Fine mapping of the Chilli veinal mottle virus resistance 4 (cvr4) gene in pepper (Capsicum annuum L.).

ABSTRACT:

Key message

The single recessive Chilli veinal mottle virus resistance locus, cvr4, was fine-mapped in pepper through bulked segregant RNA sequencing combined with gene silencing analysis. Chilli veinal mottle virus (ChiVMV) is a widespread pathogen affecting the production of peppers (Capsicum annuum L.) in Asia and Africa. Few loci conferring resistance to ChiVMV have been identified, severely limiting the development of resistant cultivars. To identify ChiVMV resistance genes, we constructed an F_2:3 segregating population derived from a cross between the ChiVMV-resistant cultivar 'CV9' and the susceptible cultivar 'Jeju'. The inheritance study of F_2:3 populations showed a 1:3 ratio of resistant to susceptible individuals, demonstrating the existence of a si
