The genome of Eustoma grandiflorum reveals the whole‐genome triplication event contributing to ornamental traits in cultivated lisianthus

Substantial copy number variations of transcriptional factors (TFs) and structural genes participating in flavonoid/anthocyanin biosynthesis were discovered as a result of WGT including MYBs, bHLHs, CHIs, CHSs, DFRs, GTs and FLSs (Figures S9–S15). [...]it was hypothesized that the polyploidy event would enable the breeding of colourful lisianthus varieties by providing enhanced genetic materials for anthocyanin production. [...]we suggested that in lisianthus CHSa, ANSa/b, F3′5′Ha/b, MYB32a/b and MYB8b codetermine blue/violet flower coloration, CHSa and ANSa/b codetermine pink/red flower coloration and CHSa determines yellow flower coloration (Figure 1c). [...]we speculated that AGL1a could be linked to the more apparent double-flower phenotype with more petal numbers of ‘Wavy White’ (Figure S32).
