Additional file 1: Supplementary Table S1. List of retrieved MYB59 protein sequences from 56 plants species using NCBI and EnsemblPlants. Supplementary Table S2. List of primers with Tm and product size used in this study. Supplementary Table S3. Most conserved three motifs of MYB59 proteins in 56 plant species detected by using MEME tool. Supplementary Fig. S1. Multiple sequence alignments of the MYB59 proteinsobtained with Clustal Omega. Identical and similar residues were shaded as black and grey, respectively. Shading of the multiple-alignment file was done using BoxShade by ExPASy. Supplementary Fig. S2. Location of rice MYB59 gene on rice chromosome 1. Supplementary Fig. S3. Gene structure of rice MYB59 indica. Exons, introns, and untranslated regions are marked by round red rectangles, black lines, and blue rectangles, respectively. The scale bar at the bottom estimates the lengths of the exons, introns, and untranslated regions.
