Revisiting steroidal glycoalkaloids as hatching stimulants for Globodera rostochiensis and Globodera pallida

Pest Management Science
AbstractBACKGROUNDPotato production faces significant challenges from pests, particularly potato cyst nematodes (PCNs) such as Globodera rostochiensis and Globodera pallida. These nematodes are classified as regulated quarantine pests due to their detrimental effect on potato yields, yet populations continue to persist in the soil despite stringent ...

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 ...

Life cycle and morphological identification of Globodera spp. related to potato (Solanum tuberosum L.) phenology in Nariño, Colombia

Revista de Ciencias Agrícolas, 2021
Nematodes of Globodera genus are considered one of the most important and limiting pests for potato crops, since these pathogens are difficult to control and cause losses between 20 and 50% of production.

Inhibitors of Sodium-Dependent Serotonin Transporter Protein (SERT) as Potential New Nematicides. [PDF]

Chem Biodivers
ABSTRACT Nematodes of the genus Meloidogyne cause major losses in agricultural production worldwide. To identify potentially useful chemical structures for developing new nematicides, this study initially aimed to determine in silico – using computationally efficient techniques – the protein target of chaetoglobosins A and B in these nematodes.

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.

Quarantine nematode species and pathotypes potentially dangerous for domestic potato production: populations diversity and the genetics of potato resistance

Вавиловский журнал генетики и селекции, 2020
The review considers quarantine species and nematode pathotypes potentially dangerous for domestic potato production. Potatoes are affected by more than 30 types of parasitic nematodes, but the review focuses on the most harmful representatives of genera

Empirical Evidence of a Bet-Hedging Strategy in the Carrot Cyst Nematode <i>Heterodera carotae</i>. [PDF]

Ecol Evol
Phytoparasitic cyst nematodes with narrow host range are expected to develop a diversified temporal bet‐hedging strategy as they cannot predict the presence and quality of host plants. The present work confirmed this hypothesis for the first time in a plant‐parasitic nematode, Heterodera carotae.
