The internal transcribed spacers (ITS) of the nuclear ribosomal 18S–5.8 S–26S cistron
continue to be the most popular non-plastid region for species-level phylogenetic studies of …

Fruits are the defining feature of angiosperms, likely have contributed to angiosperm
successes by protecting and dispersing seeds, and provide foods to humans and other …

Dobzhansky stated that nothing in biology makes sense except in the light of evolution. A
close corollary, and the central theme of this paper, is that everything makes a lot more …

A molecular phylogenetic analysis of the Andean genus Tarasa (Malvaceae) and related
genera yielded unexpected results regarding generic boundaries, the origins of polyploidy …

The phylogeny of 116 species and varieties of Pythium was studied using parsimony and
phenetic analysis of the ITS region of the nuclear ribosomal DNA. The D1, D2 and D3 …

Quercus is one of the most abundant and economically important genera of woody plants in
the Northern Hemisphere. To infer phylogenetic relationships within Quercus subgenus …

• Premise of the study: The opuntias (nopales, prickly pears) are not only culturally,
ecologically, economically, and medicinally important, but are renowned for their taxonomic …

To evaluate the monophyly of subtribe Pleurothallidinae (Epidendreae: Orchidaceae) and
the component genera and to reveal evolutionary relationships and trends, we sequenced …

Previous molecular phylogenetic studies have failed to resolve the branching order among
the major cotton (Gossypium) lineages, and it has been unclear whether this reflects actual …

We explore the phylogeny of the polygrammoid ferns using nucleotide sequences derived
from three plastid loci for each of 98 selected species. Our analyses recovered four major …
