摘要:

研究旨在对赤松梢斑螟(Dioryctria sylvestrella)气味降解酶(odorant-degrading enzyme, ODE)相关基因进行鉴定、分类及组织表达模式分析,以期为该害虫的绿色高效防治技术提供理论依据。在赤松梢斑螟雌、雄触角转录组数据中筛选出4种ODEs基因:羧酸酯酶(carboxylesterases, CXEs)、醛氧化酶(aldehyde oxidases, AOXs)、谷胱甘肽转移酶(glutathione S-transferases, GSTs)和细胞色素P450氧化酶(cytochrome P450s, CYPs),对这些基因进行生物信息学分析和同源建树、命名;选取触角中FPKM值较高的候选基因进行后续验证,并采用RT-qPCR技术分析所选基因在成虫不同组织中的特异表达情况。研究共鉴定出137个候选ODEs相关基因,包括39个DsylCXEs、6个DsylAOXs、32个DsylGSTs和60个DsylCYPs。RT-qPCR结果表明,18个DsylODEs在触角中的表达量显著高于其他组织。在赤松梢斑螟的触角中显著表达的ODEs基因类型主要为谷胱甘肽转移酶与细胞色素P450。研究首次筛选出了潜在的具有较强气味降解能力的赤松梢斑螟ODEs基因,为进一步探究赤松梢斑螟在嗅觉识别过程中的气味降解机制奠定了基础。

Abstract:

This study aimed to identify, classify, and analyze the tissue expression patterns of odorant-degrading enzyme (ODE)-related genes in Dioryctria sylvestrella (Lepidoptera: Pyralidae), thereby providing a theoretical basis for developing green and efficient control technologies against this pest. Four families of ODE-related genes were screened from the transcriptome data of female and male antennae of D. sylvestrella, including carboxylesterases (CXEs), aldehyde oxidases (AOXs), glutathione S-transferases (GSTs), and cytochrome P450 monooxygenases (CYPs). These genes were subjected to bioinformatics analysis, homologous sequence alignment, phylogenetic tree construction, and standardized naming. Candidate genes with relatively high FPKM values in antennae were selected for subsequent validation, and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was employed to analyze the tissue-specific expression profiles of the selected genes in different adult tissues. A total of 137 candidate ODE-related genes were identified, including 39 DsylCXEs, 6 DsylAOXs, 32 DsylGSTs, and 60 DsylCYPs. RT-qPCR results showed that 18 DsylODEs exhibited significantly higher expression levels in antennae than in other tissues. Among these antennae-enriched ODE genes, glutathione S-transferases (GSTs) and cytochrome P450 monooxygenases (CYPs) were the dominant families. This study is the first to screen and identify potential D. sylvestrella ODE genes with strong odor-degrading capabilities, which established a foundational framework for further investigating the odor degradation mechanisms involved in the olfactory recognition process of D. sylvestrella through sequence characterization and gene expression profiling.
