Natural selection acts on phenotypic trait variation. Understanding the mechanisms that
create and maintain trait variation is fundamental to understanding the breadth of diversity …

Background Pollinators impose strong selection on floral traits. Indeed, pollinator syndromes
are the result of these strong selective forces, but other abiotic and biotic agents also drive …

Understanding the molecular mechanisms and evolutionary process of plant adaptation to
the heterogeneous environment caused by altitude gradients in plateau mountain …

Petal color variation within species is common and may be molded by abiotic or biotic
selection pressures, or neutral population structure. For example, darker flowers may be …

The evolution of flower color, especially petal pigmentation, has received substantial
attention. Less understood is the evolutionary ecology of pollen pigmentation, though it …

Flavonoids are important secondary metabolites that play an integral role in protecting
plants against UV radiation and other forms of environmental stress. Given widespread …

The objective of this study was to get the answer on the question, which phenolic
compounds may serve as chemical markers in taxonomy of Euphrasia spp.(E. nemorosa, E …

Flower colour variation is ubiquitous within and between populations, which is why it has
long been a focal point for studies of natural selection. This body of work has uncovered a …

We present a study of short and long‐term responses of photosynthetic apparatus and anti‐
oxidant capacity to complex abiotic stresses of Calamagrostis epigejos and Solidago …

Rhodiola crenulata (Hook. f. & Thomson) H. Ohba is an alpine medicinal plant that can
survive in extreme high altitude environments. However, its changes to extreme high altitude …
