Does the abiotic environment influence the distribution of flower and fruit colors?

American Journal of Botany, EarlyView.
Abstract Premise Color in flowers and fruits carries multiple functions, from attracting animal partners (pollinators, dispersers) to mitigating environmental stress (cold, drought, UV‐B). With research historically focusing on biotic interactions as selective agents, however, it remains unclear whether abiotic stressors impact flower and fruit colors ...

Tracking Structural and Electron Spin Density Changes in a Cooperative Mn3+ Spin Crossover Complex at Atomic Scale via Low Temperature Solid‐State NMR

Angewandte Chemie, EarlyView.
The spin transition of a Mn(III) complex is investigated by tracking the evolution of the 1H and 13C NMR signals of individual sites under fast low‐temperature magic angle spinning conditions. The proposed experimental methodology combined with ab initio calculations of the paramagnetic NMR shifts provides a unique toolbox to study the electronic ...

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

American 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.

Photocatalytic Overall Water Splitting at the Integrated Rh–MoRhOx Cluster Heterostructure on InGaN/GaN Nanowires

Angewandte Chemie, EarlyView.
Integrated Rh–MoRhOx cluster heterostructures on InGaN/GaN nanowires facilitate efficient charge extraction and spatially coupled hydrogen and oxygen evolution reactions, thereby fundamentally accelerating the overall water splitting kinetics. Abstract The quest for efficient solar‐driven water splitting, a promising avenue for clean fuel production ...

Stacked scattering: The key to bright flowers lies in the mesophyll

American Journal of Botany, EarlyView.
Abstract Premise The coloration of flowers is caused by wavelength‐selective absorption by pigments and scattering of light by floral structures. Although the molecular, physiological, and chemical properties of floral pigments have been studied in considerable detail, how floral structures contribute to the visual signal remains largely unknown.
