Abstract: In this study, we carried out genome-wide analyses to explore expansin gene family in the genome of indica rice. Reference nucleotides were chosen as query sequences for searches in the indica rice genome database. Clones having genomic sequences similar to expansin were taken and converted to amino acid sequences. Putative sequences were subjected to PROSITE and Pfam databases, and 21 signature-sequences-related expansin gene family was obtained. The presence of transmembrane domains was also predicted for all 21 expansin proteins. A phylogenetic tree was generated from the alignments of the proteins sequences to examine the phylogenetic relationship of indica rice expansin proteins.

Keywords: Oryza sativa; genome analysis; expansin gene family; indica rice; phylogenetic tree; protein sequences; bioinformatics.
