The pan-genome effector-triggered immunity landscape (Science)

Successful plant pathogens produce a suite of small molecules called effectors that are injected into plant cells and perturb plant defense. As a counter defense, plants have evolved intracellular receptors (called NLRs; nucleotide-binding domain leucine-rich repeat) that detect specific effectors and…

Three previously characterized resistances to yellow rust are encoded by a single locus Wtk1 (J. Exp. Bot.)

Yellow rust is a fungal disease of wheat. Three mutants with enhanced resistance were identified in wild emmer wheat from different locations were previously mapped to the same region of chromosome 1B. Given that each locus showed a different degree of resistance, it was presumed that they were non-allelic.…

The genetic architecture of colonization resistance in Brachypodium distachyon to non-adapted stripe rust (Puccinia striiformis) isolates (PLOS Gen.)

The host range of a pathogen depends on its ability to overcome various plant defense barriers and successfully complete its life cycle. Although host “jumps” are considered rare, the pathogens are able to infect plants other than their usual host with varying degree of success. Yellow stripe rust…

Nicotinamide Mononucleotide and Related Metabolites Induce Disease Resistance Against Fungal Phytopathogens in Arabidopsis and Barley (OA)

Sci. Rep. Plant defense activators are organic molecules that do not possess antimicrobial activity but have been shown to enhance plant disease resistance mechanisms. A comparison of some Fusarium-resistant and -susceptible barely cultivars suggested that NMN may act as a plant defense activator. RNAseq…
