Plant growth-promoting rhizobacteria (PGPR) are beneficial microorganisms that colonize the rhizosphere of many plant species and confer effects, such as an increase in growth. PGPR also well known inducers systemic resistance to pathogens plants. However, molecular mechanisms involved locally after direct perception these bacteria by cells still remain largely unknown. Burkholderia phytofirmans strain PsJN is endophytic colonizes grapevine protects against grey mould disease caused Botrytis...
Plant innate immunity is activated upon perception of invasion pattern molecules by plant cell-surface immune receptors. Several bacteria the genera Pseudomonas and Burkholderia produce rhamnolipids (RLs) from l-rhamnose (R)-3-hydroxyalkanoate precursors (HAAs). RL HAA secretion required to modulate bacterial surface motility, biofilm development, thus successful colonization hosts. Here, we show that lipidic secretome opportunistic pathogen aeruginosa, mainly comprising RLs HAAs, stimulates...
In grapevine Vitis vinifera L. cv Pinot noir, the Pathogenesis-Related (PR) proteins CHI4D and TL3 are among most abundant extractable PR of ripe berries accumulate during berry ripening from véraison until full maturation. Evidence was supplied in favor involvement these two protein families plant defense mechanisms development. order to better understand function grapevine, we analyzed their temporal spatial pattern expression maturation after an abiotic stress (UV-C) by situ hybridization...
In this work, the capacity of 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 induced expression basic beta-1,3-glucanase (Vvglu), chitinase (Vvchit1b) and PR10 (VvPR10.3) genes encoding three pathogenesis-related (PR) proteins involved grapevine against pathogens. Thus, all transcripts accumulated tissues reach maximum values after 24-72 h exposure, except...
Abstract Plant innate immunity is activated upon perception of invasion pattern molecules by plant cell-surface immune receptors. Several bacteria the genera Pseudomonas and Burkholderia produce rhamnolipids (RLs) from L- rhamnose ( R )-3-hydroxyalkanoate precursors (HAAs). RL HAA secretion required to modulate bacterial surface motility, biofilm development, thus successful colonization hosts. Here, we show that lipidic secretome opportunistic pathogen aeruginosa mostly comprising RLs HAAs...
