摘要:
利用隐马可链夫模型（HMM）对芝麻全基因组Hsp70基因进行了系统分析，共鉴定出21个Hsp70基因，其中17个属于Dnak基因亚家族，4个属于Hsp110/SSE基因亚家族。根据系统进化树分析和亚细胞定位结果，将芝麻21个Hsp70基因分为6个亚组，其中I亚组3个，定位于叶绿体；II亚组2个，定位于线粒体；III亚组5个，定位于内质网；IV亚组6个，定位于细胞质基质；V亚组4个，属于Hsp110/SSE基因家族；VI亚组1个。芝麻Hsp70基因启动子区域顺式作用元件功能预测结果显示，Hsp70基因参与芝麻的生长发育和逆境胁迫响应等生理过程。
Abstract:
In this study, Hsp70 genes in the sesame genome were systematically analyzed with Hidden Markov Model (HMM). A total of 21 SiHsp70 genes were identified, among which, seventeen belong to DnaK subfamily and four of them belong to Hsp110/SSE subfamily. Based on the phylogenetic and subcellular localization analysis, the 21 SiHsp70 genes were classified into 6 subgroups. Three chloroplast-localized genes belong to subgroup I, two mitochondrial-localized genes belong to subgroup II, five ER-localized genes belong to subgroup III, six cytoplasmic-localized genes belong to subgroup IV, four Hsp110/SSE-type genes belong to subgroup V, and one gene belongs to subgroup VI. The cis-acting elements in the promoters of SiHsp70 genes were further analyzed, and the results demonstrated that they were involved in growth, development and stress response.
