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

Alterations in water availability and drought events as predicted by climate change
scenarios will increasingly impact natural communities with effects already emerging at …

Abstract Model systems in biology expand the research capacity of individuals and the
community. Closely related to Arabidopsis, the genus Boechera has emerged as an …

Anthocyanins are flavonoid pigments providing plants a range of colors from red, pink,
orange to blue. Anthocyanins are synthesized in the cytosol but accumulate predominantly …

Pigmentation affords resistance to abiotic stressors, and thus can respond adaptively or
plastically to drought and extreme temperatures associated with global change. Plants …

Upland cotton (Gossypium hirsutum L.) is one of the important fiber crops. Cotton flowers
usually appear white (or cream-colored) without colored spots at the petal base, and turn …

Uncovering the role of competition and facilitation in community assembly is central for
developing a predictive understanding of the forces that organize biodiversity. Standard trait …

Floral color polymorphism can provide great insight into species evolution from a genetic
and ecological standpoint. Color variations between species are often mediated by …

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 …

Pollinators are attracted to vibrant flower colors. That is why flower color is the key agent to
allow successful fruit set in food or ornamental crops. However, black flower color is the least …
