AbstractThe use of herbaria for science and conservation is enabling greatly enhanced scopes and scales of discovery, exploration and protection of biodiversity. The availability of digital, open-access herbarium data is, perhaps counter-intuitively, expanding the use of physical collections by researchers who use digital collections to find specimens and then sample physical collections for multiomics investigations, including genomics, transcriptomics, metabolomics, proteomics and microbiomics.

AbstractAccurately reconstructing the reticulate histories of polyploids remains a central challenge for understanding plant evolution. Although phylogenetic networks can provide insights into relationships among polyploid lineages, inferring networks may be hindered by the complexities of homology determination in polyploid taxa. We use simulations to show that phasing alleles from allopolyploid individuals can improve inference of phylogenetic networks under the multispecies coalescent.
