TL;DR: 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.

TL;DR: It is reported that Arabidopsis PEN2 restricts pathogen entry of two ascomycete powdery mildew fungi that in nature colonize grass and pea species.

TL;DR: The authors showed that pen3 mutants were compromised in resistance to the necrotroph Plectosphaerella cucumerina and to two additional inappropriate biotrophs, pea powdery mildew (Erysiphe pisi) and potato late blight (Phytophthora infestans).

TL;DR: Depletion of callose from papillae in gsl5 plants marginally enhanced the penetration of the grass powdery mildew fungus Blumeria graminis on the nonhost Arabidopsis, providing strong genetic evidence that the GSL genes of higher plants encode proteins that are essential for callose formation.

TL;DR: It is shown that PGN sensing and immunity to bacterial infection in Arabidopsis thaliana requires three lysin-motif (LysM) domain proteins, and proposed that lineage-specific PGN perception systems have arisen through convergent evolution.
