MAPK-dependent copper tolerance mechanisms revealed by integrated physiology and transcriptomics in peanut

This study provides insights into the regulatory mechanisms that peanut plants employ to cope with copper stress. The findings highlight the roles of <i>MPK4</i>, NAC, and LBD in the plant's response to copper stress and suggest that these genes could be targeted in breeding programs to develop copper-tolerant peanut cultivars. The results may provide theoretical support for the development of such cultivars.
