Evolutionary relationships in Panicoid grasses based on plastome phylogenomics (Panicoideae; Poaceae) [PDF]

open access: yes, 2016
Background: Panicoideae are the second largest subfamily in Poaceae (grass family), with 212 genera and approximately 3316 species. Previous studies have begun to reveal relationships within the subfamily, but largely lack resolution and/or robust ...

Pangenomic Definition of Prokaryotic Species and the Phylogenetic Structure of Prochlorococcus spp.

open access: yesFrontiers in Microbiology, 2018
The pangenome is the collection of all groups of orthologous genes (OGGs) from a set of genomes. We apply the pangenome analysis to propose a definition of prokaryotic species based on identification of lineage-specific gene sets.

First record of Physyphora alceae (Preyssler, 1791) (Diptera, Ulidiidae) from a forensic case in Northern Italy: description of immature stages, DNA barcoding and phylogenetic analysis

open access: yesThe European Zoological Journal, 2021
In forensic entomology the estimation of the minimum postmortem interval and any other evaluation depend on the accuracy of the species identification. Despite the most common species received a lot of attention in the last years, other species belonging

Coming to America: Multiple Origins of New World Geckos [PDF]

open access: yes, 2011
Geckos in the Western Hemisphere provide an excellent model to study faunal assembly at a continental scale. We generated a time-calibrated phylogeny, including exemplars of all New World gecko genera, to produce a biogeographic scenario for the New ...

Cowpox virus: What’s in a Name?

open access: yesViruses, 2017
Traditionally, virus taxonomy relied on phenotypic properties; however, a sequence-based virus taxonomy has become essential since the recent requirement of a species to exhibit monophyly.

Waves of genomic hitchhikers shed light on the evolution of gamebirds (Aves: Galliformes) : research article [PDF]

open access: yes, 2007
Background The phylogenetic tree of Galliformes (gamebirds, including megapodes, currassows, guinea fowl, New and Old World quails, chicken, pheasants, grouse, and turkeys) has been considerably remodeled over the last decades as new data and analytical ...

Going nuclear: gene family evolution and vertebrate phylogeny reconciled [PDF]

open access: yes, 2002
Gene duplications have been common throughout vertebrate evolution, introducing paralogy and so complicating phylogenctic inference from nuclear genes.

Phylogeny of some species of Astragalus (Fabaceae) based on morphological data

open access: yesیافته‌های نوین در علوم زیستی, 2020
The phylogenetic relationships among 39 species belonging to 12 sections of Astragalus from Iran were studied on the basis of 29 morphological characters. The cladistics analysis of the morphological data was performed using PAUP* 4.0b10 program.
