Daily Heat Stress Induces Donor‐Side Limitation of PSI Via Downregulation of the Cyt b6f Complex

Plant, Cell &Environment, EarlyView.
ABSTRACT The rapidly warming climate is driving increasingly frequent and intense heat waves worldwide, posing major challenges to plant metabolism and growth. Despite the central role of photosynthesis in plant growth, the effects of prolonged heat stress on the primary reactions of photosynthesis remain poorly understood.

Design Principles of Plant Thermotolerance: Integrating Photosynthesis, Reproduction, and Field Resilience in a Warming Climate

Plant, Cell &Environment, EarlyView.
ABSTRACT Global food security is increasingly threatened by climate change, as rising temperatures compromise the yields of major staple crops, including wheat, rice, and maize. Enhancing plant thermotolerance has therefore become a critical priority for sustaining agricultural productivity.

Rhizobial Symbiosis Enhances Salinity Tolerance in Legumes Through Coordinated Physiological and Molecular Responses: Evidence From Common Vetch and Pea

Plant, Cell &Environment, EarlyView.
ABSTRACT Soil salinisation severely constrains crop production. Legumes rely on rhizobial symbiosis for sustainable nitrogen acquisition. Although salinity is known to impair nodulation and nitrogen fixation, how symbiosis influences plant tolerance to salt stress remains unclear.

Time‐series multi‐omics analysis of micronutrient stress in Sorghum bicolor reveals iron and zinc crosstalk and regulatory network conservation

Plant Biology, EarlyView.
Overlap between Fe and Zn responsive gene regulatory networks (GRNs) were found, indicative of micronutrient crosstalk, and conservation of root and leaf GRNs and genes suggests strong constraint on homeostasis networks in plants. Abstract Micronutrient stress impacts growth, biomass production, and grain yield in crops.

Feeding spinach thylakoids to rats modulates the gut microbiota, decreases food intake and affects the insulin response

Journal of Nutritional Science, 2013
Thylakoid membranes derived from green leaf chloroplasts affect appetite-regulating hormones, suppress food intake, reduce blood lipids and lead to a decreased body weight in animals and human subjects.

Exogenous IAA application alleviated altered physiological and biochemical processes through promoting H‐ATPase and Fe chelate reductase activities in common bean (Phaseolus vulgaris L.) subjected to iron deficiency

Plant Biology, EarlyView.
Exogenous IAA supply enhances the strategy I response in common bean under iron deficiency. Abstract Iron deficiency is a common nutritional disorder observed in calcareous soils, where its resolution by classical methods has shown its failure. However, the exploitation of certain potentialities possessed by crops (rhizosphere acidification, H‐ATPase ...

Two proteins co‐expressed with photosynthetic regulators affect photosynthetic dynamics linked to changes in thylakoid pigment content and composition

Plant Biology, EarlyView.
Two factors identified by co‐expression analysis of photosynthetic regulators are described, which are involved in thylakoid pigment content and composition and, through their function, shape the dynamics of NPQ. Abstract Rapid fluctuations in light intensity require swift regulatory adjustments of photosynthesis. Although the major plant regulators of

Early‐stage diagnosis of nutrient deficiency by chlorophyll fluorescence in maize

Plant Biology, EarlyView.
Symptomatic differences between nitrogen and magnesium deficiency in maize seedlings can be detected using chlorophyll fluorescence to measure spatiotemporal changes in leaf chlorophyll and epidermal UV‐absorbing compounds for early diagnosis and differentiation of nutrients.
