Drought Stress Mediated Changes in Food Crops: Mechanisms and Remediation Strategies

Advanced Science, EarlyView.
This work presents a multi‐scale framework for flavonoid‐mediated drought tolerance in staple food crops, integrating ROS redox regulation, antioxidant defense, rhizosphere microbial interactions, and sustainable agronomic practices. This interdisciplinary model provides core insights to develop climate‐resilient cropping systems and enhance global ...

Niche‐Mediated Neural Priming Enables Robust and Scalable Generation of Human Choroid Plexus Organoids

Advanced Science, EarlyView.
Compared to E8, mTeSR1 culture downregulated WNT and TGF‑β signaling, and upregulated neural differentiation pathways, enhancing neural priming. Under skin organoid induction conditions, mTeSR1‑cultured hESCs generated organoids with significantly higher neuroepithelial differentiation.

Risk management externalities in agrifood supply chains

American Journal of Agricultural Economics, EarlyView.
Abstract Firms may under‐ or over‐invest in risk management from the social planner's perspective, resulting in a negative externality on other economic agents in the supply chain. The externality of risk management is particularly relevant for agrifood supply chains, which frequently experience disruptions and play a primary role in preventing major ...
