| 摘 要： | 本研究利用生物信息学方法对玉米BTB家族基因进行系统发育、保守结构域、组织特异性以及在玉米抵抗生物和非生物胁迫过程中的表达规律进行分析。发现玉米70个BTB家族蛋白除AC206223.3外均含有保守的BTB结构域,可分为11个亚家族。玉米BTB家族基因具有明显的组织表达特性,在高温、低温、紫外、高盐和干旱胁迫下以及拟轮枝镰孢(Fusarium verticillioide)侵染过程中的表达水平呈现出明显的差异。BTB-TAZ亚家族基因在水杨酸、茉莉酸、乙烯处理后表达水平发生明显的变化。结果表明BTB家族基因在玉米抵抗生物和非生物胁迫中发挥重要的作用,为阐明玉米BTB家族基因的功能及其机制奠定了基础。

| Abstract: | In this study, bioinformatics methods were used to conduct phylogenetic, conservative domain, tissue-specific, and expression regularity analysis of BTB family genes during resistance to biological and abiotic stresses in Zea mays. It was found that all 70 BTB family proteins in Z. mays contain a conserved BTB domain except AC206223.3, which can be divided into 11 subfamilies. The BTB family genes of maize had obvious tissue expression characteristics, and the expression levels show obvious differences under high temperature, low temperature, ultraviolet, high salt, drought stress, and in the process of Fusarium verticillioide infection. The expression levels of BTB-TAZ subfamily genes were significantly changed after SA, JA and ET treatment. These results showed that BTB family genes play an important role in resisting biological and abiotic stresses. It would lay the foundation for elucidating the function and mechanism of BTB family genes in Z. mays. |
