Plastome phylogenomics and phylogenetic diversity of endangered and threatened grassland species (Poaceae) in a North American tallgrass prairie

摘要: Native grasslands are one of the most endangered ecosystems in North America. In this study, we examined ecological and evolutionary roles threatened (e/t) grasses by establishing robust relationships with other nonthreatened native introduced grass species community. We hypothesized that phylogenomic distribution e/t Illinois would be phylogenetically clustered because closely related vulnerable to same threats have similar requirements for survival. This study presents first time a phylogeny based on complete plastome DNA Poaceae was analyzed phylogenetic diversity analysis. To avoid disturbance populations, extracted from herbarium specimens. Next-generation sequencing (NGS) techniques were used sequence plastid genomes (plastomes). The resulting tree metrics. successfully produced plastomes demonstrating material is practical source genomic studies. strongly supported defined Dichanthelium as separate clade Panicum. metrics revealed clustering species, confirming our hypothesis.
