The potato cyst nematode Globodera pallida overcomes major potato resistance through selection on standing variation at a single locus. [PDF]

New Phytol
Summary Globodera pallida poses a major threat to potato production, with management strategies primarily relying on genetic resistance. However, increasing virulence in field populations across Western Europe raises major concerns for G. pallida control.

Adaptation of <i>Globodera pallida</i> to Individual Components Compromises the Durability of Pyramided Resistance in Potato. [PDF]

Evol Appl
ABSTRACT The use of resistant plants is an effective alternative to chemical products. But their sustainability is often compromised by the rapid adaptation of pathogen populations. For the cyst nematode Globodera pallida, a major parasite of potato, several quantitative trait loci (QTLs) conferring resistance have been identified, but their individual

Adaptation of the Cyst Nematode Globodera pallida to the Colinear Potato Resistant QTLs GpaV_vrn and GpaV_spl Involved Distinct Genomic Regions and Absence of Cross-Virulence. [PDF]

Mol Ecol
ABSTRACT The use of alternative methods to control cyst nematode populations has accelerated since the ban of chemical nematicides in Europe. The resistant QTL GpaVvrn, derived from the wild species Solanum vernei, is widely present in resistant European potato cultivars and provides strong protection against Globodera pallida populations although a ...

POTATO RESISTANCE TO GLOBODERA ROSTOCHIENSIS AND GLOBODERA PALLIDA USING MOLECULAR

Niva Povolzhya, 2023
Studies were carried out to identify potato genotypes with resistance genes against the potato cyst nematodes using molecular markers. The detection of disease resistance genes using DNA markers can be an alternative approach to select potentially resistant samples.

Occurrence and molecular characterization of cyst nematode species (Globodera spp.) associated with potato crops in Colombia.

PLoS ONE, 2021
Potato cyst nematodes (PCN) from the genus Globodera spp. cause major losses in the potato (Solanum tuberosum) industry worldwide. Despite their importance, at present little is known about the status of this plant pathogen in cultivated potatoes in ...

Morphological and molecular characterization of potato cyst nematode populations from The Nilgiris

The Indian Journal of Agricultural Sciences, 2020
Quarantine species of potato cyst nematodes (PCN), Globodera rostochiensis and G. pallida, were reported from Nilgiris during 1961. The studies were carried out at ICAR-CPRS, Muthorai, Ooty and ICAR-CPRI, Shimla during 2015–17.

PCR-RFLP diagnostic method for identifying Globodera species in Slovenia

Phytopathologia Mediterranea, 2011
Species identification within the genus Globodera is based on the morphological and morphometrical characters of the cysts and second stage juveniles, and these are included in the majority of identification keys.

The potato cyst nematode effector RHA1B is a ubiquitin ligase and uses two distinct mechanisms to suppress plant immune signaling. [PDF]

PLoS Pathogens, 2019
Plant pathogens, such as bacteria, fungi, oomycetes and nematodes, rely on wide range of virulent effectors delivered into host cells to suppress plant immunity.
