Abstract:

BGLU genes play crucial role in the defense of biotic and abiotic stresses, this study identified the members of the BGLU family in cotton via bioinformatics methods. The sequence features, conserved domain structure, chromosome location, promoter elements and other family features were analyzed, and the transcriptome data and qRT-PCR were used to analyze the pathogenic stress response pattern of BGLU family genes. The results showed a total of 53 BGLU genes were identified and divided into 6 sub-families according to the phylogenetic relationship in upland cotton, and some genes were specifically expressed under pathogen stress. qPCR analysis and RNAseq data showed that GhBGLU5GhBGLU14GhBGLU18GhBGLU26 and GhBGLU34 maintained higher expression level in resistant and susceptible cottons, implying that these genes positively regulated cotton Verticillium wilt resistance. This study provided theoretical basis for further analyzing the functions and molecular mechanisms of the BGLU genes in cotton.

Key words: Gossypium hirsutum, BGLU gene family, phylogenetic analysis, expression profiling

摘要:

植物BGLU基因在生物和非生物胁迫防御中起着重要作用,利用生物信息学手段对陆地棉(Gossypium hirsutumBGLU家族成员进行全基因组鉴定,对序列特征、保守域结构、染色体定位、启动子元件等家族特征进行了分析,并进一步结合转录组数据和qRT-PCR分析了BGLU基因家族的病菌胁迫响应模式。结果表明,共鉴定出53个陆地棉BGLU基因,根据系统发育进化关系分为6个亚族,部分基因在病菌胁迫下特异性表达。荧光定量和转录组测序结果表明,GhBGLU5GhBGLU14GhBGLU18GhBGLU26GhBGLU34在抗病棉花中的表达水平显著高于感病品种,推测这些基因正向调控棉花黄萎病抗性。上述结果为进一步分析棉花BGLU家族基因的功能以及分子机制提供一定的理论基础。
