Maize is a significant food and feed product, and abiotic stress significantly impacts its growth and development. (), a member of the RING-H2 E3 subfamily, modulates various physiological processes and stress responses in . However, the role of in maize remains unexplored. In this study, we systematically identified the genes encoding in the maize genome. The results showed that the maize family consists of 77 members, all predicted to be located in the cell membrane and cytoplasm, with a highly conserved RING domain. Tissue-specific expression analysis revealed that the expression levels of family genes were significantly different in different tissues. Examination of the abiotic stress data revealed that the expression levels of genes fluctuated significantly under different stress conditions. To further understand the biological functions of maize ATL family genes under high-temperature stress, we studied the high-temperature phenotypes of the maize ZmATL family gene and its homologous gene in . The results showed that overexpression of the and genes enhanced resistance to high-temperature stress.
玉米是一种重要的粮食和饲料产品，非生物胁迫显著影响其生长和发育。（）作为 RING-H2 E3 亚家族的成员，调节在中的各种生理过程和应激反应。然而，在玉米中，的作用尚不清楚。在本研究中，我们系统地鉴定了玉米基因组中编码的基因。结果表明，玉米家族由 77 个成员组成，所有成员都预测位于细胞膜和细胞质中，具有高度保守的 RING 结构域。组织特异性表达分析显示，家族基因的表达水平在不同组织中存在显著差异。对非生物胁迫数据的分析表明，在不同胁迫条件下，基因的表达水平波动显著。为了进一步了解玉米 ATL 家族基因在高温胁迫下的生物学功能，我们研究了玉米 ZmATL 家族基因及其同源基因在高温下的表型。结果表明，过表达和基因增强了对高温胁迫的抗性。
