摘要:

为了探究棉花响应苎麻疫霉菌侵染的关键基因并初步解析其参与互作的分子机制,利用Illumina HiseqTM平台对感棉铃疫病棉花种质885系进行了转录组测序和TMT标记定量蛋白组检测,通过差异基因(蛋白)筛选和GO/KEGG富集分析获得响应病原侵染的关键基因,并对关键基因进行生物信息学分析,利用实时荧光定量技术(qPCR)明确关键基因在胁迫环境下的表达模式。结果表明,转录组和蛋白组联合分析共获得50个在基因与蛋白层面均存在显著差异的候选序列;GO和KEGG富集分析显示,差异基因主要富集于植物激素信号转导、植物-病原菌互作、谷胱甘肽代谢以及次级代谢产物生物合成等通路;进一步通过序列比对获得7个候选抗病相关基因,利用qPCR技术对7个候选抗病相关基因检测后发现,Gh_D02G091500Gh_D06G194600Gh_A01G241100Gh_A06G192400Gh_D09G161000的表达受苎麻疫霉菌诱导,其中棉花硝酸还原酶基因的表达差异倍数最高,差异显著性最为明显,并获得了棉花硝酸还原酶基因全长,命名为GhNIA1。综上,GhNIA1可能是参与棉花-苎麻疫霉菌互作的关键基因,并初步明确了GhNIA1的基因特征,为解析GhNIA1参与棉花抗棉铃疫病分子机制及抗病品种选育奠定了基础。

Abstract:

To investigate the key genes in cotton in response to Phytophthora boehmeriae infection and preliminarily elucidate the molecular mechanisms underlying their interaction,it performed transcriptome sequencing and TMT-based quantitative proteomic analysis on the boll rot-susceptible cotton germplasm line 885 using the Illumina HiseqTM platform.By screening for differentially expressed genes(proteins)and conducting GO/KEGG enrichment analyses,key genes involved in the stress response were identified.Bioinformatic analysis was further carried out on these candidate genes,and their expression patterns under pathogen stress were validated via Real-time Quantitative PCR(qPCR).The results showed that combined transcriptomic and proteomic screening identified 50 candidate sequences with significant differential abundance at both the transcriptional and translational levels.GO and KEGG enrichment analyses revealed that the differentially expressed genes were primarily enriched in pathways such as plant hormone signal transduction,plant-pathogen interaction,glutathione metabolism,and the biosynthesis of secondary metabolites.Further sequence alignment screened seven candidate genes related to disease resistance.qPCR verification demonstrated that the expression of Gh_D02G091500,Gh_D06G194600,Gh_A01G241100, Gh_A06G192400,and Gh_D09G161000 was significantly induced by P.boehmeriae.Among these,the cotton nitrate reductase gene exhibited the highest fold change and the most significant differential expression.The full-length sequence of this nitrate reductase gene was cloned and designated GhNIA1.In conclusion,it identified GhNIA1 as a key gene involved in the cotton-P.boehmeriae interaction and provided preliminary characterization of GhNIA1.These findings lay a theoretical foundation for further analysis of the molecular mechanism by which GhNIA1 participates in cotton resistance to boll rot and for breeding resistant varieties.
