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.

Expanded application to plant reproductive tissues of a branched DNA probe‐based in situ hybridization method

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Detecting clear tissue‐ and organ‐specific patterns of gene expression is key to understanding the genetic mechanisms that control plant development. In situ hybridization (ISH) of mRNA is one of the most precise, yet most challenging approaches to gene expression assays.

Dual Functions of Dietary Rubber Seed Oil Supplementation: Enriching N‐3 Polyunsaturated Fatty Acids and Enhancing Antioxidant Capacity in Pekin Ducks

open access: yesAnimal Research and One Health, EarlyView.
Dietary RSO supplementation improved growth performance, simultaneously enriched n‐3 polyunsaturated fatty acids (n‐3 PUFA), and enhanced antioxidant capacity in Pekin ducks, which suggested that RSO has the potential to be a novel n‐3 PUFA source and an antioxidant for Pekin ducks to generate animal functional foods.

Amazonian Cyanobacteria as a Source of Bioactive Compounds With Antimicrobial and Cytotoxic Properties

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Cyanobacteria are photosynthetic microorganisms known for producing diverse bioactive compounds. This study explores the bioactivity of extracts and fractions from Amazonian cyanobacteria and their pigment and phenolic compound production. A fraction from Synechococcus sp. CACIAM 05 showed cytotoxicity against hCMEC/D3 and MG‐63 cells.

A Workflow for Selecting, Profiling, and Optimizing Plant Extracts for Cosmetic Applications

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT In response to the growing demand for innovative natural ingredients in cosmetics, this study proposes a structured approach to identifying bioactive plant species available in France. From 1614 species screened for regulatory acceptability and innovation potential, 18 were shortlisted for phytochemical profiling (high‐performance liquid ...
