This review summarizes all reports on sesquiterpene lactones and their immediate
precursors from the Cichorieae (Lactuceae) tribe of the Asteraceae. A total of 360 …

Gametophytic apomixis (asexual seed formation without syngamy of female and male
gametes) is a highly interesting mechanism for researchers in plant biotechnology, genetics …

Karyotypic change constitutes an important evolutionary mechanism contributing to in
angiosperm diversification and speciation. Comparative analyses of the karyotype usually …

In addition to the classic allopatric model of speciation in which two lineages diverge
through time, a population may “bud off” from an ancestral population and become adapted …

Scorzonera comprises 180–190 species and belongs to the subtribe Scorzonerinae. Its
circumscription has long been the subject of debate and available molecular phylogenetic …

Abstract Soroseris, Stebbinsia, and Syncalathium are three genera of the sunflower family
(Asteraceae) with restricted distributions on high screes of the Tibetan Plateau. We present a …

Knowing the age of lineages is key to understanding their biogeographic history. We aimed
to provide the best estimate of the age of Cichorieae and its subtribes based on available …

The evolution of the karyotype and genome size was examined in species of Crepis sensu
lato. The phylogenetic relationships, inferred from the plastid and nrITS DNA sequences …

The use of DNA sequence data in plant systematics has brought us closer than ever to
formulating well-founded hypotheses about phylogenetic relationships, and phylogenetic …

Although Crepis was the first model plant group in which chromosomal changes were
considered to play an important role in speciation, their chromosome structure and evolution …
