Structural and Functional Validation of Pseudomonas Savastanoi Ethylene Forming Enzymes Reveals Flexibility in 2‐Oxoglutarate Binding Mode and Conformation

open access: yesChemBioChem, Volume 27, Issue 5, 13 March 2026.
Studies with naturally occuring variants of the Pseudomonas savastanoi ethylene‐forming enzyme (PsEFE) inform on the effect of residues on turnover and product ratio. Crystallographic studies imply a potential for metal ion sensing. Pseudomonas savastanoi pv.

Exogenous melatonin suppresses dark-induced leaf senescence by activating the superoxide dismutase-catalase antioxidant pathway and down-regulating chlorophyll degradation in excised leaves of perennial ryegrass (Lolium perenne L.)

open access: yesFrontiers in Plant Science, 2016
Leaf senescence is a typical symptom in plants exposed to dark and may be regulated by plant growth regulators. The objective of this study was to determine whether exogenous application of melatonin (N-acetyl-5-methoxytryptamine) suppresses dark-induced

Desulfovibrio‐Hydrogen Sulfide Mediates Capsaicin‐Induced Oxidative Stress and Gut Inflammation via TXNIP/NLRP3 Pathway

open access: yesFood Bioengineering, Volume 5, Issue 1, Page 152-167, March 2026.
ABSTRACT The intake of capsaicin can disrupt the gut microecology and impact health, yet its underlying mechanism is not fully elucidated. This study, by establishing capsaicin‐induced human microbiota‐associated (HMA) mouse models revealed the molecular mechanism by which capsaicin perturbs the gut microbiota and metabolites, leading to intestinal ...

Effects of High Lithium Concentrations on the Growth, Biomass, Mineral Accumulation, Oxidative Stress, Antioxidant and Gene Expression Response, and DNA Methylation in Sunflower Plants

open access: yesPlants
This study demonstrates that sunflower plants display integrated, multilevel responses to excessive lithium (Li) exposure. Li concentrations above 5 mM markedly impair germination, growth, and biomass accumulation. Li is preferentially accumulated in the

Jasmonates enhance plants tolerance grown in Cd‐contaminated environments: A comprehensive overview

open access: yesAnnals of Applied Biology, Volume 188, Issue 2, Page 390-405, March 2026.
Jasmonates (JAs) enhance plant tolerance to cadmium (Cd) stress by activating antioxidant defences but may reduce Cd uptake, limiting their effectiveness for phytoremediation. This review compiles studies that evaluated the effects of JA application on plants grown in Cd‐contaminated environments. Abstract Cadmium (Cd) is a toxic heavy metal and one of

Paraquat pretreatment alters antioxidant enzyme activity and protects chloroplast ultrastructure in heat-stressed cucumber leaves

open access: yesBiologia Plantarum, 2011
Cucumis sativus L. seedlings were pretreated 1 h with 10 μM paraquat (PQ) and then were subjected to normal (25/18 °C) or elevated (42/38 °C) temperature to investigate whether PQ can protect plants against heat stress.

A GLUTAMATE CYSTEINE LIGASE Gene StGSH1 Regulated by StERF10 Enhanced Glutathione Accumulation and Adaptation to Low Phosphorus Stress in Potato

open access: yesAdvanced Science, Volume 13, Issue 8, 9 February 2026.
The StERF10‐StGSH1 module coordinates glutathione (GSH) biosynthesis under low‐phosphorus stress. The low‐phosphate‐induced AP2/ERF transcription factor StERF10 directly activates the transcription of StGSH1 and enhances GSH accumulation. Consequently, GSH scavenges reactive oxygen species and provides sulfur for sulfolipid synthesis, facilitating the ...
