Archives of Virology, 2016 Groundnut ringspot virus (GRSV) and tomato chlorotic spot virus (TCSV) share biological and serological properties, so their identification is carried out by molecular methods. Their genomes consist of three segmented RNAs: L, M and S. The finding of a reassortant between these two viruses may complicate correct virus identification and requires the ...

First Report of Tomato chlorotic spot virus in the Non-Solanaceous Weeds Erect Spiderling (Boerhavia erecta), Asian Spiderflower (Cleome viscosa), and Sweet Chili Pepper (Capsicum chinense) in Puerto Rico [PDF]
Plant Health Progress, 2017 Tomato chlorotic spot virus (TCSV) has recently been detected in tomato, bell pepper, jimsonweed, and lettuce in Puerto Rico. Observations of weeds and additional crops in 2015 and 2016 revealed TCSV-like symptoms. Testing of these symptomatic plants identified three new hosts of TCSV in Puerto Rico: erect spiderling (Boerhavia erecta); Asian ...

Molecular Plant Pathology, Volume 27, Issue 2, February 2026.Glycoside hydrolase 17 family gene CaGH17‐12 contributes to P. capsici resistance by degrading pathogen‐derived β‐glucans and generating β‐glucan oligosaccharides, thereby triggering downstream JA signalling and ROS‐mediated defence responses. ABSTRACT Glycoside hydrolase family 17 (GH17) plays a critical role in degrading pathogen cell walls and is ...

Molecular mechanisms of plant NLR activation and signalling
The Plant Journal, Volume 125, Issue 3, February 2026.SUMMARY Plants rely on NLRs (nucleotide‐binding leucine‐rich repeat receptors) to recognise effector proteins secreted by pathogens into plant cells and to deliver disease resistance. Plant NLRs are broadly characterised by their N‐terminal domains, which include the TIR (Toll/interleukin‐1 receptor) and the CC (coiled‐coil) domains.

Food and Energy Security, Volume 15, Issue 1, January/February 2026.ABSTRACT Iron (Fe) is an essential micronutrient for plant photosynthesis and human health. Pear represents a widely consumed fruit for human Fe intake, yet its yield and quality are frequently challenged by Fe deficiency (FD) stress. Despite the prevalence of FD stress in agricultural production under generally alkaline and calcareous conditions, pear

Plant Disease, 2014 The Dominican Republic has a significant area of the country cultivated with vegetables. In July 2013, in the provinces of Moca and La Vega, horticultural crops showed typical tospovirus symptoms (>30% incidence), including bronzing, chlorosis, necrosis, and ring spots on leaves and fruits.

Pepino Mosaic Virus: A Globally Important Tomato Pathogen and a Rising Model in Molecular Virology
Molecular Plant Pathology, Volume 27, Issue 1, January 2026.Pepino mosaic virus (PepMV) is a globally important tomato pathogen causing fruit quality losses. It comprises multiple genetic types and spreads via seed and mechanical contact. Lacking resistant cultivars, management relies on cross‐protection. PepMV–tomato interactions provide a valuable model for studying virus–plant molecular mechanisms and ...

The Arabidopsis deNADding Enzyme DXO1 Modulates the Plant Immunity Response
Plant, Cell &Environment, Volume 49, Issue 1, Page 32-50, January 2026.ABSTRACT DXO1, the only DXO homolog in Arabidopsis, due to its plant‐specific features, exhibits strong deNADding enzymatic activity but has no apparent role in 5′ QC. Despite its important contribution to plant RNA metabolism, the direct impact of DXO1 enzymatic activity on cellular processes appears surprisingly limited.
