A WRKY Transcription Factor, <i>ZmWRKY82</i>, Conferred Enhanced Drought Stress Tolerance in Maize.

ABSTRACT: Members of the WRKY transcription factors (TFs) family play crucial roles in biotic and abiotic stress responses in plants, but their roles in response to drought stress in maize (Zea mays L.) have not been fully elucidated. Maize ZmWRKY82, a group IIc WRKY gene, was isolated from maize using reverse transcription polymerase chain reaction (RT-PCR). Using the UniProt online database, we found that ZmWRKY82 encodes a 222-amino protein with conserved WRKYGKK and C-X₄-C-X₂₃-H-X₁-H motifs. ZmWRKY82 is strongly induced by polyethylene glycol (PEG), abscisic acid (ABA), methyl jasmonate (MeJA), salicylic acid (SA), and ethephon (ETH) treatments. The ZmWRKY82 protein was located in the cell nucleus. ZmWRKY82 had transcriptional activati
