Abstract

The relationship of the members of the thaumatin and heat shock protein DnaJ gene families in rice were determined using bioinfomtatic tools. Twenty-nine genes belonging to the thaumatin gene family and sixty-seven genes belonging to the HSP DnaJ gene family were studied. Thaumatin and 1-ISP DnaJ genes were both classified into three groups. This classification was based on the annotation given by the rice annotation project of the Michigan State University. Characterization of these genes showed that those belonging to the same classification share highly similar characteristics including the physico-chemical ones. To further analyze the phylogenomic relationships of these genes to one another. conserved motifs were determined. Fifteen motifs were found in the protein sequences of the thaumatin genes while twenty-five were found in the LISP DnaJ genes. Phylogenetic trees generated for the two family members showed that certain genes clustered together with thaumatin genes having two major clusters and DnaJ genes, twenty-three clusters. Analyses of these genes revealed that clustering was mainly based on the conserved motifs found in their protein sequences.
