Proteome and Ubiquitinome Analyses Reveal the Involvement of Ubiquitination in Resistance to Maize Lethal Necrosis

Molecular Plant Pathology, Volume 26, Issue 9, September 2025.
This study analysed the proteome and ubiquitinome of SCMV‐ and/or MCMV‐infected maize plants and demonstrated the role of ZmGOX1 in the maize response to viral infections. ABSTRACT The co‐infection of maize chlorotic mottle virus (MCMV) and sugarcane mosaic virus (SCMV) causes maize lethal necrosis (MLN), which seriously affects the yield and quality ...

Variability of the stomata among 'Albariño' (Vitis vinifera L.) clones and its relationship with susceptibility to downy mildew [PDF]

, 2011
In grapevines the stomata are located on the abaxial epidermis of the leaves, arranged in no specific order. As in other plants, they regulate the communication between the internal tissues and the external atmosphere, playing a critical role in both ...

A Smart Camera With Integrated Deep Learning Processing for Disease Detection in Open Field Crops of Grape, Apple, and Carrot

Journal of Field Robotics, Volume 42, Issue 5, Page 2062-2075, August 2025.
ABSTRACT Downy mildew (Plasmopara), apple scab (Venturia inaequalis), and Alternaria leaf blight are endemic diseases that affect crops worldwide. The diseases can cause severe losses in grapes, apples and carrots when not detected and treated in an early stage.

A β-1,3 Glucan Sulfate Induces Resistance in Grapevine against Plasmopara viticola Through Priming of Defense Responses, Including HR-like Cell Death

Molecular Plant-Microbe Interactions, 2008
Sulfated laminarin (PS3) has been shown previously to be an elicitor of plant defense reactions in tobacco and Arabidopsis and to induce protection against tobacco mosaic virus. Here, we have demonstrated the efficiency of PS3 in protecting a susceptible

RNAi Strategies Against Downy Mildews: Insights Into dsRNA Uptake and Silencing

Molecular Plant Pathology, Volume 26, Issue 8, August 2025.
Use of dsRNA to target genes in downy mildews by co‐applying with inoculum. Pathogen development was assessed via visual scoring, molecular tools and microscopy. This supports gene function studies and disease control strategies. ABSTRACT Downy mildew (DM) diseases are caused by destructive obligate pathogens with limited control options, posing a ...
