Abstract Circumscriptions of and relationships among many genera and suprageneric taxa of the diverse grass tribe Poeae remain controversial. In an attempt to clarify these, we conducted phylogenetic analyses of >2400 new DNA sequences from two nuclear ribosomal regions (ITS, including internal transcribed spacers 1 and 2 and the 5.8S gene, and the 3’-end of the external transcribed spacer (ETS)) and five plastid regions (matK, trnL–trnF, atpF–atpH, psbK–psbI, psbA–rps19–trnH), and of more than… 

Phylogeny and biogeography of Calamagrostis (Poaceae: Pooideae: Poeae: Agrostidinae), description of a new genus, Condilorachia (Calothecinae), and expansion of Greeneochloa and Pentapogon (Echinopogoninae)

The molecular data suggest that hybridization and genomic introgression played a prominent role in the evolutionary history of Calamagrostis and a new genus, Condilorachia is proposed.

Advances in the phylogeny of the South American cool-season grass genus Chascolytrum (Poaceae, Pooideae): a new infrageneric classification

The use of single-copy nuclear genes and morphological data for future phylogenetic reconstructions encompassing Chascolytrum is highlighted and the new infrageneric classification proposed for the group under the genus Briza is discussed.

Biogeography, timing, and life‐history traits in the PPAM clade: Coleanthinae (syn. Puccinelliinae), Poinae, Alopecurinae superclade, Miliinae, and Avenulinae and Phleinae (Poaceae, Pooideae, Poeae)

A biogeographic analysis of the PPAM clade of Poeae Plastid DNA Group 2, which includes 12 subtribes of C3 grasses, suggests that alpine and subalpine habitats were ancestral and high tolerance of saline and alkaline conditions arose between the Pliocene and Pleistocene.

A phylogeny of species near Agrostis supporting the recognition of two new genera, Agrostula and Alpagrostis (Poaceae, Pooideae, Agrostidinae) from Europe

Two new genera are described and a key separating Agrostula and Alpagrostis from Agrostis s.s. nov. is provided, that separates into two clades corresponding to A.Agrostis and A.subg.Vilfa.

Phylogeny, morphology and the role of hybridization as driving force of evolution in grass tribes Aveneae and Poeae (Poaceae)

It became evident, that many morphological characters show a very high degree of homoplasy and are seemingly able to change within comparatively short timespans in the evolution of the authors' grasses.

Molecular phylogenetic analysis resolves Trisetum (Poaceae: Pooideae: Koeleriinae) polyphyletic: Evidence for a new genus, Sibirotrisetum and resurrection of Acrospelion

To investigate the evolutionary relationships among the species of Trisetum and other members of subtribe Koeleriinae, a phylogeny based on DNA sequences from four gene regions (ITS, rpl32‐trnL

New combinations and updated descriptions in Podagrostis (Agrostidinae, Poaceae) from the Neotropics and Mexico

Abstract Based on morphological study and corroborated by unpublished molecular phylogenetic analyses, five grass species of high-mountain grasslands in Mexico, Central and South America,

A 250 plastome phylogeny of the grass family (Poaceae): topological support under different data partitions

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.

Phylotranscriptomics Resolves the Phylogeny of Pooideae and Uncovers Factors for Their Adaptive Evolution

Molecular evolutionary analyses homologs of CBF for cold resistance uncovered tandem duplications during the core Pooideae history, dramatically increasing their copy number and possibly promoting adaptation to cold habitats.

Phylogenetics of the Grass _Aveneae-Type Plastid DNA Clade_ (Poaceae: Pooideae, Poeae) Based on Plastid and Nuclear Ribosomal DNA Sequence Data

P phylogenetic analyses of plastid trnL-F and nuclear ribosomal ITS DNA sequence data were conducted to infer phylogenetic relationships among and within the five subtribes of the Aveneae-type plastids DNA clade of Poaceae tribe Poeae, finding that AveneAE and Poeae s.s. are not monophyletic in any of their traditional circumscriptions.

Duthieeae, a new tribe of grasses (Poaceae) identified among the early diverging lineages of subfamily Pooideae: molecular phylogenetics, morphological delineation, cytogenetics and biogeography

Morphological, cytogenetic and biogeographical analyses point to warm and humid conditions as the ancestral bioclimatic niche of Phaenosperma and Duthieeae, whereas adaptation to cold and drought occurred only in a part of DuthIEeae but was obviously less successful than in the widespread and much more species-rich tribe Stipeae.

Generic realignments in the grass tribe Aveneae (Poaceae).

None of the new generic alignments is in conflict with morphological and anatomical data that were the only basements of previous classifications and had led to a long-standing controversy in the taxonomy of these oats and the genus Avena.

Molecular diversity and physical mapping of 5S rDNA in wild and cultivated oat grasses (Poaceae: Aveneae).

The "uncommon" 5S gene sequences detected in some Aveneae are not necessarily nonfunctional as pseudogenes because the essential features of the internal control region are maintained even after such duplication events.

A PRELIMINARY PHYLOGENETIC ANALYSIS OF THE GRASS SUBFAMILY POOIDEAE (POACEAE), WITH ATTENTION TO STRUCTURAL FEATURES OF THE PLASTID AND NUCLEAR GENOMES, INCLUDING AN INTRON LOSS IN GBSSI

The results support a novel set of relationships among Ihe tribes of Pooideae, including the placement of Brachypodieae, Bromeae, Triticeae, and Poeae s.l. within a clade for which a three-nucleotide inversion in ndhF is interpreted as a synapomorphy.

Phylogenetic relationships in subtribe Poinae (Poaceae, Poeae) based on nuclear ITS and plastid trnT-trnL-trnF sequences

Generic boundaries and relationships among genera of Poinae using nuclear ribosomal internal transcribed spacer data (ITS) and plastid trnT–trnL-trnF (TLF) sequence data are explored.

Phylogeny of the tribe Aveneae (Pooideae, Poaceae) inferred from plastid trnT-F and nuclear ITS sequences.

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.

Polyphyly of the grass tribe Hainardieae (Poaceae: Pooideae): identification of its different lineages based on molecular phylogenetics, including morphological and cytogenetic characteristics

Support is given for the abandonment of tribe Hainardieae and argue to abandon Poeae subtribe Scribneriinae, which are both highly polyphyletic and phylogenetically distant.

Molecular phylogenetics of Caryophyllales based on nuclear 18S rDNA and plastid rbcL, atpB, and matK DNA sequences.

Two additional lineages are potentially appropriate to be elevated to the family level in the future: the genera Lophiocarpus and Corbichonia form a well-supported clade on the basis of molecular and chemical evidence, and Limeum appears to be separated from other Molluginaceae based on both molecular and ultrastructural data.

Phylogenetic investigation and divergence dating of Poa (Poaceae, tribe Poeae) in the Australasian region

Poa has diversified within the last 4.3 Mya, with divergence dating results broadly congruent with fossil data that record the appearance of vegetation with a prominent grassland understorey or shrubland/grassland mosaic vegetation dating from the mid-Pliocene.
