First Insight Into Multiple Paternity in the Potato Cyst Nematode Globodera pallida Facing Masculinizing Plant Resistance [PDF]

Ecology and Evolution
Polyandry is a common reproductive behaviour in nature, and it was observed in several plant parasitic cyst nematodes. For the potato cyst nematode Globodera pallida, polyandry is assumed but has never been demonstrated and quantified.

A Novel Rhabdovirus Associated with the Idaho Population of Potato Cyst Nematode Globodera pallida [PDF]

Viruses, 2022
Globodera pallida, a potato cyst nematode (PCN), is a quarantine endoparasitic pest of potato (Solanum tuberosum) in the US due to its effects on yield and quality of potato tubers.

Solanoeclepin B, a hatching factor for potato cyst nematode. [PDF]

Sci Adv, 2023
The potato cyst nematode (PCN) causes extensive crop losses worldwide. Because the hatching of PCN requires host-derived molecules known as hatching factors (HFs), regulating HF production in host plants may help to control this harmful pest. Solanoeclepin A (SEA), isolated from potato, is the most active HF for PCN; however, its biosynthesis is ...

Characterization and response of two potato receptor-like kinases to cyst nematode infection

Plant Signaling and Behavior, 2022
Plant-parasitic cyst nematodes (Heterodera and Globodera spp.) secrete CLAVATA3/EMBRYO SURROUNDING REGION-RELATED (CLE) effector proteins, which act as ligand mimics of plant CLE peptides to promote successful nematode infection.

Abamectin Efficacy on the Potato Cyst Nematode Globodera pallida. [PDF]

Plants (Basel), 2019
The potato cyst nematode Globodera pallida is a major pest of the potato crop. Abamectin is a biological pesticide showing high nematicide activity, but its efficacy to control G. pallida has not been investigated to date. In this study, combination of different abamectin concentrations ranging from 1.125 to 36 µg/mL x exposure times from 24 to 384 h ...

Techniques for characterization and eradication of potato cyst nematode: a review. [PDF]

J Parasit Dis, 2017
Correct identification of species and pathotypes is must for eradication of potato cyst nematodes (PCN). The identification of PCN species after completing the life cycle is very difficult because it is based on morphological and morphometrical characteristics.

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.

A chromosome-level genome assembly of Solanum brevicaule (PI 473011) Y1-5, a wild potato relative with robust resistance to potato cyst nematodes. [PDF]

Plant Genome
Abstract Potato cyst nematodes (PCNs), Globodera rostochiensis and Globodera pallida, are globally recognized quarantine pests that can cause severe yield losses in potatoes (Solanum tuberosum L.) if left uncontrolled. Deploying host resistance remains the most effective, economical, and environmentally sustainable strategy for PCN control.

Mycorrhizal symbiosis drives tolerance to potato cyst nematodes. [PDF]

iScience
Host plant tolerance to pathogens is increasingly relevant as resistance sources and control options become scarce. Arbuscular mycorrhizal (AM) fungi are known to enhance plant stress tolerance, but it remains unclear whether they are essential for, or complement, innate tolerance. We observed that potato cultivars described as tolerant to G.

Resisting Potato Cyst Nematodes With Resistance [PDF]

Frontiers in Plant Science, 2021
Potato cyst nematodes (PCN) are economically important pests with a worldwide distribution in all temperate regions where potatoes are grown. Because above ground symptoms are non-specific, and detection of cysts in the soil is determined by the intensity of sampling, infestations are frequently spread before they are recognised.
