(Submitter supplied) Perception of microbe-associated molecular patterns by host cell-surface pattern recognition receptors triggers a series of immune responses such as activation of mitogen-activated protein kinase (MAPK) cascades. In Arabidopsis thaliana, the receptor-like cytoplasmic kinase PBL27 interacts with the chitin receptor CERK1 and regulates chitin-induced MAPK activation. We found that the MAPK kinase kinase MAPKKK5 connects PBL27 to the downstream MAPK Kinases (MKK4/5) and MAPKs (MPK3/6). more...

(Submitter supplied) Recognition of microbial patterns by host pattern recognition receptors is a key step in immune activation in multicellular eukaryotes. Peptidoglycans (PGN) are major components of bacterial cell walls and possess immunity-stimulating activities in metazoans and plants. Here, we show that PGN sensing in Arabidopsis thaliana requires three LysM domain proteins, LYM1, LYM3 and CERK1.

(Submitter supplied) Mature grapevine berries at the harvesting stage (MB) are very susceptible to the gray mold fungus Botrytis cinerea while veraison berries (VB) are not. We conducted simultaneous microscopic and transcriptomic analyses of the pathogen and the host to investigate the infectious process developed by B. cinerea on MB versus VB, and the plant defense mechanisms deployed to stop the fungus development. On the pathogen side, our genome-wide transcriptomic data revealed that B. more...

(Submitter supplied) To see the function of CEBiP in the chitin elicitor signaling in rice cells, a plasmid for the gene-specific knock-down by RNA interference (RNAi) was constructed by using a sequence for the 3’-terminal region of CEBiP and transformed into the rice cells by using Rhizobium radiobacter (Agrobacterium tumefaciens). chitinoligomer was added (or not added) to the medium. For the control of them, rice cells that non transformed wild type was used. more...

(Submitter supplied) We treated Arabidopsis seedlings with chitosan and carried out a transcript profiling analysis (GeneChip microarrays) in order to identify genes and transcription factors regulated by chitosan. The results showed that jasmonate and defense responsive genes, camalexin and lignin biosynthetic genes were among genes up-regulated by chitosan. Several transcription factors are also strongly induced by chitosan. more...

(Submitter supplied) Alternaria brassicicola is a successful saprophyte and necrotrophic plant pathogen. Molecular determinants of its life style shift between saprophyte and pathogen, however, are unknown. To identify these determinants we studied nonpathogenic mutants of a transcription factor-coding gene, AbPf2. Frequency and timing of germination and appressorium formation on host plants were similar between the nonpathogenic Δabpf2 mutants and wild-type A. more...

(Submitter supplied) Salicylic acid (SA)-induced defense responses are important factors during effector triggered immunity and microbe-associated molecular pattern (MAMP)-induced immunity in plants. This article presents evidence that a member of the Arabidopsis CBP60 gene family, CBP60g, contributes to MAMP-triggered SA accumulation. CBP60g is inducible by both pathogen and MAMP treatments. Pseudomonas syringae growth is enhanced in cbp60g mutants. more...

(Submitter supplied) Expression profiling of wild-type plants and mutants with defects in key components of the defense signaling network was used to model the Arabidopsis network 24 hours after infection by Pseudomonas syringae pv. maculicola strain Psm ES4326. Results using the Affymetrix ATH1 array revealed that expression levels of most pathogen-responsive genes were affected by mutations in coi1, ein2, npr1, pad4, or sid2. more...

(Submitter supplied) Since chitooligosaccharides are water-soluble, biodegradable and nontoxic compounds, their application may be considered as a promising plant-protecting agent. However, the molecular and cellular modes of action of COs are not yet understood. Transcriptional changes in pea roots treated with COs were investigated via RNA sequencing. Pea roots treated with the deacetylated CO8-DA at low concentration (10-5 М) were harvested 24 h after treatment and their expression profiles were compared against medium-treated control plants. more...
