Other claims from this paper (10)
- Method / resource Orchidantha insularis genome annotation yielded 31 541 protein-coding genes.
- Observation Phylogenomic analysis places Orchidantha insularis within the banana group of Zingiberales.
- Observation Orchidantha insularis diverged from Musaceae approximately 65 Ma.
- Observation A shared recent whole-genome duplication is inferred for Orchidantha insularis and Musaceae.
- Observation Orchidantha insularis shows significant expansions in gene families related to photosynthesis and carbon fixation.
- Observation Complete biosynthetic pathways for dimethyl disulfide and indole were revealed in Orchidantha insularis.
- Mechanism Expansions of flavin-containing monooxygenase genes are inferred to reinforce indole metabolism in Orchidantha insularis.
- Observation Signatures of positive selection were found in Orchidantha insularis.
- Observation Whole-genome resequencing of Orchidantha insularis populations revealed high genetic differentiation and low nucleotide diversity.
- Observation Demographic inference indicates severe Pleistocene bottlenecks followed by continued population decline in Orchidantha insularis.
