Genome-Wide Identification, Exogenous Hormone Response, Gene Structure, and Conserved Motif Analysis of the Gene Family in .

The , a perennial shrub belonging to the Cerasus genus, is native to China and holds significant ecological and economic importance. Growth regulation factors () are a family of transcription factors (TF) that play a key role in plant growth and development. This research entailed an in-depth examination of the family in , exploring its significance in the evolution of . Twelve genes were identified in the genome. Named separately as , , , , , , , , , , , and Phylogenetic analysis divided twelve genes into five subfamilies. The gene structure, pattern, and cis-regulatory components of the gene family were analyzed. In addition, according to collinearity analysis, there are six collinearity with , twelve collinearity with , eight collinearity with , and three collinearity with . Intraspecific collinearity analysis revealed the presence of three pairs of tandem repeat genes in the dwarf cherry genome. Identifying cis-acting elements revealed the prominent presence of gibberellin reaction elements, which are widely distributed in the promoter region. Cluster heatmap analysis showed that had the highest expression levels in fruits and stems. is highly expressed in red fruits of different colors, while and are highly expressed in yellow fruits. This study mainly focused on dwarf cherries treated with gibberellin. As the treatment time increased, the gene showed different expression levels. , , , and were up-regulated under gibberellin treatment. These genes all contain hormone-responsive cis-acting elements, indicating tht the gene family plays a vital role under gibberellin treatment in . The results laid the foundation for further research on the biological functions of the genes in .
