Auxin‐Producing Pseudomonas Recruited by Root Flavonoids Increases Rice Rhizosheath Formation through the Bacterial Histidine Kinase Under Soil Drying

Advanced Science, EarlyView.
Drought is a major cause of crop losses across agricultural regions. Rhizosheath formation enhances plant resistance to drought. Polyploids may tolerate stress more effectively through increased interactions with bacteria. However, the contributions of tetraploid rice associated microbiota to rhizosheath formation under soil drying remain unclear ...

Surface‐Exposed Pd Nanocluster Confined within a Ring‐Shaped Polyoxometalate for Selective Hydrogenation

Advanced Science, EarlyView.
A small Pd nanocluster is successfully prepared within a ring‐shaped polyoxometalate via a mild solid‐state reduction process. The resulting surface‐exposed Pd nanocluster functions as a robust heterogeneous reusable catalyst, enabling highly chemoselective hydrogenation of substrates containing multiple reducible functional groups via selective ...

The role of benzylic-allylic hydrogen atoms on the antiradical activity of prenylated natural chalcones: a thermodynamic and kinetic study

Journal of Biomolecular Structure and Dynamics, 2020
Prenylated chalcones are a family of natural chalcones that have been reported to exhibit a high antioxidant activity. In this paper, the density functional calculations are carried out to study, systematically, the antiradical properties of four ...

Integrated Green Biorefinery for the Production of Anthocyanins, Fermentable Sugars, and High Pure Lignin from Miscanthus × giganteus

Advanced Energy and Sustainability Research, EarlyView.
Integrated production of pigments, fermentation sugars, and pure lignin has been investigated for the creation of profitable biorefinery developments. Choline chloride‐based natural deep eutectic solvents possess unique solvent capabilities to interact with plant cell wall components to disintegrate lignin‐carbohydrate complex.

Anti-angiogenic activity of the flavonoid precursor 4-hydroxychalcone. [PDF]

, 2012
Angiogenesis, the growth of new blood vessels, is necessary for cancerous tumors to keep growing and spreading. Suppression of abnormal angiogenesis may provide therapeutic strategies for the treatment of angiogenesis-dependent disorders.

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 ...
