Maize is a significant food and feed product, and abiotic stress significantly impacts its growth and development.
Arabidopsis Toxicosa en Levadura (
ATL), a member of the RING-H2 E3 subfamily, modulates various physiological processes and stress responses in
Arabidopsis. However, the role of
ATL in maize remains unexplored. In this study, we systematically identified the genes encoding
ATL in the maize genome. The results showed that the maize
ATL 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
ATL family genes were significantly different in different tissues. Examination of the abiotic stress data revealed that the expression levels of
ATL 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
ZmATL10 and its homologous gene
AtATL27 in
Arabidopsis. The results showed that overexpression of the
ZmATL10 and
AtATL27 genes enhanced resistance to high-temperature stress.
