Transcriptional factors are the major regulators of plant signaling pathways in response to environmental stresses i.e., drought, salinity and cold. Hereby, the GhMYB108-like was characterized to determine whether it regulate these stresses. The GhMYB108-like cDNA consisted of 1107 base pairs (bp) with 807 open reading frame encoded a protein of 268 amino acids. Its isoelectric point and molecular weight are 5.51 and 30.3 kDa respectively. Phylogenetic analysis and online databases revealed that GhMYB108-like proteins are closely related with the Arabidopsis thaliana MYB2. Important cis-elements were detected in the promotor region of GhMYB108-like responding to stresses and phytohormones. The 3D structure of GhMYB108-like protein has been predicted. In addition, various physico-chemical properties of GhMYB108-like have been determined. Subcellular localization confirmed that GhMYB108-like are nuclear localized protein. Quantitative expression analysis showed that polyethylene glycol and salt treatments significantly induced the expression of GhMYB108-like. Overall, our findings suggest that GhMYB108-like is an important gene that would plays important regulatory role in response to drought and salt stresses.
