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 ...

Green manure can be an auxiliary factor against dynamic photoinhibition in Dalbergia ecastophyllum (L.) young trees in areas impacted by mining

Photosynthetica
This study evaluated the efficiency of green manure (+GM) on PSII efficiency throughout the day in Dalbergia ecastophyllum. The experiment was carried out in a disabled clay extraction deposit, located approximately 30 km south of São Mateus city ...

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.

A High-Performance and Versatile Fluorometer for Chlorophyll a Monitoring

Biosensors
Chlorophyll a (Chl a) monitoring is vital for aquatic ecosystem assessment but is challenged by low signals and interference. Addressing this, we introduced balanced maximum entropy m-sequence modulation for Chl a fluorescence detection, developing a ...

Chlorophyll Fluorescence Measurements in Arabidopsis Wild-type and Photosystem II Mutant Leaves

Bio-Protocol, 2015
Chlorophyll fluorescence measurement is a widely used technique to determine photosynthetic performance. Light energy absorbed by a chlorophyll molecule can be dissipated by driving photochemical energy conversion, as heat in non-photochemical quenching ...

Investigation the Effects of Salinity and Nitric Oxide on the Changes of Chlorophyll a Fluorescence in Oat (Avena sativa L.) Plant Probed by JIP-Test [PDF]

Zīst/shināsī-i Giyāhī-i Īrān, 2017
Salinity is one of the most important abiotic stresses that affect plant growth and development. In order to study the effects of salinity stress on oat (Avena sativa L.), salinity treatments including 0 (control), 50, 100, and 150 mM sodium chloride and

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.

Defects in leaf carbohydrate metabolism compromise acclimation to high light and lead to a high chlorophyll fluorescence phenotype in Arabidopsis thaliana [PDF]

, 2012
Background: We have studied the impact of carbohydrate-starvation on the acclimation response to high light using Arabidopsis thaliana double mutants strongly impaired in the day- and night path of photoassimilate export from the chloroplast.
