Long-read sequencing uncovers the adaptive topography of a carnivorous plant genome

Our carnivorous bladderwort genome paper came out today in PNAS!

“Carnivorous plants capture and digest animal prey for nutrition. In addition to being carnivorous, the humped bladderwort plant, Utricularia gibba, has the smallest reliably assembled flowering plant genome. We generated an updated genome assembly based on single-molecule sequencing to address questions regarding the bladderwort’s genome adaptive landscape. Among encoded genes, we segregated those that could be confidently distinguished as having derived from small-scale versus whole-genome duplication processes and showed that conspicuous expansions of gene families useful for prey trapping and processing derived mainly from localized duplication events. Such small-scale, tandem duplicates are therefore revealed as essential elements in the bladderwort’s carnivorous adaptation.” Read the entire manuscript here.
