Abstract

Plant innate immunity is activated upon perception of invasion pattern molecules by plant cell-surface immune receptors. Several bacteria of the genera Pseudomonas and Burkholderia produce rhamnolipids (RLs) from L-rhamnose and ( R )-3-hydroxyalkanoate precursors (HAAs). RL and HAA secretion is required to modulate bacterial swarming motility behavior. The bulb-type lectin receptor kinase LIPOOLIGOSACCHARIDE-SPECIFIC REDUCED ELICITATION/S-DOMAIN-1-29 (LORE/SD1-29) mediates medium-chain 3-hydroxy fatty acid (mc-3-OH-FA) sensing in the plant Arabidopsis thaliana . Here, we show that the lipidic secretome from Pseudomonas aeruginosa comprising RLs, HAAs and mc-3-OH-FAs stimulates Arabidopsis immunity. HAAs, like mc-3-O-FAs, are sensed by LORE and induce canonical immune signaling and local resistance to plant pathogenic Pseudomonas infection. By contrast, RLs trigger an atypical immune response and resistance to Pseudomonas infection independent of LORE. Thus, the glycosyl moieties of RLs, albeit abolishing sensing by LORE, do not impair their ability to trigger plant defense. In addition, our results show that RL-triggered immune response is affected by the sphingolipid composition of the plasma membrane. In conclusion, RLs and their precursors released by bacteria can both be perceived by plants but through distinct mechanisms.

Abstract

International audience; In their environment, plants are frequently challenged by pathogenic microorganisms. To deal with these pathogens, plants possess an arsenal of defence mechanisms, quickly activated following microorganism perception. This perception involves Microbe-Associated Molecular Patterns (MAMPs) that are recognized by plant cells through Pattern Recognition Receptors (PRRs) resulting in plant innate immunity (MTI, MAMP-Triggered Immunity). We previously showed in the laboratory that a natural rhamnolipids secretome (RLsec), produced by Pseudomonas aeruginosa, induce classical markers of plant immunity on Arabidopsis thaliana leaves and is highly effective on several plants to induce local resistance at the foliar level against phytopathogenic microorganisms 1, 2, 3. Among the RLsec constituents, the 3-hydroxydecanoic acid (3-OH-C10:0) synthesis precursor of rhamnolipids (RLs) was identified. The aim of this study is to determine if the 3-OH-C10:0 precursor of RLs is perceived by A. thaliana roots and if this perception triggers a systemic resistance against the necrotrophic fungus Botrytis cinerea.

Abstract

In this work, the capacity of the soil-applied herbicide flumioxazin (fmx) to trigger defence mechanisms was assessed using 6-week-old in vitro grown Vitis vinifera L. plantlets. Time-course studies demonstrated that the herbicide induced the expression of basic β-1,3-glucanase (Vvglu), basic chitinase (Vvchit1b) and PR10 (VvPR10.3) genes encoding three pathogenesis-related (PR) proteins involved in grapevine defence against pathogens. Thus, all transcripts accumulated in grapevine tissues to reach maximum values after 24–72 h of herbicide exposure, except for VvPR10.3 gene expression, which was induced in roots and stems but not in leaves. Induction of PR genes was observed to a greater extent in roots and leaves, and its intensity diminished in the stems although still remained noteworthy. The activities of β-1,3-glucanase and chitinase enzymes significantly increased in the whole plant after herbicide exposure and were still stimulated 21 days after the beginning of treatments. Similarly, the most remarkable effect occurred in roots. However, all enzyme activities tested were stimulated in the upper aerial tissues as well, indicating that fmx or a derived product acts systemically, likely via root uptake. [ABSTRACT FROM AUTHOR]
