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...
The surface of plant leaves, or the phyllosphere, harbors hyperdiverse microbial communities. These communities mediate foliar functional traits, influence fitness, and contribute to several ecosystem functions, including nutrient water cycling. In this review, we briefly recall history phyllosphere research present features habitat. Adopting a recent framework for evolutionary community ecology, then review evidence each four major processes shaping communities: dispersal, diversification,...
The microbial component of healthy seeds - the seed microbiome appears to be inherited between plant generations and can dynamically influence germination, performance, survival. As such, methods optimize microbiomes major crops could have far-reaching implications for breeding crop improvement enhance agricultural food, feed, fiber production. Here, we describe a new approach modulate elite embryos concomitantly design traits mediated by microbiomes. Specifically, discovered that...
The colonization pattern of Vitis vinifera L. by Burkholderia phytofirmans strain PsJN was determined using grapevine fruiting cuttings with emphasis on putative inflorescence under nonsterile conditions. Two-week-old rooted plants harbouring flower bud initials, grown in soil, were inoculated PsJN∷gfp2x. Plant subsequently monitored at various times after inoculation plate counts and epifluorescence and/or confocal microscopy. Strain chronologically detected the root surfaces, endorhiza,...
Summary Weeds and crop plants select their microbiota from the same pool of soil microorganisms, however, ecology weed microbiomes is poorly understood. We analysed associated with roots rhizospheres grapevine four species ( Lamium amplexicaule L., Veronica arvensis Lepidium draba L. Stellaria media L.) growing in proximity vineyard using 16S rRNA gene sequencing. also isolated characterized 500 rhizobacteria root endophytes grapevine. Microbiome data analysis revealed that all hosted...
Cyclic lipopeptides (cLP) and especially surfactins produced by Bacillus spp. trigger biofilm formation root colonization are crucial for biocontrol activity systemic resistance in plants. atrophaeus 176s isolated from the moss Tortella tortuosa produces cLP fengycins, iturins surfactins, possesses antifungal activities can protect tomato, lettuce sugar beet against Rhizoctonia solani infection. In B. we identified first time variant surfactin C, which differs A subtilis amyloliquefaciens an...
Serendipita (Piriformospora) indica is a fungal endophytic symbiont with the capabilities to enhance plant growth and confer resistance different stresses. However, application of this fungus in field has led inconsistent results, perhaps due antagonism other microbes. Here, we studied impact individual bacterial isolates from community on vitro S. indica. We further analyzed how combinations bacteria influence protection against phytopathogens Fusarium oxysporum Rhizoctonia solani....
Abstract Soil microbiota has increasingly been shown to play an integral role in viticulture resilience. The emergence of new metagenomic and culturomic technologies led significant advances the study microbial biodiversity. In agricultural sector, soil plant microbiomes have found significantly improve resistance environmental stressors diseases, as well influencing crop yields fruit quality thus improving sustainability under shifting environments. Grapevines are usually cultivated a scion...
Production from crops of pome, stone fruit, nut, berry citrus, grapevine, and olive is increasingly threatened by fungal trunk diseases (FTD). These the consequent production losses are major problems. Many fungi (including Botryosphaeriaceae, Calosphaeriaceae, Diaporthaceae, Diatrypaceae, Nectriaceae, Phaeomoniellaceae, Pleosporaceae, Togniniaceae, Valsaceae) infect host wood, mainly through wounds subsequent colonization woody tissues, causing symptoms such as cankers, gummosis, wood...
In this study, the biocontrol ability and colonization behavior of a highly antagonistic Streptomyces mutabilis strain, named IA1, recently isolated from Saharan soil, were assessed on wheat seedlings. study we showed that strain IA1 secretes IAA GA3 is able to enhance growth Using DOPE-FISH coupled with confocal laser scanning microscopy (CLSM), observed moreover following caryopsis inoculation plant can colonize rhizoplane, surface as well endorhiza, crossing rhizodermis up vascular...
