The molecular mechanism of the underlying genes involved in the process of fruit ripening in Capsicum (family Solanaceae) is not clearly known. In the present study, we identified orthologs of 32 fruit development/ripening genes of tomato in Capsicum, and validated their expression in fruit development stages in C. annuum, C. frutescens, and C. chinense. In silico expression analysis using transcriptome data identified a total of 12 out of 32 genes showing differential expression during different stages of fruit development in Capsicum. Real time expression identified gene LOC107847473 (ortholog of MADS-RIN) had substantially higher expression ( > 500 folds) in breaker and mature fruits, which suggested the non-climacteric ripening behaviour of Capsicum. However, differential expression of Ehtylene receptor 2-like (LOC107873245) gene during fruit maturity supported the climacteric behaviour of only C. frutescens (hot pepper). Furthermore, development of 49 gene based simple sequence repeat (SSR) markers would help in selection of identified genes in Capsicum breeding.
