Dimorphic flowers growing on a single individual plant play a critical role in extreme adaptation and reproductive assurance in plants and have high ecol. and evolutionary significance. However, the omics bases underlying such a differentiation and maintenance remain largely unknown. We aimed to investigate this through genomic, transcriptome and metabolomic analyses of dimorphic flowers in an alpine biennial, Sinoswertia tetraptera (Gentianaceae). A high-quality chromosome-level genome sequence (903 Mb) was first assembled for S. tetraptera with 31,359 protein-coding genes annotated. Two rounds of recent independent whole-genome duplication (WGD) were revealed. Numerous genes from the recent species-specific WGD were found to be differentially expressed in the two types of flowers, and this may have helped contribute to the origin of this innovative trait. The genes with contrasting expressions between flowers were related to biosynthesis of hormones, floral pigments (carotenoids and flavonoids) and iridoid compounds, which are involved in both flower development and color. Metabolomic analyses similarly suggested differential concentrations of these chems. in the two types of flowers. The expression interactions between multiple genes may together lead to contrasting morphol. and chem. concentration and open vs. closed pollination of the dimorphic flowers in this species for reproductive assurance. In the experiment, the researchers used many compounds, for example, (4aR,5R,6S)-4a-Hydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)-5-vinyl-4,4a,5,6-tetrahydropyrano[3,4-c]pyran-1(3H)-one (cas: 17388-39-5Application of 17388-39-5).
