| Abstrakt: | Petal color is an important trait for both ornamental purposes and also for attracting pollinators. Here, we report a mutation of Brassica rapa R-o-18 with pale yellow petals that we retrieved from an EMS population and named whiter shade of pale ( wsp ). Phenotypic segregation ratio of an F2 mapping population indicates the phenotype is controlled by a single recessive gene. Mapping data from the whole genome sequencing coupled with allele frequency analysis suggests the mutation is located in a ~2 Mbp interval on chromosome 2. The interval contains a putative esterase/lipase/thioesterase protein previously demonstrated to account for floral color in B. rapa . We demonstrate that wsp carries a G to A missense mutation causing an aspartate to asparagine substitution within the putative lysophospholipid acyltransferase domain.
