Characterization of the Glutamine Synthetase Gene Family in Wheat (<i>Triticum aestivum</i> L.) and Expression Analysis in Response to Various Abiotic Stresses.

ABSTRACT: Glutamine synthetase plays an essential role in regulating plant growth and development. However, few studies have analyzed the roles of TaGS in wheat under abiotic stress conditions. In this study, we identified and analyzed the members of the TaGS gene family in Triticum aestivum L., focusing on their gene characteristics, phylogenetic evolution, cis-elements, transcriptional and post-translational modifications, and expression profiling in response to abiotic stress. Twelve TaGS genes were divided into four subfamilies. The synteny analysis revealed that wheat and the five other species share GS homologs. Several potential transcription factors were identified as regulators of TaGS genes. TaGS contains 19 microRNA binding sites, phosphorylation sites, and ubiquitination sites. Ta
