Genome size variation and whole-genome duplications in the monocot order Poales
Plant Systematics and EvolutionNuclear genome sizes of 54 representative species from 44 genera of the monocot order Poales were investigated by flow cytometry. Small holoploid genomes with

Ecdeiocolea rigens, a new species of Ecdeiocoleaceae (Poales) from Western Australia
Australian Journal of Botany, 2011 The Western Australian plant family Ecdeiocoleaceae includes only three species but DNA data show them as the closest living sister-group of the Poaceae. Ecdeiocoleaceae are wind-pollinated and monoecious; spikes produce separate zones of pistillate and staminate flowers, in acropetal succession.

Anther and pollen development in some species of Poaceae (Poales) [PDF]
Brazilian Journal of Biology, 2010 Anther and pollen development were studied in Olyra humilis Nees, Sucrea monophylla Soderstr, (Bambusoideae), Axonopus aureus P. Beauv., Paspalum polyphyllum Nees ex Trin. (Panicoideae), Eragrostis solida Nees, and Chloris elata Desv. (Chloridoideae). The objective of this study was to characterise, embryologically, these species of subfamilies which ...

New Names and New Combinations of Jarava, Cinna, Coleanthus, Sclerochloa and Graphephorum (Poales)
American Journal of Agriculture and ForestryWhen establishing a new genus, the utilization of incorrect genera or mere synonyms as comparative taxa will inevitably result in the emergence of a new synonym and leading to new taxonomic confusions.

BMC Evolutionary Biology, 2009 Background Positive selection is recognized as the prevalence of nonsynonymous over synonymous substitutions in a gene. Models of the functional evolution of duplicated genes consider neofunctionalization as key to the retention of paralogues.

A phylogenomic assessment of ancient polyploidy and genome evolution across the Poales [PDF]
Genome Biology and Evolution, 2016 Comparisons of flowering plant genomes reveal multiple rounds of ancient polyploidy characterized by large intragenomic syntenic blocks. Three such whole-genome duplication (WGD) events, designated as rho (ρ), sigma (σ), and tau (τ), have been identified in the genomes of cereal grasses.
