Comprehensive analysis of dehydrin genes reveals ZmDHN3 contributes to drought resistance in maize (Zea Mays L.).

ABSTRACT:

Background

Dehydrin (DHN) proteins, belong to subfamily members of late embryogenesis abundant (LEA) proteins, are widely recognized as key determinants in plant abiotic stress tolerance.

Results

In this study, we identified eleven DHN genes in Zea mays and systematically analyzed their evolutionary relationships, structural features, cis-acting elements, expression patterns, protein interaction relation, and function validation in drought resistance. All ZmDHN proteins contained K-segment, and were classified into three subgroups, i.e., KnS-, SKn-, and YnSKn-type. Promoter analysis results showed abundant stress-responsive cis-elements were identified in ZmDHN promoter regions, especially MBS and ABRE elements. Consistently, the most ZmDHNs were induced by cold, heat, salt,
