BACKGROUND
BES/BZR family genes have vital roles in plant growth, development, and adaptation to environmental stimuli. However, they have not yet been characterized and systematically analyzed in wheat and foxtail millet.
RESULTS
In the current study, five common and two unique BES/BZR genes were identified by genome-wide analysis in wheat and foxtail millet, respectively. These genes were unevenly distributed on 14 and five chromosomes of wheat and foxtail millet, respectively, and clustered in two subgroups in a phylogenetic analysis. The BES/BZR gene family members in each subgroup contained similar conserved motifs. Investigation of cis-acting elements and expression profile analysis revealed that the BES/BZR genes were predominantly expressed in leaf tissues of wheat and foxtail millet seedlings and responded to brassinosteroid, abscisic acid, and NaCl treatments.
CONCLUSIONS
Our results provide a basis for future studies on the function and molecular mechanisms of the BES/BZR gene family in wheat, foxtail millet, and other plants.
背景
BES/BZR家族基因在植物生长、发育以及对环境刺激的适应过程中发挥着至关重要的作用。然而，它们在小麦和谷子中尚未得到鉴定和系统分析。
结果
在本研究中，分别通过全基因组分析在小麦和谷子中鉴定出了5个常见的和2个独特的BES/BZR基因。这些基因分别不均匀地分布在小麦的14条染色体和谷子的5条染色体上，并且在系统发育分析中聚为两个亚组。每个亚组中的BES/BZR基因家族成员包含相似的保守基序。对顺式作用元件的研究和表达谱分析表明，BES/BZR基因主要在小麦和谷子幼苗的叶片组织中表达，并对油菜素内酯、脱落酸和NaCl处理有响应。
结论
我们的结果为未来研究BES/BZR基因家族在小麦、谷子及其他植物中的功能和分子机制提供了基础。
