Genome-wide characterization and expression profiling of the <i>TGA</i> gene family in sweet orange (<i>Citrus sinensis</i>) reveal <i>CsTGA7</i> responses to multiple phytohormones and abiotic stresses.

ABSTRACT: Citrus is widely recognized as one of the most economically important fruit crops worldwide. However, citrus growth is frequently hindered by external environmental stresses, which severely limit its development and yield. The TGA (TGACG motif-binding factor) transcription factors (TFs) are members of the bZIP family and play essential roles in plant defense responses and organ development. Nevertheless, the systematic identification and functional analysis of the TGA family in citrus remains unreported. In this study, genome-wide analysis identified a total of seven CsTGA TFs in Citrus sinensis, which were classified into five subgroups. Phylogenetic and syntenic analysis revealed that the CsTGA genes are highly conserved, with no tandem or segmental duplication events among
