A haplotype-resolved telomere-to-telomere genome reveals that the bird-shaped turquoise flowers of Strongylodon macrobotrys (jade vine) arise from co-pigmentation between the anthocyanin malvin and the flavonoid saponarin, shaped by genome dynamics and geological event-associated expansions of long terminal repeat retrotransposons.
Liu et al. (Tue,) studied this question.
