Pollen morphology of Poaceae (Poales) in the Azores, Portugal
Grana, 2015AbstractThe objective of this study was to expand knowledge on the Poaceae and morphologically describe pollen grains of species occurring in the Azores Archipelago, Portugal. Pollen grains from each species under study were subjected to standard acetolysis, mounting of at least three permanent slides of each species for observations and measurement of

Comparative embryology and taxonomic considerations in Eriocaulaceae (Poales)
Feddes Repertorium, 2010AbstractThe genus concept within Eriocaulaceae is widely discussed because it is mainly based on a small number of floral characteristics of unknown functional and evolutionary significance. The aim of the present work is to comparatively study the embryology of representatives of most genera of Eriocaulaceae to identify relevant features that might ...

The Evolutionary History of the Poales/Restionales: A Hypothesis
Kew Bulletin, 1987The existing hypotheses on the phylogeny of the families of the Poales are reviewed, and the data on which they are based are critically assessed. The results of this assessment are presented as a cladogram. The fossil pollen record of the order is also reviewed, and many of the results are reinterpreted.

Stomata are mobile epidermal valves that regulate CO₂ uptake at the cost of water loss in response to changes in light, CO₂, vapor pressure deficit (VPD), and other signals. Variation in stomatal function across species can have a significant impact on plant function; however, this variation is often examined within major land plant lineages or within ...

Contributions to the floral anatomy of Juncaceae (Poales – Monocotyledons)
Flora - Morphology, Distribution, Functional Ecology of Plants, 2012Abstract Juncaceae are a cosmopolitan family divided into seven genera with a total of about 440 species. The floral anatomy of Juncus and Luzula, the two largest genera, was investigated to provide information for the understanding of the Juncaceae. The anatomical pattern found in both genera is very uniform.

Putative neofunctionalization of a Poales-specific EXO70 clade
Abstract EXO70s are uniquely expanded in land plants compared to all other eukaryotic lineages. The functional implications of this expansion and diversification on the conserved role of EXO70 as a subunit of the octameric exocyst complex have remained ...Molly Bergum +14 more
