StuPPO9 Enhances Drought Tolerance in Potato (Solanum tuberosum) by Coordinating Photosynthetic Stability and Secondary Metabolism Reprogramming

Drought stress is a primary abiotic constraint limiting potato productivity. While polyphenol oxidase (PPO) is known to participate in stress responses, the specific role of StuPPO9 in drought tolerance remains poorly understood. In this study, we generated StuPPO9-overexpressing...

Observation–Feedback Closure I (v1.5.0): A Self-Consistent Relational Reconstruction from Directed Processes and Internal Occurrence Arithmetic to Functional Dimensionality and Conditional Geometric, Temporal, and Topological Extensions

This preprint is version v1.5.0 of Observation–Feedback Closure I. It presents a foundational reconstruction and logical restructuring of the OF Closure framework rather than a merely additive extension of v1.4.0. The principal purpose of this version is to repair three foundatio...

Aerobic Denitrification Reactor with Pseudomonas chloritidismutans K14 Improves Water Quality and Growth of Hybrid Grouper (Epinephelus fuscoguttatus ♀ × Epinephelus lanceolatus ♂) in RAS

The intensification of mariculture has increased nitrogen and phosphorus pollution in aquaculture wastewater. Conventional treatments often prove inefficient under saline conditions. To address this challenge, we developed an innovative aerobic denitrification reactor using Pseud...

Gill histological, biochemical and transcriptomic responses of Coregonus ussuriensis to acute salinity stress

Salinity is a key environmental factor affecting the osmoregulation and physiological homeostasis in freshwater fish. Juvenile Coregonus ussuriensis has been considered a candidate species for culture in moderately saline waters, but its short-term physiological and molecular res...
