Mannan oligosaccharides trigger multiple defence responses in rice and tobacco as a novel danger‐associated molecular pattern - Zang - 2019 - Molecular Plant Pathology. Introduction Unlike vertebrate animals, plants rely entirely on an innate immune system for their resistance against various pathogens.
Plant innate immune response has two layers: pattern‐triggered immunity (PTI) and effector‐triggered immunity (ETI) (Chisholm et al., 2006; Jones and Dangl, 2006). The first layer immune response is initiated by recognition of microbe or modified plant‐derived molecules such as flagellin, lipopolysaccharides, chitin, and oligogalacturonides (OGAs) through pattern‐recognition receptors (PRRs) located on the cell membrane (Hayafune et al., 2014; Zipfel et al., 2004). Oligosaccharides are low molecular weight saccharide polymers with degrees of polymerization (DP) between 2 and 10, mainly derived from plant cellulose or hemicellulose like pectins, xyloglucans, cellodextrins etc. In our previous study, we identified a novel thermostable mannanase BpMan5, which was encoded by Bacillus pumilus GBSW19 (Zang et al., 2015).

It must be completely suppressed under non‐disease conditions since improper activation will lead to a spontaneous cell death phenotype which can be very detrimental to plant growth (e.g. Genome-wide functional analyses of plant coiled–coil NLR-type pathogen receptors reveal essential roles of their N-terminal domain in oligomerization, networking, and immunity.

An EDS1-SAG101 Complex is Essential for TNL-mediated Immunity in Nicotiana benthamiana. Plant–necrotroph co-transcriptome networks illuminate a metabolic battlefield. A central goal of studying host-pathogen interaction is to understand how host and pathogen manipulate each other to promote their own fitness in a pathosystem.
Co-transcriptomic approaches can simultaneously analyze dual transcriptomes during infection and provide a systematic map of the cross-kingdom communication between two species. Here we used the Arabidopsis-B. cinerea pathosystem to test how plant host and fungal pathogen interact at the transcriptomic level. We assessed the impact of genetic diversity in pathogen and host by utilization of a collection of 96 isolates infection on Arabidopsis wild-type and two mutants with jasmonate or salicylic acid compromised immunities.
We identified ten B. cinerea gene co-expression networks (GCNs) that encode known or novel virulence mechanisms. Identification of a gene cluster for the synthesis of the plant hormone abscisic acid in the plant pathogen Leptosphaeria maculans. JavaScript is disabled on your browser.

Subsets of NLR genes show differential signatures of adaptation during colonisation of new habitats - Stam - Nucleotide binding site, Leucine‐rich repeat Receptors (NLRs), are canonical resistance (R) genes in plants, fungi and animals, functioning as central (helper) and peripheral (sensor) genes in a signalling network.
We investigate NLR evolution during the colonisation of novel habitats in a model tomato species, Solanum chilense. We used R‐gene enrichment sequencing (RENSeq) to obtain polymorphism data at NLRs of 140 plants sampled across 14 populations covering the whole species range. We inferred the past demographic history of habitat colonisation by resequencing whole genomes from three S. chilense plants from three key populations, and performing Approximate Bayesian Computation using data from the 14 populations. Using these parameters we simulated the genetic differentiation statistics distribution expected under neutral NLR evolution, and identified small subsets of outlier NLRs exhibiting signatures of selection across populations.
