Transgenic plum Prunus domestica L., clone C5 (cv. HoneySweet) for protection against sharka disease

Journal of Integrative Agriculture, 2017
Sharka caused by Plum pox virus (PPV) is the most harmful disease of stone fruits in Europe and elsewhere in the world. There is no highly PPV resistant cultivar of plum.

Resistance to Sharka in Apricot: Comparison of Phase-Reconstructed Resistant and Susceptible Haplotypes of ‘Lito’ Chromosome 1 and Analysis of Candidate Genes [PDF]

Frontiers in Plant Science, 2019
Sharka, a common disease among most stone fruit crops, is caused by the Plum Pox Virus (PPV). Resistant genotypes have been found in apricot (Prunus armeniaca L.), one of which—the cultivar ‘Lito’ heterozygous for the resistance—has been used to map a ...

Tolerance of plant virus disease: Its genetic, physiological, and epidemiological significance

Food and Energy Security, Volume 12, Issue 6, November 2023., 2023
Plant viruses lead to biotic stress in plants, affecting growth, reproductive fitness and yield. Tolerance of viruses and virus disease may provide a host defence mechanism against deleterious effects, but further physiological and epidemiological studies are required to determine the circumstances in which it can be effectively used for crop ...

The Rysto immune receptor recognises a broadly conserved feature of potyviral coat proteins

New Phytologist, Volume 235, Issue 3, Page 1179-1195, August 2022., 2022
Summary Knowledge of the immune mechanisms responsible for viral recognition is critical for understanding durable disease resistance and successful crop protection. We determined how potato virus Y (PVY) coat protein (CP) is recognised by Rysto, a TNL immune receptor. We applied structural modelling, site‐directed mutagenesis, transient overexpression,

Dexterous Identification of Carcinoma through ColoRectalCADx with Dichotomous Fusion CNN and UNet Semantic Segmentation

Computational Intelligence and Neuroscience, Volume 2022, Issue 1, 2022., 2022
Human colorectal disorders in the digestive tract are recognized by reference colonoscopy. The current system recognizes cancer through a three‐stage system that utilizes two sets of colonoscopy data. However, identifying polyps by visualization has not been addressed.

Plum pox virus strains: Diversity and geographical distribution in Serbia [PDF]

Pesticidi i Fitomedicina, 2014
Plum pox virus (PPV) is the causal agent of Sharka disease. Since its discovery, Sharka has been considered as a calamity in plum orchards. PPV is present worldwide in many Prunus species, causing great economic losses.

ColoRectalCADx: Expeditious Recognition of Colorectal Cancer with Integrated Convolutional Neural Networks and Visual Explanations Using Mixed Dataset Evidence

Computational and Mathematical Methods in Medicine, Volume 2022, Issue 1, 2022., 2022
Colorectal cancer typically affects the gastrointestinal tract within the human body. Colonoscopy is one of the most accurate methods of detecting cancer. The current system facilitates the identification of cancer by computer‐assisted diagnosis (CADx) systems with a limited number of deep learning methods.

Effect of a traditional control method (tree removal) on the spread of sharka in an apricot orchard in Southeastern Spain

Phytopathologia Mediterranea, 2003
The spatial spread of sharka disease (Plum pox virus, PPV) was studied from 1990 to 2002 in a traditional apricot (Prunus armeniaca L.) orchard located in Murcia (Southeast of Spain).

THIRTEEN YEARS OF SHARKA DISEASE IN VALENCIA, SPAIN

Acta Horticulturae, 1998
Since the initial detection of PPV in Valencia (Spain), work on improvement of diagnosis methods and virus characterization have been developed, mainly with serological methods. Comparison of traps and sampling methods to evaluate aphid populations in the orchards, as well as identification of potential vectors have been made. Epidemiology and analysis

The phenotypically quantitative nature of hypersensitivity of European plum (Prunus domestica L.) against the Plum pox virus and its description using the hypersensitivity index

Horticultural Science, 2008
More than 1,300 seedlings of European plum originating from crossing combinations with at least one parent showing hypersensitivity resistance against PPV were analyzed for their reaction to artificial inoculation with PPV using the double grafting ...
