摘要: bZIP蛋白是植物转录因子中最大和最保守的一类转录因子, 参与调控植物生长发育等多种生命活动。谷子(Setaria italica)是一种重要的C4杂粮作物, 其bZIP基因家族与功能报道较少。利用生物信息学工具, 从谷子全基因组中鉴定出73个SibZIP转录因子, 划分为A、B、C、D、E、G、H、I和X等亚家族。与已测序的禾谷类作物相比, 谷子SibZIP基因家族在进化中发生缩减。在谷子SibZIP蛋白中检测到25种不同的保守氨基酸基序。RNA-seq和定量PCR检测结果表明, 在干旱和盐胁迫条件下, 多数SibZIPs基因不同程度地被诱导表达, 预示着部分SibZIP成员在谷子干旱和盐胁迫响应中起重要作用。共表达关联性分析进一步揭示19个谷子SibZIP转录因子可通过与蛋白激酶或NPR1相关调节蛋白等互作介导谷子胁迫响应。研究结果为全面解析谷子SibZIPs基因结构与生物学功能、抗旱分子机制以及分子育种提供了新信息。

Figure 4 Correlation analysis of co-expression of Setaria italica SibZIP genes under stressed conditions The expression data of the protein coding genes in foxtail millet under stressed conditions were derived from Setaria italica v2.1 database. Bioinformatics tools in String Functional Protein Interaction website (http://string-db.org/) were employed for correlation analysis of co-expression of SibZIP genes. Red circle represents SibZIP genes and the related genes involved in regulation network responsible for stress responses. The size of circle indicates the significance of the protein with bigger size having more importance in the related pathway. Blue solid line shows correlation between the related proteins with thinker line meaning stronger correlation. Blue dotted line shows possible interraction between the related proteins. The corresponding SibZIP protein name for each foxtail millet protein (red color circle representive) are list in Table 2.
