Size of chloroplasts in Arabidopsis mesophyll cells affects jasmonate biosynthesis

open access: yesPlant Biology, EarlyView.
The relationship between chloroplast structure and hormone biosynthesis capacity is poorly understood. This study shows that mutants harbouring giant chloroplasts produce more jasmonic acid upon mechanical stress than wild‐type plants, suggesting that organellar architecture is a previously unrecognized factor associated with plant hormone biosynthesis

Cation (Ca2+ and Mn2+) Partitioning Assays with Intact Arabidopsis Chloroplasts

open access: yesBio-Protocol, 2017
Determination of the relative distribution of Ca2+ and Mn2+ is an important tool for analyzing mutants showing altered levels of calcium and/or manganese transporters in the chloroplast envelope or thylakoid membrane.

On the relationship between Photosystem II thermotolerance and irreversible heat damage in leaves of Rhizophora mangle

open access: yesPlant Biology, EarlyView.
Temperature‐F0 fluorescence curves of Rhizophora mangle leaves demonstrate that Tcrit, the temperature at which F0 begins to rise, is unrelated to tissue necrosis; irreversible leaf damage starts to occur at significantly higher temperatures where fluorescence emission is maximal. Abstract Global temperatures are on the rise and may, together with more

Chitosan‐induced modulation of secondary metabolism and stress tolerance in Salvia rosmarinus under combined drought and heat stress

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 10, Page 5989-6001, 15 August 2026.
Abstract BACKGROUND Abiotic stresses, particularly drought and elevated temperatures, negatively affect plant physiological and metabolic processes. This study investigated the effects of drought, heat, and combined stress on Salvia rosmarinus (rosemary), and evaluated foliar‐applied chitosan as a biostimulant.

Integrated genomic and transcriptomic approaches reveal oxidative stress adaptation mechanisms in a mesotrione‐resistant Amaranthus tuberculatus biotype

open access: yesPest Management Science, Volume 82, Issue 7, Page 6387-6398, July 2026.
Integrated GWAS and transcriptomics in a Canadian waterhemp biotype reveal mesotrione resistance is polygenic and metabolically driven. Significant SNPs and 187 herbicide‐responsive genes point to enhanced redox homeostasis, glutathione‐linked detoxification, lipid/secondary metabolism, and oxidative stress responses. Resistance arises from coordinated,

Fendioxypyracil, a new and systemic PPO‐inhibiting herbicide for X‐spectrum weed control

open access: yesPest Management Science, Volume 82, Issue 7, Page 6794-6807, July 2026.
This graphical abstract presents the discovery and synthesis of PPO herbicide structures with a central pyridine core, showing molecular conformations, dose–response inhibition curves for PPO1 and PPO2, and comparative weed and grass control efficacy of fendioxypyracil versus other herbicides in greenhouse and field trials.

Effects of applying Trichoderma asperellum to rice (Oryza sativa) on phytobiome and plant responses

open access: yesAnnals of Applied Biology, Volume 189, Issue 1, July 2026.
We investigated the effect of dipping at transplanting or post‐transplanting spray application on the root‐associated microbiome or leaf epiphytes via amplicon sequencing, and on plant responses via RNA‐seq. Both root dipping and foliar application with Trichoderma asperellum spore suspension only had a limited impact on the leaf epiphytes and root ...

A multilayered regulatory framework linking cell wall remodelling, redox homeostasis, and metabolic plasticity during leaf development in Arabidopsis thaliana

open access: yesAnnals of Applied Biology, Volume 189, Issue 1, July 2026.
This study proposes a three‐layered regulatory model illustrating the transition from cell wall remodelling to redox homeostasis during leaf maturation. The model integrates structural extensibility (CESA8, XTH15), redox‐metabolic balancing (AOX1A), and transcriptional feedback mediated by NAC13.

Transmission electron microscopy characterisation of Spirulina bioplastics

open access: yesJournal of Microscopy, Volume 303, Issue 1, Page 101-119, July 2026.
Abstract Plastic pollution is impacting global ecosystem health. Bioplastics made from unprocessed biomass, including whole or fragmented tissues, are one potential solution. They are biodegradable and exhibit competitive mechanical performance. Seaweed and microalgae have gained popularity over the last decade as bioplastic feedstocks due to their ...

The unicellular green microalga Botryosphaerella sudetica links plant‐like light protection with an algal lifestyle

open access: yesNew Phytologist, Volume 251, Issue 1, Page 372-383, July 2026.
Summary Nonphotochemical quenching (NPQ) mechanisms fine‐tune light utilisation in the photosynthetic antenna, for example, in response to excess light, to prevent photodamage. NPQ comprises distinct mechanisms, all contributing to photoprotection but acting on different time scales.
