| description | The transcription factor known as TALE (three-amino acid loop extension) is essential for plant growth, cell differentiation and responses to environmental stresses. Although the <i>TALE</i> gene family has been identified in various plants, there has been a lack of comprehensive whole-genome identification and analysis in Gramineae species. In this study, 123 <i>TALE</i> family genes were identified in five Gramineae species, which can be categorized into two main subgroups: KONX and BELL. Most of the <i>TALE</i> genes in the same subgroup displayed analogous gene structures and conserved motifs. Furthermore, whole genome duplication (WGD) significantly contributes to the expansion of the <i>TALE</i> gene family in Gramineae. The promoter region of <i>TALE</i> genes in Gramineae contains a large number of cis-elements associated with abiotic stress and hormone response. Tissue-specific expression analysis indicated that most <i>OsTALE</i>, <i>ZmTALE</i> and <i>AtTALE</i> genes were highly expressed in stems and leaves. Additionally, RNA-seq data revealed that <i>OsTALE</i>, <i>ZmTALE</i> and <i>AtTALE</i> genes were found to respond to abiotic stress treatments. Furthermore, we found that the expression levels of <i>SbTALE11/19</i> were up-regulated in response to PEG and NaCl treatment, respectively. This study provides a significant reference for further research on the biological function of TALE transcription factors in Gramineae plants. |
