Hydatellaceae identified as a new branch near the base of the angiosperm phylogenetic tree
TLDR
It is shown that Hydatellaceae, a small family of dwarf aquatics that were formerly interpreted as monocots, are instead a highly modified and previously unrecognized ancient lineage of angiosperms, indicating that water lilies are part of a larger lineage that evolved more extreme and diverse modifications for life in an aquatic habitat than previously recognized.
Robust Inference of Monocot Deep Phylogeny Using an Expanded Multigene Plastid Data Set
TLDR
Despite substantial variation in the overall rate of molecular evolution among lineages, inferred amounts of change among codon-position data partitions are correlated with each other across the monocot tree, consistent with low incongruence between these partitions.
A 250 plastome phylogeny of the grass family (Poaceae): topological support under different data partitions
TLDR
resolution of these and other critical branch points in the phylogeny of Poaceae will help to better understand the selective forces that drove the radiation of the BOP and PACMAD clades comprising more than 99.9% of grass diversity.
A molecular phylogeny and new subgeneric classification of Sporobolus (Poaceae: Chloridoideae: Sporobolinae)
TLDR
The phylogenetic analysis provides weak to moderate support for a paraphyletic Sporobolus that includes Calamovilfa, Crypsis, Spartina, and Thellungia, and the molecular results support the recognition of 11 sections and 11 subsections.
Molecular phylogenetics of cool-season grasses in the subtribes Agrostidinae, Anthoxanthinae, Aveninae, Brizinae, Calothecinae, Koeleriinae and Phalaridinae (Poaceae, Pooideae, Poeae, Poeae
TLDR
Deep branches in the combined plastid and combined ITS+ETS trees are generally well resolved, the trees are congruent in most aspects, branch support across the trees is stronger than in trees based on only ITS and fewer plastID regions, and there is evidence of conflict between data partitions in some taxa.
DNA Barcoding the Canadian Arctic Flora: Core Plastid Barcodes (rbcL + matK) for 490 Vascular Plant Species
TLDR
DNA barcodes for the core plastid barcode loci were generated for 490 vascular plant species, representing nearly half of the Canadian Arctic flora and 93% of the flora of theCanadian Arctic Archipelago.
Plastid phylogenomics of the cool-season grass subfamily: clarification of relationships among early-diverging tribes
TLDR
Most aspects of deep relationship in Pooideae are maximally supported in analyses, including those among early-diverging tribes.
(2332) Proposal to conserve the name Sporobolus against Spartina, Crypsis, Ponceletia , and Heleochloa ( Poaceae : Chloridoideae : Sporobolinae )
TLDR
This poster presents a probabilistic assessment of the phytochemical properties of the fruit fly, which has the potential to provide clues to the origin of infectious disease and its mode of transmission.
Using herbarium-derived DNAs to assemble a large-scale DNA barcode library for the vascular plants of Canada1
TLDR
The promise and challenges of using herbarium collections for building a DNA barcode reference library for the vascular plant flora of Canada are demonstrated and an observed decline in sequence recovery with specimen age is associated with poor primer matches, intragenomic variation, or inhibitory secondary compounds in some taxa.
Non-native vascular flora of the Arctic: Taxonomic richness, distribution and pathways
TLDR
In several Arctic regions there are no naturalized non-native taxa recorded and the majority of Arctic regions have a low number of naturalized taxa.
