Lettuce Chlorosis Virus Disease: A New Threat to Cannabis Production

open access: yesViruses, 2019
In a survey conducted in Cannabis sativa L. (cannabis) authorized farms in Israel, plants showed disease symptoms characteristic of nutrition deprivation. Interveinal chlorosis, brittleness, and occasional necrosis were observed in older leaves.

Next-Generation Sequencing Combined With Conventional Sanger Sequencing Reveals High Molecular Diversity in Actinidia Virus 1 Populations From Kiwifruit Grown in China

open access: yesFrontiers in Microbiology, 2020
Kiwifruit (Actinidia spp.) is native to China. Viral disease–like symptoms are common on kiwifruit plants. In this study, six libraries prepared from total RNA of leaf samples from 69 kiwifruit plants were subjected to next-generation sequencing (NGS ...

Resistance to Grapevine leafroll associated virus-2 is conferred by post-transcriptional gene silencing in transgenic Nicotiana benthamiana [PDF]

open access: yes, 2018
Grapevine leafroll-associated virus-2 (GLRaV-2) is an important component of the leafroll disease complex in grapevine. We have previously sequenced the GLRaV-2 genome and identified the coat protein (CP) gene.

Revealing hidden viruses inducing similar yellowing symptoms or remaining asymptomatic in cucurbit crops

open access: yesPlant Pathology, Volume 74, Issue 1, Page 270-282, January 2025.
Cucurbit aphid‐borne yellows virus (CABYV), watermelon mosaic virus (WMV) and Pepo aphid‐borne yellows virus (PABYV) were the most prevalent viruses affecting melon and watermelon crops across three major producing areas in Spain. Abstract Mixed viral infections occur frequently in plants, leading to diseases that can be difficult to diagnose ...

Aerial low‐altitude remote sensing and deep learning for in‐field disease incidence scoring of virus yellows in sugar beet

open access: yesPlant Pathology, Volume 73, Issue 9, Page 2310-2324, December 2024.
UAVs and CNNs show promise in automating disease scoring in sugar beets, offering efficiency and objectivity, but human expertise remains crucial for validation, especially for subtle disease symptoms. Abstract This study investigates the potential of high‐resolution (<0.5 cm/pixel) aerial imagery and convolutional neural networks (CNNs) for disease ...

Defense strategies against sweet potato chlorotic stunt and pakakuy virus coinfection unraveled

open access: yesCrop Science, Volume 64, Issue 6, Page 3438-3460, November/December 2024.
Abstract This study into the response of two Ipomoea batatas (L.) Lam cultivars, Melinda and Tio Joe, to coinfection with sweet potato chlorotic stunt virus (SPCSV) and sweet potato pakakuy virus (SPPV), employed a comprehensive approach encompassing symptomatology, real‐time quantitative polymerase chain reaction, metagenomics, and transcriptomics ...

Inability of the brown citrus aphid (Toxoptera citricida) to transmit citrus psorosis virus under controlled conditions [PDF]

open access: yes, 2020
Might Toxoptera citricida (BrCA) be a citrus psorosis virus (CPsV) vector? We examined CPsV transmission by the BrCA throughout two experiments. In experiment 1, 4 CPsV-infected plants bearing BrCA colonies were introduced in separated cages with 12 ...

eIF2Bβ confers resistance to Turnip mosaic virus by recruiting ALKBH9B to modify viral RNA methylation

open access: yesPlant Biotechnology Journal, Volume 22, Issue 11, Page 3205-3217, November 2024.
Summary Eukaryotic translation initiation factors (eIFs) are the primary targets for overcoming RNA virus resistance in plants. In a previous study, we mapped a BjeIF2Bβ from Brassica juncea representing a new class of plant virus resistance genes associated with resistance to Turnip mosaic virus (TuMV).
