Alternaria Mycotoxins in Food and Feed: An Overview

Journal of Food Quality, 2017
Alternaria is one of the major mycotoxigenic fungal genera with more than 70 reported metabolites. Alternaria mycotoxins showed notably toxicity, such as mutagenicity, carcinogenicity, induction of DNA strand break, sphingolipid metabolism disruption, or

Arsenic toxicity: the effects on plant metabolism

Frontiers in Physiology, 2012
The two forms inorganic arsenic, arsenate (AsV) and arsenite (AsIII), are easily taken up by the cells of the plant root. Once in the cell, AsV can be readily converted to AsIII, the more toxic of the two forms.

Rapid dehydration drives a nondiffusional drop in C3 photosynthesis that aligns with phosphate limitation

New Phytologist, Volume 251, Issue 3, Page 1127-1142, August 2026.
Schematic representation of the causal sequence through which rapid water loss imposes diffusive and nondiffusive restrictions on carbon assimilation. Summary Drought is an abnormally prolonged water deficit posing major challenges to plants. Stomatal closure has long been considered the primary factor limiting photosynthesis during the early stages of

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

Plant, Cell &Environment, Volume 49, Issue 8, Page 5401-5420, August 2026.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

Comparison of Proteome Response to Saline and Zinc Stress in Lettuce

Frontiers in Plant Science, 2015
Zinc salts occurring in soils can exert an osmotic stress toward plants. However, being zinc a heavy metal, some more specific effects on plant metabolisms can be forecast.

Effects of dopamine on reducing salt stress damage in pepper (Capsicum annuum L.) at morphological, physiological, biochemical, and molecular levels

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
Salt stress causes oxidative and osmotic stress, resulting in decreased nutrient uptake, plant growth, and photosynthetic rate. This study suggests that foliar application of dopamine can reduce salinity‐induced oxidative damage in pepper plants by altering antioxidant activity, biochemical, and molecular responses.

Photosynthesis regulation impacts carbon and nitrogen assimilation in the diazotrophic cyanobacterium Anabaena sp. PCC 7120

New Phytologist, Volume 251, Issue 1, Page 94-110, July 2026.
Model of intercellular functional coordination in Anabaena. Summary Diazotrophic cyanobacteria fix both atmospheric carbon (C) and nitrogen (N) into biomass, but the two assimilation pathways are not compatible. Species like Anabaena sp. PCC 7120 physically separate C and N assimilation in different cell types.

Response of Chloroplast NAD(P)H Dehydrogenase-Mediated Cyclic Electron Flow to a Shortage or Lack in Ferredoxin-Quinone Oxidoreductase-Dependent Pathway in Rice Following Short-Term Heat Stress

Frontiers in Plant Science, 2016
Cyclic electron flow around PSI can protect photosynthetic electron carriers under conditions of stromal over-reduction. The goal of the research reported in this paper was to investigate the responses of both PSI and PSII to a short-term heat stress in ...

The oxygen‐sensing FixLJ represses nitrogen fixation in Rhodopseudomonas palustris in response to oxygen

mLife, Volume 5, Issue 3, Page 312-324, June 2026.
Abstract Biological nitrogen fixation in symbiotic diazotrophs is subject to oxygen regulation by an oxygen‐sensing FixLJ two‐component system under micro‐oxic conditions. However, it remains unclear whether this mechanism is conserved in free‐living diazotrophs.

A Cross‐Climate Comparison of Molecular Phenology in Three Tropical and Temperate Trees

Plant-Environment Interactions, Volume 7, Issue 2, April 2026.
ABSTRACT Latitudinal gradients in temperature seasonality shape the evolution of thermal tolerance and acclimation capacity in organisms. According to Janzen's climate variability hypothesis, tropical species experiencing stable temperatures evolve narrower thermal niches than temperate counterparts.
