A Field‐Based Investigation of the Association Between Cotton Leafroll Dwarf Virus and Bronze Wilt‐Like Responses in Upland Cotton in Georgia

open access: yesPlant Pathology, EarlyView.
In Georgia, commercial upland cotton cultivars that expressed bronze wilt‐like responses consistently showed high copy numbers of cotton leafroll dwarf virus (CLRDV) gene, particularly in late‐planted cotton. These observations parallel historical reports of bronze wilt and suggest an association between CLRDV infection and bronze wilt‐like symptom ...

Novel Microsatellite Markers Reveal Evidence of Sexual Reproduction in Dematophora necatrix Populations From South African Avocado Orchards

open access: yesPlant Pathology, EarlyView.
The study reveals the presence of sexual reproduction in Dematophora necatrix populations from South African avocado orchards through the development of novel microsatellite markers. This finding enhances the understanding of genetic diversity and population structure within these populations, emphasising the significance of alleles and genotype ...

Genome-wide association study identifies quantitative trait loci associated with resistance to Verticillium dahliae race 3 in tomato. [PDF]

open access: yesPlant Genome
Abstract Verticillium wilt (VW) disease, caused by Verticillium dahliae Kleb., is a major threat to tomato (Solanum lycopersicum L.) production. Identifying loci associated with VW resistance can accelerate breeding efforts and support sustainable disease management. Although the Ve1 and Ve2 genes confer resistance to V.

Epidemiological Insights Into Water and Soil‐Mediated Transmission of Tomato Mottle Mosaic Virus

open access: yesPlant Pathology, EarlyView.
Water and growing substrate can serve as reservoirs for tomato mottle mosaic virus (ToMMV) inoculum. ToMMV can survive in water for up to 27 weeks. ToMMV infects bait plants through roots within 5–17 weeks, depending on the severity of root damage. A rapid, field‐deployable RPA test—requiring no RNA extraction—offers sensitivity comparable to RT‐qPCR ...

Citrus breeding for biotic and abiotic stress tolerances; new tools and strategies for biodiversity Mobilization : S04T01 [PDF]

open access: yes, 2013
Citrus industry is affected worldwide by several fungal, bacterial and viral diseases. Some production areas also suffer of strong abiotic constraints such as water deficit, salt stress and iron chlorosis. Resistance or tolerance traits for most of these

An Explainable and Lightweight CNN Framework for Robust Potato Leaf Disease Classification Using Grad‐CAM Visualization

open access: yesApplied AI Letters, Volume 7, Issue 1, February 2026.
Proposed model achieves 99.14% accuracy with near‐perfect precision, recall, and F1 across all classes; Grad‐CAM visualizations confirm focus on biologically relevant symptom‐associated regions. ABSTRACT For identifying foliar diseases in crops at an early stage, accurate detection is necessary in maintaining food security, minimizing economic losses ...
