(Submitter supplied) Plants can perceive the presence of pathogens at the cell surface and plant damage-derived molecules via recognition of conserved microbial molecules, named pathogen- or microbe-associated molecular patterns (PAMPs) and damage associated molecular patterns (DAMPs). Well-studied examples of PAMPs are chito-oligomers, breakdown products of fungal cell walls and insect exoskeletons. Pectin-derived oligogalacturonides (OGs) are well-characterized DAMPs. more...

(Submitter supplied) The importance of oligogalacturonides for plant defence and growth has been described extensively in litterature. However, much of previous global transcriptome analyses for plants treated with oligogalacturonides have focused on long (>10 galacturonosyl residues) oligogalacturonides. This study focuses on the transcriptomic impact that trimeric oligogalacturonides and a mixture of oligogalacturonides have on plant transcriptomes and overall biology.

(Submitter supplied) The cell wall is a crucial structure in plant cells, and modifications in its composition often have a major impact on growth and development. However, the molecular mechanisms responsible for the negative effects of cell wall alterations on plant growth are largely unknown. It was previously shown that a reduction in the levels of de-esterified homogalacturonan, a major pectin component of cell walls, in Arabidopsis thaliana plants expressing a fungal polygalacturonase or mutated in the QUASIMODO2 gene (qua2-1 plants), cause severe growth defects. more...

(Submitter supplied) To identify direct targets of WRKY22, we created a transgenic Arabidopsis line that expresses a c-myc epitope-tagged WRKY22 and used ChIP followed by microarray hybridization (ChIP-chip) to screen for candidates and validate the in vivo protein-DNA interactions with ChIP followed by quantitative PCR (ChIP-Q-PCR). The WRKY22 and c-myc epitope tag fusion construct was generated and transformed into wrky22-ko2 plants. 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) Cytokinin signaling pathway, that is mediated by Arabidopsis Response Regulators (ARRs) proteins, has gained functional relevance in the modulation of plant disease resistance responses. We describe here a novel function of ARR6 in the regulation of Arabidopsis immunity and cell wall composition. arr6 mutants were found to be more susceptible and resistant, respectively, to the vascular bacteria Ralstonia solanacearum GMI1000 and the necrotrophic fungus Plectosphaerella cucumerina BMM. more...

(Submitter supplied) In addition to its essential metabolic functions biotin is suggested a critical role in regulating gene expression. The first committed enzyme in biotin biosynthesis in Arabidopsis, 7-keto-8-aminopelargonic acid synthase is encoded by At5g04620 (BIO4). We isolated a novel T-DNA insertion mutant of BIO4 (bio4-1) showing a spontaneous cell death phenotype that could be rescued both by exogenous biotin and genetic complementation. more...

(Submitter supplied) We determined on a genome-wide scale the flg22-induced in vivo DNA-binding dynamics of three of the most prominent WRKY factors, WRKY18, WRKY40 and WRKY33. The three WRKY factors each bound to more than 1000 gene loci predominantly at W-box elements, the known WRKY binding motif. Transcriptional analysis also revealed that WRKY18 and WRKY40 function redundantly as negative regulators of flg22-induced genes.

(Submitter supplied) A. thaliana lines with reduced lignin content through down-regulation of the lignin biosynthesis enzymes cinnamoyl CoA reductase (CCR) exhibit extensive cell wall remodeling which results in the release of a mixture of pectic oligosaccharide elicitors of pathogenesis-related (PR) protein gene expression through the salicylic acid signaling pathway. Loss of function of FERONIA, a CrRLK1-like subfamily receptor-like kinase resulted in loss of PR-1, -2 and- 5 gene activation in stems of the ccr1/fer-4 double mutant.

(Submitter supplied) Purpose: We recently identified a mutant (cork1) which did not respond to cellooligomers (COs). To find out the signaling events following CO perception, roots from the segregated wild-type and homozygous mutants (F2 generation from cork1-2 X AeqWT) were treated with 10 µM cellotriose and water. Total RNA from root tissue was extracted after 1 hour. The raw reads were mapped to TAIR10 reference genome with STAR (v. more...

(Submitter supplied) Background: Cell walls (CWs) are protein-rich polysaccharide matrices essential for plant growth and environmental acclimationadaptation. The CW constitutes the first physical barrier as well as a primary source of sugars for plant microbes, such as the  vascular pathogen Fusarium oxysporum (Fo). Fo colonizes roots, advancing through the plant primary CWs towards the vasculature, where it grows causing devastation in many crops. more...
