Phytosulfokine signalling blocks mycotoxin toxicity in Arabidopsis and mediates suppression of cell death activated by bacterial microbe‐associated molecular patterns

New Phytologist, Volume 249, Issue 5, Page 2515-2530, March 2026.
Summary Fumonisin B1 (FB1) is a mycotoxin that disrupts ceramide biosynthesis and kills plants. Prior activation with bacterial microbe‐associated molecular patterns (MAMPs), such as components of bacterial flagella, effectively suppresses FB1‐induced cell death.

Climate adaptation and functional constraints drive pollen evolution in Apiales

New Phytologist, Volume 249, Issue 5, Page 2574-2587, March 2026.
Summary Pollen grains exhibit remarkable morphological diversity, shaped by selective pressures from environmental factors and mechanical constraints. Here, we investigate macroevolutionary patterns of pollen morphology in Apiales, an order of angiosperms with significant ecological and geographical diversity, to disentangle the roles of climate and ...

Understanding the dynamic nature of plant lipid anabolic and catabolic metabolism is key to sustainable oilseed engineering

New Phytologist, Volume 249, Issue 5, Page 2196-2214, March 2026.
Summary Plant‐derived oils are essential sources of reduced carbon and various fatty acid (FA) structures for food, biofuels, and the oleochemical industry. Despite extensive efforts, engineering mainstream oilseed crops to produce high levels of industrially valuable unusual FAs (UFAs) remains challenging.

Welcome Pathogens: Transient Heat Dampens Immune Responses to Acibenzolar‐S‐Methyl in Apple Plants

Plant, Cell &Environment, Volume 49, Issue 3, Page 1229-1248, March 2026.
ABSTRACT Climate change affects plant‐pathogen interactions, with disease outcome varying depending on the pathosystem and environmental scenario. In Arabidopsis, a thermo‐sensitive module of salicylic acid (SA) signalling makes immunity vulnerable to heat.

The secreted redox sensor roGFP2‐Orp1 reveals oxidative dynamics in the plant apoplast

Plant Biology, Volume 28, Issue 2, Page 359-373, March 2026.
Using the secreted redox biosensor roGFP2‐Orp1, we reveal differences in extracellular (apoplastic) oxidative processes between and within species, depending on cell type and immune signalling. Abstract Specific generation of reactive oxygen species (ROS) is important for signalling and defence in many organisms. In plants, different types of ROS serve

Generalization for both diurnal and nocturnal pollination in the mass‐flowering desert geophyte Nerine laticoma (Amaryllidaceae)

Plant Biology, Volume 28, Issue 2, Page 468-478, March 2026.
Both diurnal and nocturnal pollinators are important in the desert plant Nerine laticoma. Abstract The evolutionary limits to generalization in plant pollination systems are often determined by trade‐offs in which adaptations to one set of flower visitors reduces the effectiveness of another set of visitors.

The tasiR‐ARF pathway in plants: origin, functions, and interplay of miR‐390, tasiRNAs and ARF3

Plant Biology, Volume 28, Issue 2, Page 328-344, March 2026.
Trans‐acting small interfering RNAs that silence a subset of Auxin Response Factors are crucial for plant growth, developmental timing, proper organ patterning, and coping with stress. Abstract Trans‐acting small interfering RNA (tasiRNAs) are a special type of endogenous small RNAs (sRNAs) found only in plants.

Development of a Novel Extracellular Vesicle‐Based Biomarker Approach for Pediatric High‐Grade Glioma

Journal of Extracellular Biology, Volume 5, Issue 2, February 2026.
ABSTRACT Pediatric high‐grade gliomas (pHGGs) account for 20% of childhood brain tumours and are associated with poor survival. Currently, pHGG detection relies on MRI, a costly and time‐consuming procedure. Extracellular vesicles (EVs) carry molecular markers indicative of their cellular origin and can be isolated from various biofluids, offering an ...

A new species of Amphitecna (Bignoniaceae) endemic to the mountain karst forests of southern Mexico

Nordic Journal of Botany, Volume 2026, Issue 2, February 2026.
Amphitecna brevicalyx (Bignoniaceae), a new tree species endemic to Mexico is described and illustrated. Its cauliflorous inflorescences, featuring a single flower per shoot and funnelform corollas without a transverse fold in the throat, place it within the Amphitecna macrophylla group.

Psychotria caraballoensis (Rubiaceae), a new species from northern Luzon, Philippines

Nordic Journal of Botany, Volume 2026, Issue 2, February 2026.
In this paper, we describe and illustrate Psychotria caraballoensis, a new endemic species from the Caraballo Mountain Range, Luzon, Philippines. It is allied to the Subalpina species group sensu Sohmer and Davis (2007), and resembles Psychotria sohotonensis.
