摘要:

为探索甜瓜肌醇半乳糖苷合成酶(GolS)基因的特性及其响应低温胁迫的表达模式,利用生物信息手段对其家族成员进行全基因组鉴定及染色体位置、进化关系、基因结构、启动子顺式作用元件、组织特异性表达和在低温胁迫下的表达模式等进行分析。结果鉴定出12个CmGolS不均匀地分布在9条染色体上,并且在系统发育树中被分为5族。理化性质分析表明甜瓜CmGolS蛋白均为亲水性蛋白。基因结构分析表明CmGolS基因保守性较高,多有2 ~ 5个内含子且含有与胁迫和赤霉素、生长素、脱落酸等激素响应相关的顺式作用元件以及保守基序“DxD”和“HxxGxxKPW”。CmGolS具有组织表达特异性,大多在雄花中表达,并且在低温胁迫处理下相对表达量大多呈显著上调趋势,表明CmGolS参与响应低温胁迫。

Abstract:

In order to study the characteristics of melon(Cucumis melo L.)GolS family genes and their responses to low temperature stress,members of the melon GolS family of genes were identified using bioinformatics. The chromosomal locations,evolutionary relationships,genetic structure,promoters,cis-acting elements,tissue-specific expressions and expression patterns under low temperature stress were predicted using bioinformatics. After exhaustive analysis,12 CmGolS genes were successfully identified and found to be unevenly distributed across nine chromosomes. The analyses of phylogenetic showed that these genes were divided into 5 groups. Physicochemical analysis showed that all CmGolS proteins were hydrophilic proteins. The CmGolS genes were highly conserved and they have 2-5 introns. These genes contain conserved motifs“DxD”“HxxGxxKPW”and many cis-acting elements,which related to stress and hormones such as gibberellin,auxin and abscisic acid. In addition CmGolS genes have tissue specific expressions,most of them are expressed in male flowers. And the relative expression of most of them show a significant up-regulation trend under low temperature stress that indicated CmGolS genes can actively participate in the processes of responding to low temperature stress.
