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 ...

First report of morphological and molecular characterization of Moroccan populations of Globodera pallida [PDF]

Journal of Nematology, 2021
Potato cyst nematodes (PCNs) are the most important potato pest causing major crop losses across the world with a quarantine status in many countries. In Morocco, several potato crops are infected with PCNs and the monitoring of potato production as well

Draft Transcriptome of Globodera ellingtonae [PDF]

Journal of Nematology, 2017
Abstract Globodera ellingtonae is a newly described cyst nematode found in Idaho, Oregon, and Argentina. Here we present the first transcriptome assembly of G. ellingtonae, providing a valuable resource for comparing the evolution of expressed genes between potato cyst nematode species.

Characterisation and mapping of a Globodera pallida resistance derived from the wild potato species Solanum spegazzinii. [PDF]

Theor Appl Genet
A new resistance locus acting against the potato cyst nematode Globodera pallida was mapped to chromosome VI in the diploid wild potato species Solanum spegazzinii CPC 7195.

Improvement of diagnostic markers for resistance to Globodera pallida and application for selection of resistant germplasms in potato breeding

Breeding Science, 2021
Occurrence of pale potato cyst nematode, Globodera pallida (Stone) Behrens, was first recorded in Japan in 2015. Among several control measures, cultivation of resistant potato (Solanum tuberosum L.) varieties is the most effective in cost and ...

Impact of Globodera ellingtonae on yield of potato (Solanum tuberosum)

Journal of Nematology, 2019
Globodera ellingtonae was described from Oregon and Idaho in 2012. Due to the close phylogenetic relationship of this nematode to the potato cyst nematodes G. pallida and G. rostochiensis, and evidence that G.

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.

Mapping the H2 resistance effective against Globodera pallida pathotype Pa1 in tetraploid potato [PDF]

Theoretical and Applied Genetics, 2019
The nematode resistance gene H2 was mapped to the distal end of chromosome 5 in tetraploid potato. The H2 resistance gene, introduced into cultivated potatoes from the wild diploid species Solanum multidissectum, confers a high level of resistance to the

The Draft Genome of Globodera ellingtonae [PDF]

Journal of Nematology, 2017
Abstract Globodera ellingtonae is a newly described potato cyst nematode (PCN) found in Idaho, Oregon, and Argentina. Here, we present a genome assembly for G. ellingtonae, a relative of the quarantine nematodes G. pallida and G. rostochiensis, produced using data from Illumina and Pacific Biosciences DNA sequencing technologies.

Influence of soil temperature on Globodera rostochiensis and Globodera pallida

Phytopathologia Mediterranea, 2014
Relationships between soil temperatures and the potato cyst nematode (PCN) life cycle and population multiplication were investigated to understand the risks to potato crops from PCN in relation to increasing soil temperatures associated with climate ...
