ≥2 times). Cytochrome P450 monooxygenase (CYP450) and terpene synthase (TPS) gene families, which might be involved in terpene synthesis alarm pheromone synthesis, were analyzed. Among them, the expression levels of three CYP450s (McraCYP380C, McraCYP4CK1 and McraCYP315A1) in the cornicles were significantly higher than those in the residues. Two isoprenyl diphosphate synthase (IDS) genes, namely farnesyl pyrophosphate synthase (FPPS) and geranyl pyrophosphate synthase (GPPS), were identified. There were no significant differences in the expression levels of FPPS and GPPS between tissues. In addition, potential genes related to alarm pheromone release and transport were analyzed, and two chemosensory protein (CSP) genes were identified as being highly expressed in the cornicle. The expression levels of McraCYP380C, McraCYP4CK1, McraCYP315A1 and McraCSP7 genes in the cornicle were significantly up-regulated. 【Conclusion】 The DEGs in the cornicles and the residue transcriptome of M. crassicauda are successfully identified and analyzed.
