Responsive Membrane Antenna Enables Adaptive Biohybrid Interface for Photosynthesis Promotion, Stress Reporting and Modulation

Advanced Science, EarlyView.
An environmentally responsive antenna assembled onto the algal cell membrane creates a biohybrid with a responsive interface that promotes photosynthesis under normal conditions and shifts to H2O2‐triggered stress reporting and modulation upon stress onset, boosting environmental sensing and adaptive response.

Herbivory‐Induced Stomatal Opening Triggers the Dispersal of an Invasive Insect Herbivore

Advanced Science, EarlyView.
The invasive leafminer Phthorimaea absoluta uniquely manipulates plant defenses by inducing stomatal opening in tomato. This response, mediated by the stomatal regulator IQM1, enhances the release of the repellent volatile benzaldehyde. This volatile triggers the dispersal of adult moths, facilitates colonization of new hosts, and leads to rapid ...

OsCPK12‐OsATPD1 Module Regulates Photosynthetic Acclimation to Light Stress in Rice

Advanced Science, EarlyView.
OsCPK12 interacts and phosphorylates OsAtpD1 at Ser8 in its transit peptide. This phosphorylation promote its chloroplast translocation, thereby maintaining ATP synthase activity and proton gradient (ΔpH) homeostasis and regulating photosynthetic acclimation, photoprotection, and repair under light stress.

Natural‐Inspired Engineered Microalgae With Selenium Enrichment Enabled Potent Anti‐Tumor Immunity

Advanced Science, EarlyView.
Se‐Ssp was engineered as a potent immunomodulator for activating innate immunity via the TLR and cGAS‐STING pathways, therefore converting “cold” tumors into “hot” tumors to achieve high efficacy and long‐term therapeutic outcomes. ABSTRACT Immunotherapy has shed light on clinical oncology for several decades.

Micellar enhanced spectrofluorometric determination of chlorophyll a and chlorophyll b in fresh waters☆

Talanta, 1992
The enhancement of the fluorescence of chlorophyll a and chlorophyll b in a non-ionic micellar media is used for the establishment of a new analytical method for the determination of these pigments. After optimization of the variables, including concentration of surfactant, pH, temperature and percentage of organic solvent, the analytical figures of ...
