Genome-Wide Exploration and Characterization of the Gene Family's Expression Patterns in Response to Abiotic Stresses in Siberian Wildrye ( L.).

Siberian wildrye ( L.), a model Gramineae plant, has high eco-economic value but limited seed and forage yield. transcription factors are widely regarded as influencing yield and quality and being crucial for growth and development; still, this gene family in Siberian wildrye remains unexplored. Therefore, this study looked at the Siberian wildrye gene family's reaction to several abiotic stresses, its expression pattern, and its potential evolutionary path. Fifty-four members of the gene family were discovered. There are two major subfamilies based on the phylogenetic tree: 27 of Class I () and 27 of Class II (12 -type and 15 -type). Gene structure, conserved motif, and sequence alignment analyses further validated this classification. -elements found in the promoter region of are associated with lots of plant hormones and stress-related reactions, covering drought induction and cold tolerance. , , and may regulate tillering and lateral branch development. 's relative expression was significant under five stresses. Additionally, eight genes are potential miR319 targets. These findings highlight the critical significance of the gene family in Siberian wildrye, laying the groundwork for understanding the function of the EsTCP protein in abiotic stress studies and high-yield breeding.
