Annals of Botany
BACKGROUND AND AIMS Recent studies have documented numerous morphoanatomical variations for the seed coat in Bromeliaceae. However, the structural diversity and character evolution of the embryo within this family remain largely unexplored.

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 ...

Aegilops Tauschii (Poaceae, Poales) Phylogenetic Tree Based on Transcriptomes Sequencing
Acta Botanica Hungarica40 accessions of Aegilops tauschii Coss. specially chosen to present as much of the species variability as possible in such sample were used to build a phylogenetic tree based on transcriptomes sequences. The tree displays subdivision of Ae.

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.

The polysaccharide composition of Poales cell walls
Biochemical Systematics and Ecology, 1999Abstract Monocotyledon families can be divided into two groups depending on the presence (Group A) or absence (Group B) of ferulic acid ester-linked to their unlignified cell walls. The two groups also differ in the major types of non-cellulosic polysaccharides in their unlignified cell walls: in Group A they are glucuronoarabinoxylans (GAXs), and in

Flavonoid evidence and the classification of the anarthriaceae within the poales
Phytochemistry, 1997Abstract A survey of the flavonoids of all seven known species of Anarthria showed the regular presence of myricetin, quercetin and isorhamnetin and traces of kaempferol. Quercetin 5,4′-dimethyl ether was uniquely present in Anarthria laevis , while quercetin 3-methyl ether occurred in A. gracilis .

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

Morphological architecture of Actinocephalus (Koern.) Sano (Eriocaulaceae-Poales)
Flora - Morphology, Distribution, Functional Ecology of Plants, 2008Abstract Actinocephalus exhibits perhaps more diversity in habit than any other genus of Eriocaulaceae. This variation is largely a result of differences in the arrangement of the paraclades. Based on the analysis of stem architecture of all 25 species of Actinocephalus , the following patterns were established: (1) leaf rosette, with no elongated

Loss of the Acetyl-CoA Carboxylase (accD) Gene in Poales
Plant Molecular Biology Reporter, 2012The loss of a gene is a rare genome-shaping event and as such, contributes important information to our understanding of phylogenetic relationships between genes and between species. Deletion of a gene can help to define a lineage. Here, we utilize the deletion of the chloroplast gene encoding the acetyl-CoA carboxylase subunit D (accD) to help us ...
