Nonhost resistance describes the immunity of an entire plant species against nonadapted pathogen species. We report that Arabidopsis PEN2 restricts pathogen entry of two ascomycete powdery mildew fungi that in nature colonize grass and pea species. The PEN2 glycosyl hydrolase localizes to peroxisomes and acts as a component of an inducible preinvasion resistance mechanism. Postinvasion fungal growth is blocked by a separate resistance layer requiring the EDS1-PAD4-SAG101 signaling complex… Expand

Arabidopsis non-host resistance to powdery mildews.
TLDR
The genetic dissection of Arabidopsis non-host resistance to non-adapted biotrophic powdery mildew fungi provided evidence for functionally redundant but operationally distinct pre- and post-invasion immune responses. Expand
Live and let die--Arabidopsis nonhost resistance to powdery mildews.
TLDR
It is now generally accepted that NHR of Arabidopsis to powdery mildews comprises two distinct layers of defence: pre-invasion entry control at the cell periphery and post-Invasion resistance based on cell death execution. Expand
Host versus nonhost resistance: distinct wars with similar arsenals.
TLDR
The mechanisms of host and nonhost resistance against fungal and bacterial plant pathogens are described and compared to identify similarities and differences, and their practical applications in crop improvement are compared. Expand
Nonhost resistance of Arabidopsis thaliana against Colletotrichum species
TLDR
Both the tryptophan-derived metabolic pathway and glutathione synthesis play critical roles in the postin invasive resistance against C. tropicale, although the molecular mechanism of postinvasive resistance remains to be elucidated. Expand
Glutathione and tryptophan metabolites are key players in Arabidopsis nonhost resistance against Colletotrichum gloeosporioides
TLDR
It is shown that the biosynthesis of Trp-derived phytochemicals is also essential for resistance to Cg during the post-invasive HR, and GSH1 and these metabolites are dispensable for the induction of HR cell death, which is triggered in the non-invading mesophyll cells adjacent to the Cg-invaded epidermal cells. Expand
Nonhost resistance of plants to powdery mildew—New opportunities to unravel the mystery
TLDR
In many of these studies, host and nonhost interactions with appropriate and inappropriate powdery mildew fungi, respectively, have been used and fulfil an important role as model systems for the study of nonhost resistance to fungal pathogens. Expand
Plant nonhost resistance: paradigms and new environments.
TLDR
New evidence supports the NHR paradigm that posits the inability of potential pathogens to colonise nonhost plants is frequently due to molecular incompatibility between pathogen virulence factors and plant cellular targets. Expand
ERECTA contributes to non-host resistance to Magnaporthe oryzae in Arabidopsis
TLDR
Results suggest that ERECTA is involved in both penetration and post-penetration resistance to M. oryzae in Arabidopsis. Expand
Arabidopsis CURLY LEAF functions in leaf immunity against fungal pathogens by concomitantly repressing SEPALLATA3 and activating ORA59.
TLDR
Results strongly suggest that concomitant SEP3 repression and ORA59 induction via CLF are required for Arabidopsis leaf immunity to Colletotrichum fungi, uncoupled from CLF's function in growth and leaf development. Expand
Arabidopsis Phospholipase Dδ Is Involved in Basal Defense and Nonhost Resistance to Powdery Mildew Fungi1[W]
TLDR
It is proposed that PLD is involved in defense signaling in nonhost resistance against powdery mildew fungi and put PLDδ forward as the main isoform participating in this process. Expand

SNARE-protein-mediated disease resistance at the plant cell wall
TLDR
It is shown that resistance in barley requires a SNAP-25 (synaptosome-associated protein, molecular mass 25 kDa) homologue capable of forming a binary SNAP receptor (SNARE) complex with ROR2, and functions associated with SNARE-dependent penetration resistance are dispensable for immunity mediated by race-specific resistance (R) genes, highlighting fundamental differences between these two resistance forms.

Loss of actin cytoskeletal function and EDS1 activity, in combination, severely compromises non-host resistance in Arabidopsis against wheat powdery mildew.
TLDR
Actin cytoskeletal function and EDS1 activity, in combination, are major contributors to NHR in Arabidopsis against wheat powdery mildew. Expand
Recruitment and interaction dynamics of plant penetration resistance components in a plasma membrane microdomain.
TLDR
Noninvasive fluorescence-based imaging is used to show that fluorescently tagged MLO protein becomes redistributed in the plasma membrane (PM) and accumulates beneath fungal appressoria coincident with the initiation of pathogen entry into host cells. Expand
Host and non-host pathogens elicit different jasmonate/ethylene responses in Arabidopsis.
TLDR
The data suggest that biotrophic host pathogens must either suppress or fail to elicit the JA/ET signal transduction pathway to be able to infect and inhibit Arabidopsis. Expand
Bacterial disease resistance in Arabidopsis through flagellin perception
TLDR
It is shown that treatment of plants with flg22, a peptide representing the elicitor-active epitope of flagellin, induces the expression of numerous defence-related genes and triggers resistance to pathogenic bacteria in wild-type plants, but not in plants carrying mutations in the flageLLin receptor gene FLS2. Expand
Arabidopsis SENESCENCE-ASSOCIATED GENE101 Stabilizes and Signals within an ENHANCED DISEASE SUSCEPTIBILITY1 Complex in Plant Innate Immunityw⃞
TLDR
It is demonstrated by a combination of cell fractionation, coimmunoprecipitation, and fluorescence resonance energy transfer experiments the existence of an EDS1–SAG101 complex inside the nucleus that is molecularly and spatially distinct from EDS2–PAD4 associations in the nucleus and cytoplasm, suggesting that dynamic interactions of EDS 1 and its signaling partners in multiple cell compartments are important for plant defense signal relay. Expand
The PEN1 syntaxin defines a novel cellular compartment upon fungal attack and is required for the timely assembly of papillae.
TLDR
The role of PEN1 and of its closest homologue, SYP122, identified as a syntaxin whose expression is responsive to infection are examined, which concludes thatSYP122 may have a general function in secretion, including a role in cell wall deposition. Expand
H2O2 plays different roles in determining penetration failure in three diverse plant-fungal interactions.
TLDR
It is demonstrated that breakdown products of the cell wall released by the localized application of hemicellulase elicit localized responses including, sequentially, extracellular H2O2 generation; accumulation of phenolic compounds; and cross-linking of proteins in thecell wall. Expand
Corruption of host seven-transmembrane proteins by pathogenic microbes: a common theme in animals and plants?
TLDR
Potential analogies between human chemokine receptors and the plant seven-transmembrane MLO protein, a candidate serving a dual role as docking molecule and defence modulator for the phytopathogenic powdery mildew fungus are reviewed. Expand

The completion of the Arabidopsis thalianagenome sequencing project has enabled us, for the first time, to determine the total number of GH Family 1 members in a higher plant and to investigate the substrate specificity of each mature hydrolase after its heterologous expression in the Pichia pastoris expression system.
