(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) 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.

Analysis of 14-day-old Columbia-0 seedlings treated with hydrolyzed crab-shell chitin or chito-octamer. Chitin is a major component of fungal walls and insect exoskeletons. Results provide insight into the signaling pathways involved in activating defense genes in response to chito-oligomers.

(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) Chitin, a polymer of N-acetyl-glucosamne, is a component of the cell walls of many plant fungal pathogens. During the infection process, the released chitin fragments (such as chitooctaose) from fungal cell walls by plant enzymes can trigger plant defense response and gene activation. The current work studies the regulation of Arabidopsis genes by the purified chitin fragment chitooctaose. We used the Affymetric Arabidopsis whole gene arrays to study the gene expression caused by chitin (chitooctaose). more...

(Submitter supplied) The goal of the microarray experiment was to identify defense genes that were differentially expressed in the Arabidopsis mutants med16, med8, elp2, wild type in response to infection of the necrotrophic fungal pathogen Sclerotinia sclerotiorum. Results indicated that, compared with the wild type, the jasmonic acid (JA) biosynthesis genes LOX3, AOC3, and OPR3, ethylene (ET) biosynthesis genes ACS2 and ACS8, as well as salicylic acid (SA) biosynthesis genes ICS1 and EDS5 were up-regulated in med16 in local tissues at 1 day post-inoculation (dpi) and/or systemic tissues at 4 dpi. 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) Sugar is propose to be a signal molecules for defense in plants. Here, using RNA-seq, we revealed that the application of non-metabolizable glucose analogue 2-deoxy-d-glucose induces the expression of defense-related genes in Arabidopsis. In addition, loss of sugar transporters (STPs) leads to altered responsiveness to flg22, suggesting that sugar-mediated signaling contributes to plant defense.
