Characterization and Variability Analysis of Volatile Metabolites From Acer saccharum Leaves From Québec Region

Chemistry &Biodiversity, Volume 22, Issue 10, October 2025.
ABSTRACT Volatile secondary metabolites in plants can serve as valuable biomarkers for the plant's health, stress response, and pest or disease detection. We have investigated the volatilome of Acer saccharum (sugar maple) leaves using two complementary extraction techniques: headspace‐solid phase micro‐extraction coupled with gas chromatography‐mass ...

Rose Bengal Is a Precise Pharmacological Tool Triggering Chloroplast‐Driven Programmed Cell Death in Plants, Dependent on Calcium and Mitochondria, and Associated With Early Transcriptional Reprogramming

Plant Direct, Volume 9, Issue 10, October 2025.
ABSTRACT Programmed cell death (PCD) mediates plant development and environmental interactions. Photosynthesis‐derived singlet oxygen (1O2) is one of key reactive oxygen species (ROS) implicated in acclimation and PCD responses to environmental stress conditions.

Plastids in a Pinch: Coordinating Stress and Developmental Responses Through Retrograde Signalling

Plant, Cell &Environment, Volume 48, Issue 9, Page 6897-6911, September 2025.
ABSTRACT Plastids are crucial for fuelling and regulating plant growth and development. Photosynthesising chloroplasts provide energy for growth, while other plastids play additional key roles in various aspects of plant physiology. For function and development, plastids greatly depend on nucleus‐encoded proteins, and they can modulate the synthesis of

Integrative Analyses of Metabolome and Transcriptome Reveals Apocarotenoid and Flavonoid Biosynthesis During Saffron (Crocus sativus L.) Stigmas Development

Food Science &Nutrition, Volume 13, Issue 8, August 2025.
During the development of saffron stigmas, crocetin and flavonoids were primarily synthesized in the early red stage (S1), while crocins were synthesized in the late red stage (S2). The biosynthesis pathways of ABA and picrocrocin were particularly active at anthesis (S3).

Adaptation Mechanisms of Drosophila melanogaster and Drosophila suzukii to Their Distinct Habitats

Entomological Research, Volume 55, Issue 8, August 2025.
ABSTRACT The Drosophila genus comprises over 2000 species worldwide, making it a valuable model for studying habitat selection and preference differences among species in specific ecosystems. This review focuses on the differences in habitat and chemical preference between Drosophila melanogaster, which inhabits overripe and decaying fermented fruits ...
