Revealing structure and assembly cues for Arabidopsis root-inhabiting bacterial microbiota
TLDR
Methodology is described to characterize and compare soil- and root-inhabiting bacterial communities, which reveals not only a function for metabolically active plant cells but also for inert cell-wall features in the selection of soil bacteria for host colonization. Expand
Structure and functions of the bacterial microbiota of plants.
TLDR
The plant microbiota emerges as a fundamental trait that includes mutualism enabled through diverse biochemical mechanisms, as revealed by studies on plant growth- Promoting and plant health-promoting bacteria. 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.

Nuclear Activity of MLA Immune Receptors Links Isolate-Specific and Basal Disease-Resistance Responses
TLDR
In barley, intracellular mildew A (MLA) R proteins function in the nucleus to confer resistance against the powdery mildew fungus, revealing a mechanism by which these polymorphic immune receptors integrate distinct pathogen signals. Expand
Arabidopsis PEN3/PDR8, an ATP Binding Cassette Transporter, Contributes to Nonhost Resistance to Inappropriate Pathogens That Enter by Direct Penetration[W][OA]
Arabidopsis thaliana is a host to the powdery mildew Erysiphe cichoracearum and nonhost to Blumeria graminis f. sp hordei, the powdery mildew pathogenic on barley (Hordeum vulgare). Screening forExpand
Pre- and Postinvasion Defenses Both Contribute to Nonhost Resistance in Arabidopsis
TLDR
It is reported that Arabidopsis PEN2 restricts pathogen entry of two ascomycete powdery mildew fungi that in nature colonize grass and pea species. Expand
The RAR1 Interactor SGT1, an Essential Component of R Gene-Triggered Disease Resistance
TLDR
It is shown that RAR1 interacts with plant orthologs of the yeast protein SGT1, an essential regulator in the cell cycle, which indicates a link between disease resistance and ubiquitination. Expand
The Barley Mlo Gene: A Novel Control Element of Plant Pathogen Resistance
TLDR
Analysis of mutagen-induced recessive alleles of the barley Mlo locus revealed mutations leading in each case to alterations of the deduced Mlo wild-type amino acid sequence, compatible with a dual negative control function of the Mlo protein in leaf cell death and in the onset of pathogen defense. Expand
Conserved requirement for a plant host cell protein in powdery mildew pathogenesis
TLDR
A conserved requirement for MLO proteins in powdery mildew pathogenesis in the dicotyledonous plant species Arabidopsis thaliana is demonstrated, suggesting that within the Erysiphales (powdery mildews) the ability to cause disease has been a stable trait throughout phylogenesis. Expand
A Glucosinolate Metabolism Pathway in Living Plant Cells Mediates Broad-Spectrum Antifungal Defense
TLDR
It is proposed that reiterated enzymatic cycles, controlling the generation of toxic molecules and their detoxification, enable the recruitment of glucosinolates in defense responses. Expand
