Identification and Characterization of a Mutant PV-PUR Gene Responsible for the Purple Phenotype of Snap Bean (Phaseolus vulgaris L.).

ABSTRACT: Pod color is a major economic trait of snap beans (Phaseolus vulgaris L.), among which the pod with a purple stripe is more attractive to people. A stable purple mutant with purple stripes on the pods was obtained by artificial mutagenesis with the high generation snap bean inbred line 'A18-1'. In order to reveal the genetic factors and pathways responsible for the purple appearance in snap bean, we performed transcriptome and metabolome analyses using the green stem and yellow pod cultivar 'A18-1' and its purple mutant 'pv-pur' via 60Co-γ radiation. Transcriptome analysis showed that three genes in the anthocyanin biosynthetic pathway were differentially expressed, among which the expression level of F3'5'H (Phvul.006G018800) was increased in the mutant 'pv-pur', while expression of F3'H
