    摘要:

    WUSCHEL-related homeobox (WOX)转录因子是植物特有的转录因子,具有调控植物生长发育和非生物胁迫响应的作用。该研究通过生物信息学的方法对GuWOX基因家族进行分析,并利用qRT-PCR方法检测该基因家族在不同组织和非生物胁迫下的表达情况,利用RT-PCR方法克隆得到4个GuWOX基因。结果显示,(1)GuWOX基因家族共有16个成员,均含有保守的HD,为亲水性不稳定蛋白质;系统进化分析表明,GuWOX基因家族分为3个进化支(远古支、中间支和现代支);启动子序列中包括响应多种逆境和激素的顺式作用元件。(2)qRT-PCR结果显示,在侧根中GuWOX1的表达量最高,在茎中GuWOX15的表达量最高;GuWOX在盐、无磷和GA3处理后不同时间段都有表达;干旱和ABA处理GuWOX15的表达模式相近,且在处理12 h时均上调表达。(3)成功克隆得到GuWOX1、GuWOX5、GuWOX6、GuWOX12基因,其长度分别为557 bp、707 bp、716 bp和578 bp,分别编码184、237、237和191个氨基酸。该研究结果表明,GuWOX基因参与甘草发育、对逆境胁迫的响应以及植物激素调节,为进一步分析GuWOX基因功能奠定了基础。

    Abstract:

    WUSCHEL-related homeobox (WOX) transcription factors are plant-specific transcription factors that can regulate plant growth and development and the response to abiotic stress. In this study, the GuWOX gene family was analyzed by bioinformatics methods, the qRT-PCR method was used to detect the expression of this gene family in different tissues and abiotic stress, and four GuWOX genes were cloned by RT-PCR method. The results showed that: (1) there were a total of 16 GuWOX genes, all of which contained a conserved HD domain and were hydrophilic and unstable proteins. Phylogenetic tree analysis showed that the GuWOX family was divided into 3 major clades (e.g., the Ancient clade, the Intermediate clade and the Modern/WUS clade). Numerous stress and hormone-responsive cis-elements were observed in the GuWOX promoter regions. (2) qRT-PCR showed that the expression of GuWOX1 was the highest in lateral roots and GuWOX15 was the highest in stems. At different time intervals, GuWOX was expressed under salt, phosphorus free and GA3 treatments. The expression pattern of GuWOX15 was similar under drought stress and ABA treatment, and the expression was up-regulated at 12 h. (3) GuWOX1, GuWOX5, GuWOX6, GuWOX12 genes were cloned and their lengths were 557 bp, 707 bp, 716 bp, 578 bp, encoding 184, 237, 237, 191 amino acids, respectively. The results of this study indicate that GuWOX genes were involved in the development of G. uralensis, the response to adversity stresses, and the regulation of plant hormones. This result laid the foundation for further analysis of GuWOX gene function.
