AB - Plant metallothioneins (MTs) are small proteins, having rich cysteine residues andappear to play key roles in metal homeostasis. In current study, MTs of 9 grass species (<em>Brachypodium distachyon</em>, <em>Festuca rubra</em>, <em>Hordeum vulgare</em>, <em>Oryza sativa japonica</em>, <em>Oryza sativa indica</em>, <em>Saccharum officinarum</em>, <em>Sorghum bicolor</em>, <em>Triticum aestivum</em>, and <em>Zea mays</em>) were used for in silico comparative analysis. Physicochemical analyses showed that pIvalues and GRAVY index were found to be in the range of (4.44) - (7.36) and (-0.037) - (-0.376), respectively. All MTs investigated in this study exhibited hydrophilic characterand 8 of 9 MTs had acidic nature. Also, there were no sequences containing tryptophan(Trp) residues. While the highest and lowest similar sequence identities were foundbetween <em>S. bicolor</em> & <em>S. officinarum</em> (0.928), and <em>Z. mays</em> & <em>H. vulgare</em> (0.183), respectively. Phylogenetic analysis revealed that one main group observed including two subgroups.The highest bootstrap value was observed between <em>S. bicolor </em>and <em>S. officinarum</em> (92%). Interestingly,<em> H. vulgare</em> appears not to be within any grass species group.
