Thaumatin-like proteins (TLPs) are related to pathogenesis-related-5 (PR-5) family and involved in stress response. Herein, a total of 93 TLP genes were identified the genome Triticum aestivum. Further, we 26, 27, 39, 37 Brachypodium distachyon, Oryza sativa, Sorghum bicolor, Zea mays genomes for comparative characterization, respectively. They could be grouped into small long TLPs with conserved thaumatin signature motif. Tightly clustered exhibited gene protein structure. The physicochemical analyses suggested significant differences between TLPs. Evolutionary role duplication events purifying selection expansion family.
