摘要: Pigeonpea is the main protein source for more than one billion people, and it shows a strong adaptation to biotic stress and abiotic stress. Gene duplication is a fundamental process in genome evolution. Although the draft sequence of the pigeonpea genome has been available since 2011, further analysis of tandem duplicated genes (TDGs) and their contribution to the evolution of pigeonpea has not been reported. In this study, we identify 3211 TDGs in the pigeonpea genome and KEGG enrichment analysis of these genes shows that the TDGs are significantly enriched in resistance-related pathways. In addition, we find that TDGs are more abundant in retrotransposon-related genes in pigeonpea than in the other species included in our study. These results indicate that stress resistance in pigeonpea may be ascribed to resistance-related pathways and retrotransposons originating from tandem duplications. Our study will provide an important basis for further research in pigeonpea breeding.
