Revisiting the life cycle of Margalefidinium polykrikoides Group III

Journal of Phycology, EarlyView.
Abstract Dinoflagellates produce cysts as a strategy to withstand environmental stressors, with nutrient depletion generally considered a key trigger for cyst production. Resting cysts are thick‐walled, typically composed of one to several layers, and characterized by a prolonged dormancy period.

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Evidence That Sri Lanka Is the Origin of a Rare Nematode Resistance Gene in Rice

Plant Direct, Volume 10, Issue 7, July 2026.
ABSTRACT Meloidogyne graminicola is a destructive and widespread pest in tropical rice‐growing systems, whereas resistance in Oryza sativa remains exceptionally rare. A major quantitative trait locus (QTL) associated with resistance has previously been identified at the distal end of chromosome 11 in the resistant varieties, LD 24 (Sri Lanka) and KPM ...

Sporangium Exposure and Spore Release in the Peruvian Maidenhair Fern (Adiantum peruvianum, Pteridaceae). [PDF]

PLoS ONE, 2015
We investigated the different processes involved in spore liberation in the polypod fern Adiantum peruvianum (Pteridaceae). Sporangia are being produced on the undersides of so-called false indusia, which are situated at the abaxial surface of the ...

Current Understanding of Cell‐Surface Immune Receptors for MAMPs and Plant Parasites in the Solanaceae Family

Molecular Plant Pathology, Volume 27, Issue 5, May 2026.
Members of the Solanaceae family use diverse cell‐surface receptors to sense microbes and parasites, triggering immune responses that vary across species and cultivars. ABSTRACT Cell‐surface receptors play a central role in plant defence by enabling the perception of microbial signatures upon initial contact, activating immune responses and protecting ...

Insights Into Virus‐Encoded RNA Silencing Suppressors Across Viral Families: A Focus on Viruses Infecting Solanaceae Crops

Physiologia Plantarum, Volume 178, Issue 2, March/April 2026.
ABSTRACT Viral suppressors of RNA silencing (VSRs) are proteins that interfere with antiviral defense mechanisms and enhance infection. For plant viruses, VSRs can be encoded in viral genomes and satellite molecules and play an important role in the virus's life cycle and in overcoming host defenses.
