Plants lack the seemingly unlimited receptor diversity of a somatic adaptive immune system as found in vertebrates and rely on only relatively small set innate receptors to resist myriad pathogens. Here, we show that disease-resistant tomato plants use an efficient mechanism leverage limited nonself recognition capacity their system. We extracellular plant protein Cf-2 red currant ( Solanum pimpinellifolium ) has acquired dual resistance specificity by sensing perturbations common virulence...
The yellow potato cyst nematode, Globodera rostochiensis, is a devastating plant pathogen of global economic importance. This biotrophic parasite secretes effectors from pharyngeal glands, some which were acquired by horizontal gene transfer, to manipulate host processes and promote parasitism. G. rostochiensis classified into pathotypes with different resistance-breaking phenotypes. We generate high quality genome assembly for pathotype Ro1, identify putative transfer events, map expression...
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 effector proteins nematode secretions suppresses damage-triggered immune responses host. However, nature mode action most immunomodulatory compounds are not well understood. Here, we show venom allergen-like plant-parasitic selectively suppress immunity mediated by surface-localized...
Abstract The potato cyst nematode Globodera rostochiensis invades roots of host plants where it transforms cells near the vascular cylinder into a permanent feeding site. cell modifications are most likely induced by complex mixture proteins in stylet secretions nematodes. Resistance to nematodes conferred nucleotide-binding-leucine-rich repeat (NB-LRR) usually results programmed death and around site, is triggered recognition effectors secretions. However, actual role these activation...
The H1 locus confers resistance to the potato cyst nematode Globodera rostochiensis pathotypes 1 and 4. It is positioned at distal end of chromosome V diploid Solanum tuberosum genotype SH83-92-488 (SH) on an introgression segment derived from S. ssp. andigena. Markers a high-resolution genetic map (Bakker et al. in Theor Appl Genet 109:146–152, 2004) were used screen BAC library construct physical covering 341-kb region resistant haplotype coming SH. For comparison, maps also generated two...
The Grp1 locus confers broad-spectrum resistance to the potato cyst nematode species Globodera pallida and rostochiensis is located in GP21-GP179 interval on short arm of chromosome V potato. A high-resolution map has been developed using diploid mapping population RHAM026, comprising 1,536 genotypes. flanking markers GP21 GP179 have used screen genotypes for recombination events. Interval resistances G. Pa2 Ro5 resulted two nearly identical LOD graphs with highest score just north marker...
Plant-parasitic nematodes secrete effectors that manipulate plant cell morphology and physiology to achieve host invasion establish permanent feeding sites. Effectors from the highly expanded SPRYSEC (SPRY domain with a signal peptide for secretion) family in potato cyst have been implicated activation suppression of immunity, but mechanisms underlying these activities remain largely unexplored. To study used by effectors, we identified targets GpRbp-1 nematode Globodera pallida. Here, show...
To establish persistent infections in host plants, herbivorous invaders, such as root-knot nematodes, must rely on effectors for suppressing damage-induced jasmonate-dependent defenses. However, at present, the effector mechanisms targeting biosynthesis of biologically active jasmonates to avoid adverse responses are unknown. Using yeast two-hybrid, planta co-immunoprecipitation, and mutant analyses, we identified 12-oxophytodienoate reductase 2 (OPR2) an important target stylet-secreted...
Abstract Soil-borne cyst nematodes are obligatory sedentary parasites that cause severe losses to cultivation of major crops such as potato and soybean. Cyst establish specialised permanent feeding sites within the roots their host by manipulating plant morphology physiology through secreted effectors. Here we identified targets effector GpRbp-1 studied roles in plant-nematode interactions. was found interact yeast planta with Arabidopsis homologues Siz/PIAS-type E3 SUMO ligase SIZ1. Our...
