Lobularia maritima (sweet alyssum) is a popular ornamental plant that displays range of flower colors, particularly white and purple. However, the genetic underpinning evolutionary history colors have remained unknown. To address this, we performed de novo assembly chromosome-level genome for this species conducted comparative population genomic analyses both domestic wild representatives. These revealed distinct clusters corresponding to groups, with further subdivisions based on geographic phenotypic differences. Importantly, all cultivars originated from single domestication event within Tunisia group. One group did not contribute genetically current cultivars. The new mutations in key gene anthocyanin biosynthetic pathway, PAP1, arose following led origin purple coloration Moreover, contrasting PAP1 haplotypes varieties lead differential expression CHS DFR, which turn contributes observed color findings provide insights into regulation L. maritima, laying groundwork future breeding efforts focused plant, especially introducing sources other groups.
