| description | GOLDEN2-LIKE (GLK) transcription factors are a subfamily of GARP family transcription factors, which play an essential function in plant growth and development as well as stress response during abiotic and biotic stress conditions. This study reports <i>GLK</i> genes in the <i>Arabidopsis thaliana</i> genome in-depth and identified 55 <i>AtGLK</i> genes in the Arabidopsis genome. Phylogenetic analyses resolved these <i>GLK</i> gene clusters into seven groups. A Ka/Ks ratios analysis indicated that they had experienced purifying selection. Many essential cis elements are present in the promoter regions of <i>AtGLK</i> genes associated with plant hormones, light, and stress. The expression profile from RNA-Seq data revealed that 29.1% of them had relatively high expression in all tested tissues or organs, indicating their crucial housekeeping function in plant growth and development. However, many other <i>GLK</i> members were selectively expressed in particular tissues or organs. In silico study of the transcriptional regulation of <i>AtGLKs</i> indicated that it is strongly regulated by cold, drought, osmotic, salt, and metal ion stressors. Our research provides essential information for the functional studies of each <i>GLK</i> gene in different species in the future. |
