Abstract:
... A new genus, Caucasoseris, is established to accommodate Prenanthes abietina, a species of hitherto uncertain systematic position distributed in the western Caucasus and northeasternmost Turkey in montane conifer and mixed forests. Agreement has existed that the species belongs somewhere in the Crepidinae or Lactucinae but its morphological features do not match any genus and previous molecular ph ...

In this study, P. longicalyx Y.P.Chen & C.L.Xiang, a new species from southern China, is described and illustrated. Molecular phylogenetic analyses implemented based on two nuclear ribosomal DNA and four plastid DNA regions showed that P. longicalyx is a distinct l ...

Abstract:
... Barbarea, winter-cress, is a genus of 29 species in Brassicaceae, the mustard family, which has emerged as a model for evolution of plant defence and specialised metabolites. Notably, some Barbarea species have evolved the ability to produce triterpenoid saponins as the only ones in Brassicaceae, some of which make plants resistant to important herbivores. Resistance has, however, been lost in a d ...

Abstract:
... Inorganic phosphate (Pi) is essential for plant growth. However, Pi is often limiting in soil. Hence, plants have established several mechanisms of response to Pi starvation. One of the important mechanisms is Pi recycling, which includes membrane lipid remodeling and plastid DNA degradation via catabolic enzymes. However, the involvement of other degradation systems in Pi recycling remains unclea ...

To study the mechanisms behind the origin of this diversity, it is necessary to determine phylogenetic relationships and species boundaries in radiating alpine groups. The genus Dendrosenecio (Asteraceae) is an iconic ...

Abstract:
... Some plants abandoned photosynthesis and developed full dependency on fungi for nutrition. Most of the so-called mycoheterotrophic plants exhibit high specificity towards their fungal partners. We tested whether natural rarity of mycoheterotrophic plants and usual small and fluctuating population size make their populations more prone to genetic differentiation caused by restricted gene flow and/o ...

Our formal morphometric analysis clearly indicates its morphological ...
