The Involvement of the S2P2 Intramembrane Protease in the Response of Arabidopsis thaliana Chloroplasts to High Light Stress

Plants
High light intensity constitutes a critical abiotic stress factor that profoundly affects the structural and functional integrity of the photosynthetic apparatus.

Soybean Inositol Polyphosphate 5‐Phosphatase 8 Confers Salt Tolerance by Reducing Sodium Influx Through Inositol 1,4,5‐Trisphosphate Signalling

Plant, Cell &Environment, EarlyView.
ABSTRACT Evidence suggests that the metabolism of inositol and its derivatives may be involved in various biological processes including salt tolerance, but there has been limited understanding. Ectopic expression of Gs5PTase8, an inositol polyphosphate 5‐phosphatase cloned from wild soybean (Glycine soja), significantly enhanced salt tolerance in ...

Biogenesis and origin of thylakoid membranes

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2001
Thylakoids are photosynthetically active membranes found in Cyanobacteria and chloroplasts. It is likely that they originated in photosynthetic bacteria, probably in close connection to the occurrence of photosystem II and oxygenic photosynthesis. In higher plants, chloroplasts develop from undifferentiated proplastids.

How Plants May Maintain Protein Homeostasis Under Rising Atmospheric CO2

Plant, Cell &Environment, EarlyView.
ABSTRACT Vascular plants may employ several physiological mechanisms to stabilize their protein contents as atmospheric CO2 concentrations change over a day, year, decade, or century. One mechanism is that plants may rely more on soil ammonium as their nitrogen source when CO2 increases.

Phytohormonal and Transcriptomic Mechanisms of Multigenerational Stress Memory in Wheat Under Weed Competition

Plant, Cell &Environment, EarlyView.
ABSTRACT Multigenerational stress exposure induces stress memory in plants, influencing resource allocation, defence mechanisms, and productivity. Weed competition imposes both resource‐based (abiotic) and allelopathic (biotic) stress, engaging overlapping hormonal pathways.

Loss of qE Does Not Necessarily Lead to Photoinhibition: Sustained Non‐Photochemical Quenching in the Absence of PsbS and Zeaxanthin

Plant, Cell &Environment, EarlyView.
ABSTRACT Photosynthetic light‐harvesting complexes mediate light absorption and energy dissipation. By modulating the photosystems' absorption cross‐section, they affect both photosynthetic activity and non‐photochemical quenching (NPQ). These processes are often studied by spectrally integrated chlorophyll fluorescence, masking their associated ...

Entropy-assisted stacking of thylakoid membranes

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2005
Chloroplasts in plants and some green algae contain a continuous thylakoid membrane system that is structurally differentiated into stacked granal membranes interconnected by unstacked thylakoids, the stromal lamellae. Experiments were conducted to test the hypothesis that the thermodynamic tendency to increase entropy in chloroplasts contributes to ...

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.

Impact of emerging compound droughts on forests: A water supply and demand perspective

Plant Biology, EarlyView.
This review examines the physiological and ecological responses of trees to emerging compound droughts from a water demand and supply perspective, as well as the role of acclimation and consequences for ecosystem‐level functions. Abstract The intensification of climate change‐induced drought results in unprecedented tree and forest die‐offs worldwide ...

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 ...
