Endoparasitic Gall Mites: Two New Novophytoptus Species (Eriophyoidea, Phytoptidae) from Southern African Sedges (Cyperaceae, Carex) and New Hypotheses on the Phylogeny of Novophytoptines

open access: yesDiversity, 2023
Eriophyoid mites (Acariformes, Eriophyoidea) are microscopic chelicerates morphologically greatly preadapted to endoparasitism on plants. Members of at least six phylogenetically distant eriophyoid genera from two families homoplastically transitioned to

Morphology and anatomy of the diaspores and seedling of Paspalum (Poaceae, Poales) [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2013
ABSTRACT The knowledge regarding of the diaspore and post-seminal development of Paspalum L. is important for grassland biodiversity conservation, based on their representativeness and genetic improvement of forage. The morphology of the diaspore and the post-seminal development of Paspalum dilatatum Poir. (rhizomatous), P. mandiocanum Trin.

A revised evolutionary history of Poales: origins and diversification [PDF]

open access: yesBotanical Journal of the Linnean Society, 2013
Poales represents more than one third of all monocotyledons (c. 20000 species in 16 families) and constitutes a microcosm of the angiosperms. The extreme variation in species richness among the families of Poales is still not understood: Poaceae includes ~10000 species whereas six families have fewer than ten species.

Nuclear genes, matK and the phylogeny of the Poales [PDF]

open access: yesTAXON, 2018
AbstractPhylogenetic relationships within the monocot order Poales have been well studied, but several unrelated questions remain. These include the relationships among the basal families in the order, family delimitations within the restiid clade, and the search for nuclear single­copy gene loci to test the relationships based on chloroplast loci.

The chloroplast genome sequence of an aquatic plant, Sparganium eurycarpum subsp. coreanum (Typhaceae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
The complete chloroplast genome sequence of Sparganium eurycarpum subsp. coreanum was determined. The genome size was 161,761 bp in length with 36.9% GC content.

The complete mitochondrial genome of upland rice (Oryza sativa) in southwest of China

open access: yesMitochondrial DNA. Part B. Resources, 2019
We sequenced complete mitochondrial genome of upland rice Oryza sativa (Liliopsida: Poales: Poaceae) with length of 444,883 bp. The genome has similar codon usage and gene organization to those of mitogenome reported for other Poales.

Floral Anatomy of Paepalanthoideae (Eriocaulaceae, Poales) and their Nectariferous Structures [PDF]

open access: yesAnnals of Botany, 2007
Eriocaulaceae (Poales) is currently divided in two subfamilies: Eriocauloideae, which comprises two genera and Paepalanthoideae, with nine genera. The floral anatomy of Actinocephalus polyanthus, Leiothrix fluitans, Paepalanthus chlorocephalus, P. flaccidus and Rondonanthus roraimae was studied here. The flowers of these species of Paepalanthoideae are

The complete chloroplast genome of Eriocaulon sexangulare (Eriocaulaceae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
Eriocaulaceae, a family of herbaceous plants in the order Poales, includes some well-known species used in traditional Chinese herbal medicine. The phylogenetic position of Eriocaulaceae in Poales remains controversial.

Positive selection and ancient duplications in the evolution of class B floral homeotic genes of orchids and grasses

open access: yesBMC 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.

Notes on the Pollen Morphology and Phylogeny Restionales and Poales [PDF]

open access: yesGrana, 1985
Abstract Acetolysed pollen of the Restionaceae Centrolepidaceae and allied families were studied by light microscopy, scanning electron microscopy and transmission electron microscopy, with special reference to the structure of the aperture and interapertural walls.
