Genome-wide characterization and expression analysis of the GATA transcription factor family in response to salt and drought stress in barley (<i>Hordeum vulgare</i> L.).

ABSTRACT: GATA transcription factors play a crucial role in regulating plant growth and development as well as stress responses. However, systematic analysis of GATA genes in barley remains uncharacterized, and their functional roles in salt and drought stress responses are poorly understood. This study conducted genome-wide identification and gene expression analysis of the GATA transcription factor family in barley through bioinformatics approaches. A total of 27 HvGATA genes were identified and divided into 4 subfamilies (I-IV), which were unevenly distributed on 7 chromosomes. Overall tertiary structural similarity of GATA proteins existed with differences, but similarity within the same subfamily was higher. Fragment repetition has been identified as the main driving factor for th
