Background Domestication modifies the genomic variation of species. Quantifying this
variation provides insights into the domestication process, facilitates the management of …

Natural selection on photosynthetic performance is a primary factor determining leaf
phenotypes. The complex CO 2 diffusion path from substomatal cavities to the chloroplasts …

Herbaceous species can modify leaf structure during the growing season in response to
drought stress and water loss. Evolution can select combinations of traits in plants for …

The Sw-5 gene cluster encodes protein receptors that are potentially able to recognize
microbial products and activate signaling pathways that lead to plant cell immunity. Although …

Abstract Background The Galapagos Islands constitute a highly diverse ecosystem and a
unique source of variation in the form of endemic species. There are two endemic tomato …

After colonization population sizes may vary across the species range depending on
environmental conditions and following colonizations. An interesting question is whether …

Anthocyanins are plant pigments derived from the phenylpropanoid pathway which are
produced in many different species, contributing to defense against stresses by their …

Adaptive evolution requires both raw genetic material and an accessible path of high fitness
from one fitness peak to another. In this study, we used an introgression line (IL) population …

Theory predicts that natural selection should favor coordination between leaf physiology,
biochemistry and anatomical structure along a functional trait spectrum from fast, resource …

Hybridization between closely related plant species is widespread, but the outcomes of
hybridization are not fully understood. This study investigates phylogenetic relationships and …
