Apple Russet Ring and Apple Green Crinkle Diseases: Fulfillment of Koch’s Postulates by Virome Analysis, Amplification of Full-Length cDNA of Viral Genomes, in vitro Transcription of Infectious Viral RNAs, and Reproduction of Symptoms on Fruits of Apple Trees Inoculated With Viral RNAs

Frontiers in Microbiology, 2020
Apple russet ring and apple green crinkle are graft-transmitted diseases first reported more than 60 years ago, but at present, no association between a specific virus (variant) and the disease has been clearly demonstrated.

Cucumber green mottle mosaic virus: A persistent seed‐borne threat to cucurbits

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
Cucumber green mottle mosaic virus (CGMMV) is a highly stable, seed‐borne tobamovirus that threatens global cucurbit production. Its efficient mechanical and seed transmission, long‐term environmental persistence, and the spread of Clade II CGMMV isolates drive its rapid dissemination and cause severe yield losses.

Apple scar skin viroid causes dapple and scar skin apple diseases by disrupting phenylpropanoid‐mediated metabolic pathways

New Plant Protection, Volume 3, Issue 2, June 2026.
Dapple apple and scar skin apple diseases are closely associated with suppression of anthocyanin biosynthesis and enhancement of suberin biosynthesis. Apple scar skin viroid (ASSVd) infection represses anthocyanin biosynthesis in apple callus. Abstract Apple scar skin viroid (ASSVd) causes dapple and scar skin apple diseases, posing serious threats to ...

ICAG‐Net: An Interactive CNN–Transformer Architecture With Attention‐Guided Gated Fusion for Crop Disease Detection

Engineering Reports, Volume 8, Issue 5, May 2026.
This study presents an AI‐driven approach to smart agriculture focused on early detection of crop diseases, especially fungal infections, to enhance food security. An ensemble model combining a Custom CNN for local feature extraction and a pretrained vision transformer (ViT) for global context analysis is proposed.
