SRO(Similar to radical-induced cell death 1)蛋白是植物特有的一类小蛋白家族转录因子,在植物抵御生物/非生物胁迫(盐害,干旱,高温,低温,水涝等)和生长发育中发挥着重要的作用.尽管SROs已在许多物种中进行了研究,但在马铃薯中仍缺乏系统鉴定.基于马铃薯已公布的基因组数据对马铃薯SRO蛋白家族进行全基因组鉴定和生物信息学分析,共鉴定到9个StSROs家族成员,不均匀分布在5条染色体上,亚细胞定位预测该基因全部成员定位在细胞核上.启动子上游鉴定到了大量与生长发育、植物激素响应和生物/非生物胁迫有关的顺式作用元件,同时预测了调控该基因的miRNAs.该基因各成员对不同激素处理响应程度存在明显差异.上述结果为马铃薯StSROs潜在的分子功能提供了理论依据,表明该基因在马铃薯非生物胁迫方面可能具有重要意义.
Genome-wide Identification and Bioinformatics Analysis of SRO Family in Solanum tuberosum L.
SRO(Similar to radical induced cell death 1)proteins are a plant-specific small protein family of transcription factors that play an important role in plant responses biotic,abiotic stresses such as salinity,drought,high temperature,low temperature,waterlogging,as well as growth and development.Although SROs have been studied in many species,SROs were still not systematically identified in potatoes.Genome identification and bioinformatics analysis of potato SRO protein family based on the published genome data of Solanum tuberosum L.,nine members of StSROs family were isolated and identified,which were unequally distributed on five chromosomes,subcellular localization predicted that all members of the gene were located in the nucleus.Upstream promoter region analysis found a large number of cis-acting elements related to growth,development,plant hormone response and biotic/abiotic stress,and the miRNA regulating the gene was predicted.There were significant differences in the degree of response to different hormone treatments among members of this gene.These results provided a theoretical basis for the potential molecular function of potato StSROs,indicating that the gene may be of great significance in potato abiotic stress.
