Phylogeny of the festucoid grasses of subtribe Loliinae and allies (Poeae, Pooideae) inferred from ITS and trnL-F sequences.
TLDR
Parsimony and Bayesian analyses of the combined ITS/trnL-F dataset show Loliinae to be monophyletic but unresolved for a weakly supported clade of 'broad-leaved Festuca,' while Vulpia is polyphyletic within the 'fine-leaves' fescues as revealed by the two genome analyses.
Dated historical biogeography of the temperate Loliinae (Poaceae, Pooideae) grasses in the northern and southern hemispheres.
TLDR
Bayesian estimates of divergence and dispersal-vicariance analyses indicate that the broad-leaved and fine-leaves Loliinae likely originated in the Miocene in the panMediterranean-SW Asian region and then expanded towards C and E Asia from where they colonized the New World.
Phylogeny of the tribe Aveneae (Pooideae, Poaceae) inferred from plastid trnT-F and nuclear ITS sequences.
TLDR
This work proposes to expand Poeae to include all the aforementioned lineages of the Aveneae-Poeae-Seslerieae complex through Bayesian- and maximum parsimony-based analyses, separately and in combination.
Phylogeny of Poaceae subfamily Pooideae based on chloroplast ndhF gene sequences.
TLDR
Phylogenetic analyses of the data render a monophyletic Pooideae clade and provide an evolutionary hypothesis for all its tribes and show character changes found within the sequenced nucleotide positions of the ndhF gene to be informative at lower hierarchical levels (genus and species) for some tribes.
The undiagnosed cases of Clostridium difficile infection in a whole nation: where is the problem?
TLDR
CDI was underdiagnosed in diarrhoeic stools in a high proportion of episodes, owing to the use of non-sensitive techniques or lack of clinical suspicion, particularly in people aged <65 years or patients with community-acquired diarrhoea.
Exploiting the Brachypodium Tool Box in cereal and grass research.
TLDR
It is suggested that there remains an urgent need to employ reverse genetic and functional genomic approaches to identify the functionality of key genetic elements, which could be employed subsequently in plant breeding programmes; and a requirement for a Pooideae reference genome to aid assembling large pooid genomes.
Evolution and taxonomic split of the model grass Brachypodium distachyon.
TLDR
The substantial phenotypic, cytogenetic and molecular differences detected among the three B. distachyon sensu lato cytotypes are indicative of major speciation processes within this complex that allow their taxonomic separation into three distinct species.
Phylogeny of Broad-leaved and Fine-leaved Festuca Lineages (Poaceae) based on Nuclear ITS Sequences
TLDR
A new nomenclatural combination is proposed (Festuca arundinacea Schreb + Festuca-Aulaxyper + Vulpia), which is formed by a paraphyletic assemblage of sectional groups, where sects.
Late Cretaceous–Early Eocene origin of yams (Dioscorea, Dioscoreaceae) in the Laurasian Palaearctic and their subsequent Oligocene–Miocene diversification
TLDR
Fossil-informed biogeographical analysis supported colonization of the Nearctic by ancient yam lineages from the western Palaearctic and subsequent migration to the South and possible dispersal to South America via the Eocene North Atlantic Land Bridge.
Extensive gene content variation in the Brachypodium distachyon pan-genome correlates with population structure
TLDR
The data suggest that differentially present genes contribute substantially to phenotypic variation within a eukaryote species, these genes have a major influence in population genetics, and transposable elements play a key role in pan-genome evolution.
