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

open access: yesNew Phytologist, EarlyView.
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.

Bioconversion of carotenoids into high‐value crocins using a marine sponge carotenoid cleavage dioxygenase

open access: yesNew Phytologist, EarlyView.
Summary Carotenoids and apocarotenoids are widespread specialized metabolites, yet animals, including sponges, lack the ability to synthesize carotenoids de novo and must obtain them from dietary or microbial sources. The roles of carotenoid cleavage dioxygenases (CCDs) in marine animals remain largely unexplored. A CCD from the marine sponge Suberites

Melon seed oil epoxidation: Kinetics and neuro-fuzzy evaluation

open access: yesSouth African Journal of Chemical Engineering
Melon seed oil (MSO) is characterized by unsaturated triglycerides, making it a suitable candidate for epoxidation. This work explored the kinetic and Optimization of MSO epoxidation by the in-situ generation of peroxyacetic acid.

NPF2 is involved in intracellular pH regulation and ion balance in the diatom Phaeodactylum tricornutum

open access: yesNew Phytologist, EarlyView.
Summary Cellular ion and pH homeostasis are crucial factors affecting and regulating metabolic reactions, protein stability, signalling and transport mechanisms. To balance intracellular ion concentrations, organisms need to constantly sense and respond to both the extracellular environment and cell compartments' requests.

Functional divergence of LhcSR and PsbS in zeaxanthin‐mediated non‐photochemical quenching

open access: yesNew Phytologist, EarlyView.
Summary To protect photosystem II from excess light, non‐photochemical quenching (NPQ) dissipates excess energy as heat. NPQ relies on trigger proteins, LhcSR in algae and PsbS in vascular plants, and the light‐regulated xanthophyll cycle, which interconverts violaxanthin and zeaxanthin through the opposite activities of violaxanthin de‐epoxidase and ...

Spatial Regulation of Silicon Accumulation in Peduncle Confers Sheathed Spike in Barley

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Peduncle, the uppermost internode in cereals, connects the stem to the inflorescence and is critical for the transport of water, nutrients and photosynthetic assimilates. While peduncle length associates with plant height and its elongation is primarily regulated by phytohormones, we report a previously unrecognized mechanism involving the ...

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Greener route to 4-vinyl-1-cyclohexane 1,2-epoxide synthesis using batch and continuous reactors

open access: yesGreen Processing and Synthesis, 2014
Polystyrene 2-(aminomethyl)pyridine (Ps.AMP) supported molybdenum (Mo)(VI) complex (Ps.AMP.Mo) was prepared, characterized and assessed as a catalyst for batch and continuous epoxidation of 4-vinyl-1-cyclohexene (4-VCH) using tert-butyl hydroperoxide ...

Spatial and temporal scales in plant phenotyping for crop water stress assessment: A review

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Water stress is a major limiting factor for crop productivity worldwide, and its impacts are intensifying due to climate variability and increasing water scarcity. This review focuses on the spatial and temporal scales in plant phenotyping as a critical approach to improving crop water‐stress assessment and supporting precision water ...
