ABSTRACT Patterns of colonization Vitis vinifera L. cv. Chardonnay plantlets by a plant growth-promoting bacterium, Burkholderia sp. strain PsJN, were studied under gnotobiotic conditions. Wild-type PsJN and genetically engineered derivatives this tagged with gfp (PsJN:: 2x) or gusA 11) genes used to enumerate visualize tissue colonization. The rhizospheres 4- 5-week-old five developed leaves inoculated bacterial suspensions. Epiphytic endophytic patterns then monitored dilution plating...
This review presents an overview of eutypa dieback, esca and botryosphaeria the predominant grapevine trunk diseases worldwide. It covers their symptomatologies in trunk, leaves berries; characteristics different fungal species associated with them; host–pathogen interactions. Here, relationship is defined at cytological, physiological molecular levels. Currently available experimental tools for studying these diseases, both vitro field, are discussed. Finally, a progress report on control,...
Low temperatures damage many temperate crops, including grapevine, which, when exposed to chilling, can be affected by symptoms ranging from reduced yield up complete infertility. We have previously demonstrated that Burkholderia phytofirmans PsJN, a plant growth-promoting rhizobacteria (PGPR) colonizes is able reduce chilling-induced damage. hypothesized the induced tolerance may explained at least partly impact of bacteria on grapevine photosynthesis or carbohydrate metabolism during cold...
Several endophytic bacteria reportedly induce resistance to biotic stress and abiotic tolerance in several plant species. Burkholderia phytofirmans PsJN is a plant-growth-promoting rhizobacterium (PGPR) that able colonize grapevine tissues gray mold. Further, induces physiological changes increase low nonfreezing temperatures. To better understand how induced the observed phenomena, stress-related gene expression metabolite accumulation were monitored 6-week-old Chardonnay plantlets after...
ABSTRACT Rhamnolipids produced by the bacteria Pseudomonas aeruginosa are known as very efficient biosurfactant molecules. They used for a wide range of industrial applications, especially in food, cosmetics and pharmaceutical formulations well bioremediation pollutants. In this paper, role rhamnolipids novel molecules triggering defence responses protection against fungus Botrytis cinerea grapevine is presented. The effect was assessed using cell suspension cultures vitro‐plantlets. Ca 2+...
Summary The role of flagellin perception in the context plant beneficial bacteria still remains unclear. Here, we characterized sensing system flg22– FLAGELLIN SENSING 2 ( FLS 2) grapevine, and analyzed interaction with endophytic growth‐promoting rhizobacterium PGPR ) B urkholderia phytofirmans . functionality grapevine receptor, Vv 2, was demonstrated by complementation assays A rabidopsis thaliana fls2 mutant, which restored flg22‐induced H O production growth inhibition. Using synthetic...
Non-self-recognition of microorganisms partly relies on the perception microbe-associated molecular patterns (MAMPs) and leads to activation an innate immune response. Bacillus subtilis produces three main families cyclic lipopeptides (LPs), namely surfactins, iturins fengycins. Although LPs are involved in induced systemic resistance (ISR) activation, little is known about defence responses by these molecules their involvement local fungi. Here, we showed that purified surfactin,...
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...
