Two evolutionary distinct effectors from a nematode and virus target RanGAP1 and 2 via the WPP domain to promote disease

Octavina C. A. Sukarta, Amalia Diaz‐Granados, Erik J. Slootweg, Hein A. Overmars et autres

ABSTRACT The Gpa2 and Rx1 intracellular immune receptors are canonical CC-NB-LRR proteins belonging to the same R gene cluster in potato. Despite sharing high sequence homology, they have evolved to provide defence against unrelated pathogens. Gpa2 detects Gp-RBP-1 effectors secreted by the …

The effector GpRbp‐1 of Globodera pallida targets a nuclear HECT E3 ubiquitin ligase to modulate gene expression in the host

Amalia Diaz‐Granados, Mark G. Sterken, Hein A. Overmars, Roel Ariaans et autres

Plant-parasitic nematodes secrete effectors that manipulate plant cell morphology and physiology to achieve host invasion and establish permanent feeding sites. Effectors from the highly expanded SPRYSEC (SPRY domain with a signal peptide for secretion) family in potato cyst nematodes have been implicated …

SIZ1 is a nuclear host target of the nematode effector GpRbp1 from Globodera pallida that acts as a negative regulator of basal plant defense to cyst nematodes

Amalia Diaz‐Granados, Mark G. Sterken, Jarno Persoon, Hein A. Overmars et autres

Abstract Soil-borne cyst nematodes are obligatory sedentary parasites that cause severe losses to cultivation of major crops such as potato and soybean. Cyst nematodes establish specialised permanent feeding sites within the roots of their host by manipulating plant morphology and physiology through …

The Globodera pallida SPRYSEC Effector GpSPRY-414-2 That Suppresses Plant Defenses Targets a Regulatory Component of the Dynamic Microtubule Network

Yuanyuan Mei, Kathryn Mary Wright, Annelies Haegeman, Lander Bauters et autres

The white potato cyst nematode, Globodera pallida, is an obligate biotrophic pathogen of a limited number of Solanaceous plants. Like other plant pathogens, G. pallida deploys effectors into its host that manipulate the plant to the benefit of the nematode. Genome analysis …

SPRYSEC Effectors: A Versatile Protein-Binding Platform to Disrupt Plant Innate Immunity

Amalia Diaz‐Granados, Andrei‐José Petrescu, Aska Goverse, Geert Smant

Persistent infections by sedentary plant-parasitic nematodes are a major threat to important food crops all over the world. These round worms manipulate host plant cell morphology and physiology to establish sophisticated feeding structures. Key modifications to plant cells during their transition into …

GpRpb-1 from Globodera pallida manipulates plant post-translational modification in host cells to promote nematode infection

SPRYSECs: activators and suppressors of effector-triggered immunity in plants

W.J. Postma, Hein A. Overmars, Amalia Diaz‐Granados, Erik J. Slootweg et autres

The potato cyst nematodes Globodera rostochiensis and G. pallida invade roots of Solaneceous host plants where they transform cells near the vascular cylinder into a permanent feeding site. The host cell modifications are most likely brought about by a complex mixture of …

Apoplastic Venom Allergen-like Proteins of Cyst Nematodes Modulate the Activation of Basal Plant Innate Immunity by Cell Surface Receptors

Jose L. Lozano‐Torres, Ruud H. P. Wilbers, Sonja Warmerdam, Anna Finkers‐Tomczak et autres

Despite causing considerable damage to host tissue during the onset of parasitism, nematodes establish remarkably persistent infections in both animals and plants. It is thought that an elaborate repertoire of effector proteins in nematode secretions suppresses damage-triggered immune responses of the host. …
