摘要:

目的 鉴定大豆锌铁转运蛋白(zinc-regulated transporter/iron-regulated transporter, ZIP)基因家族成员,分析GmZIP基因家族成员在铝胁迫下的表达模式,为阐明GmZIP家族的生物学功能奠定基础。 方法 通过生物信息学鉴定大豆基因组中GmZIP基因家族成员,根据鉴定结果构建其系统发育树,预测蛋白网络图,分析基因家族成员的共线性关系、基因结构及启动子顺式作用元件。经转录组分析GmZIP基因家族成员在大豆不同组织中及在铝胁迫下的表达模式。 结果 在大豆基因组中鉴定到26个GmZIP基因家族成员,分布在14条染色体上,分为Ⅰ-Ⅴ亚家族。GmZIP基因家族成员基因结构较为保守,均含有ZIP保守结构域,含有多个外显子,且不同成员之间外显子数量差异明显。转录组结果显示,大部分GmZIP成员在大豆根和根瘤组织均有较高表达水平;在铝胁迫下,有3个成员(GmZIP6GmZIP12GmZIP25)在耐铝大豆种质南农99-6中上调表达,在铝敏感大豆种质中豆32中2个上调表达(GmZIP20GmZIP25)、1个下调表达(GmZIP23)。蛋白预测结果显示,26个GmZIP蛋白中有16个存在互作关系,其中铝胁迫下差异表达基因有GmZIP23GmZIP25。荧光定量PCR检测发现,耐铝种质中GmZIP25在铝处理72 h后表达量最高,而铝敏感种质中GmZIP25在处理12 h时表达量达到最大值。 结论 推测GmZIP25在大豆响应铝胁迫中具有重要作用。

Abstract:

Objective Identifying and analyzing the expressions of GmZIP family members under aluminum stress in soybean lays the foundation for elucidating the biological function of GmZIP family. Method The members of GmZIP gene family were identified by bioinformatics method, which was used to establish the phylogenetic tree, predict protein network map and analyze the collinearity relationships, gene structure, and promoter cis-acting elements. Based on transcriptome sequencing, the expression patterns of GmZIP gene family in different tissues and under aluminum (Al) stress were analyzed. Result A total of 26 GmZIP were identified in the whole soybean genome, which were unevenly distributed on 14 chromosomes and divided into Ⅰ-Ⅴ subfamilies by phylogenetic analysis. The gene structure of GmZIP members were relatively conservative. All of GmZIP members contained ZIP conserved domain, multiple exons, and significantly different introns. Transcriptome analysis of different soybean tissues showed that most of GmZIP members had high expressions in the soybean root and nodule tissues. Three members of GmZIP (GmZIP6, GmZIP12, and GmZIP25) were up-regulated in Al-tolerant soybean germplasm Nannong 99-6, two members (GmZIP20 and GmZIP25) were up-regulated while one was down-regulated (GmZIP23) in Al-sensitive soybean germplasm soybean Zhongdou 32. The protein prediction results show that 16 of 26 GmZIP have interaction relationships, among which GmZIP23 and GmZIP25 were differentially expressed under Al toxicity stress. Based on fluorescence quantitative PCR detection, the expression of GmZIP25 in Al-resistant germplasm reached the highest at 72 h under aluminum stress treatment, while that in Al-sensitive germplasm reached the highest at 12 h. Conclusion These results suggest that GmZIP25 may play an important role in response to aluminum stress of soybean.
