Heat drastically alters floral color and pigment composition without affecting flower conspicuousness

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Floral pigments primarily serve to attract pollinators through color display and also contribute to protection against environmental stress. Although pigment composition can be plastically altered under stress, its impact on pollinator color perception remains poorly understood.

Temperature and the evolution of flower color: A review

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Flower colors brighten our natural world. How and why have they evolved? How might ongoing global warming alter their evolutionary trajectories? In this review, I examine the influence of ambient temperature on the evolution of flower color.

Exonuclease-fused CRISPR-cas system enhances targeted genome editing for functional genomics in soybean

open access: yesBMC Plant Biology
CRISPR/Cas technologies have revolutionized plant genome editing, yet their inherent bias toward small insertions or deletions (indels) limits their utility for dissecting regulatory elements and generating impactful allelic variants. Here, we report the

Pollinator, herbivore, and climatic selective pressures differ across a floral color transition zone

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Spatial and temporal variations in climate and ecological interactions may underlie the origin and maintenance of floral color polymorphisms across a species range. Betalains are nitrogen‐containing, phylogenetically restricted pigments that, like the widespread and well‐studied anthocyanins and carotenoids, may attract pollinators ...

Intraspecific variation in stomatal architecture, gas exchange, and drought response of a dominant prairie grass sourced from broad climatic gradients

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Understanding how plant populations adapt to water limitation through stomatal traits is key to predicting drought responses. The dominant C4 grass Andropogon gerardi, distributed across sharp climate gradients in North America, offers an excellent focal species to study stomatal architecture (size and density).

Beneficial Effects of Phosphite in Arabidopsis thaliana Mediated by Activation of ABA, SA, and JA Biosynthesis and Signaling Pathways

open access: yesPlants
Phosphite (Phi) has gained attention in agriculture due to its biostimulant effect on crops. This molecule has been found to benefit plant performance by providing protection against pathogens, improving yield and fruit quality as well as nutrient and ...

ttl mutants are impaired in cellulose biosynthesis under osmotic stress [PDF]

open access: yes, 2018
As sessile organisms, plants require mechanisms to sense and respond to the challenging environment, that encompass both biotic and abiotic factors that results in differential development.

Enhanced phenylpropanoid metabolism underlies resistance to Fusarium oxysporum f. sp. vasinfectum race 4 infection in the cotton cultivar Pima-S6 (Gossypium barbadense L.)

open access: yesFrontiers in Genetics
Introduction:Fusarium oxysporum f. sp. vasinfectum (FOV) race 4 (FOV4) is a highly pathogenic soil-borne fungus responsible for Fusarium wilt in cotton (Gossypium spp.) and represents a continuing threat to cotton production in the southwest states of ...
