Floral shape and color impact heat accumulation and thermal stability of the floral microenvironment in a subalpine meadow

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The floral thermal microenvironment impacts plant reproduction through its effects on gametophyte performance and plant–pollinator interactions. Color and shape are axes of floral variation that may mediate floral temperature because they affect the absorption and reflection of solar radiation, but their interactive effects are unclear.

Influence of Rare Earth Elements on Prebiotic Reaction Networks Resembling the Biologically Relevant Krebs Cycle

open access: yesAngewandte Chemie, EarlyView.
Rare earth elements can act as mediators in a prebiotic reaction network, producing various intermediates of the citric acid cycle starting from glyoxylate and pyruvate. The ionic radius and the resulting variation in Lewis acidity has a significant influence on the observed product scope.

Color polymorphism in Anemone coronaria: Correlations with soil, climate, and flowering phenology

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Flower color polymorphism (FCP) is thought to be driven by multiple selection agents. Although widely associated with visual attraction of multiple pollinators, FCP is also often correlated with abiotic factors. We explored the links between abiotic conditions, flowering phenology, and FCP in the winter‐flowering geophyte Anemone ...

Fluorescent Probes Derived from the Polyene Class of Antifungal Drugs Reveal Distinct Localization Patterns and Resistance‐Associated Vacuolar Sequestration in Candida Species

open access: yesAngewandte Chemie, EarlyView.
Fluorescent probes derived from all three clinically used polyene antifungals (amphotericin B, nystatin, and natamycin) enabled direct visualization of distribution in yeast cells of various Candida species. While retaining the ergosterol‐dependent mode of action of their parent drugs, the probes revealed distinct, structure‐specific localization ...

Identification, classification and phylogenetic analysis of bZIP proteins from Theobroma cacao for subsequent studies of resistance to witches' broom disease : S01P02 [PDF]

open access: yes, 2013
Biotic and abiotic stresses are a major factor in decreased production of various cultures around the world. The culture of cacao (Theobroma cacao) has been suffering for many years with one of the diseases that most affect their crops, the witches ...

Selection maintains floral color polymorphism in scarlet paintbrush, Castilleja coccinea, reflecting combined ecological factors

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Evolutionary theory predicts polymorphism should be rare; however, intraspecific variation in floral color is common and can be attributed to genetic drift, plasticity, or variable selection. Examining floral color polymorphism both within contact zones and across a species' range can reveal the mechanisms maintaining this variation ...

From CO2 to C1 Liquid Fuels: Molecular Electrochemical Production of Formic Acid and Methanol

open access: yesAngewandte Chemie, EarlyView.
Sustainable transformation of CO2 into formic acid and methanol is key to circular carbon economies and sustainable energy. These liquid C1 products are high in energy density, easy to store, and serve as hydrogen carriers and feedstocks. Electrochemical CO2 reduction provides a promising route for carbon recycling and renewable energy integration ...
