Evolutionary significance of exine ultrastructure in the subfamily Barnadesioideae (Asteraceae) in the light of molecular phylogenetics
(Elsevier Science, 2015-10)
Barnadesioideae (94 species) is the sister subfamily to the rest of the Asteraceae (23,000 species). Pollen grains in this subfamily are structurally and sculpturally distinctive and diverse. Although pollen morphology has ...
Aspectos da ontogenia, ginosporogênese e ginogametogênese em Dasyphyllum brasiliense (Spreng.) Cabrera e Schlechtendalia luzulaefolia Less. (Barnadesioideae-Asteraceae)
(Universidade Federal de Santa MariaBRCiências BiológicasUFSMPrograma de Pós-Graduação em Agrobiologia, 2014-03-14)
Asteraceae has attracted many embryologists because of its high variability of the embryological features. Nevertheless, nothing is known about the embryology of the species basal subfamily, Barnadesioideae. Thus, this ...

Molecular Phylogeny of Chuquiraga (Asteraceae-Barnadesioideae): Infrageneric Classification and Generic Affinities
(American Society of Plant Taxonomists, 2015-02-12)
Chuquiraga is a genus of evergreen shrubs endemic to the arid and semiarid regions of the Andes and southern South America. The genus has been classified into two sections based on its variation in leaf morphology: Chuquiraga ...
Phylogeography and palaeomodelling of Duseniella patagonica (Barnadesioideae), an early-diverging member of Asteraceae endemic to the Argentinean Monte and Patagonia
(Wiley Blackwell Publishing, Inc, 2020-07)
We performed an integrated phylogeographical and palaeoclimatic study of an early-diverging member of Asteraceae,Duseniella patagonica, endemic to Argentina. Chloroplast and nuclear markers were sequenced from 106 ...
Aspectos morfológicos e ecológicos da ginodioicia em Dasyphyllum brasiliense (spreng.) Cabrera (Barnadesioideae, Asteraceae)
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em AgrobiologiaCentro de Ciências Naturais e Exatas, 2017)
Dasyphyllum brasiliense has two sexual systems: monoecious and gynodioecious, being the studied population characterized as gynodioecy, constituted by complete and pistilated individuals. The evolution of this system depends ...
Resolution of deep nodes yields an improved backbone phylogeny and a new basal lineage to study early evolution of Asteraceae
(Academic Press Inc Elsevier Science, 2014-11)
A backbone phylogeny that fully resolves all subfamily and deeper nodes of Asteraceae was constructed using 14 chloroplast DNA loci. The recently named genus Famatinanthus was found to be sister to the Mutisioideae-Asteroideae ...
