Apple replant disease (ARD) occurs when apple is repeatedly planted at the same site, leading to growth reductions and losses in fruit yield quality. Up now, etiology has been poorly understood; however, soil (micro)biota are known be involved. Because endophytes often colonize plants via rhizosphere, this study aimed comparing bacterial endophytic root microbiome growing ARD-affected unaffected soils from three different sites based on greenhouse biotests using a molecular barcoding...
Apple Replant Disease (ARD) is a significant problem in apple orchards that causes root tissue damage, stunted plant growth, and decline fruit quality, size, overall yield. Dysbiosis of root-associated microbiome selective richness Streptomyces species the rhizosphere typically concurs impairment associated with ARD. However, possible roles secondary metabolites within these observations remain unstudied. Therefore, we employed One Strain Many Compounds (OSMAC) approach coupled to...
Apple replant disease (ARD) is a worldwide problem for tree nurseries and orchards leading to reduced plant growth fruit quality. The etiology of this complex phenomenon poorly understood, but shifts the bulk soil rhizosphere microbiome seem play an important role. Since roots are colonized by microbes from rhizosphere, studies endophytic in relation ARD meaningful. In study, culture-independent culture-dependent approaches were used order unravel root apple plants 3, 7, 12 months after...
Apple replant disease affects tree nurseries and apple production globally. After repeated planting in the same soil, roots show accumulation of phytoalexins, stunting, blackening. Recently, we showed that nematodes extracted from replanted soil co-extracted microbes triggered these symptoms, while pathogens or plant-parasitic could not explain early development. To identify nematode-microbe complexes coincide with disease, rootstocks were grown greenhouse soils five sites for eight weeks....
The One Strain Many Compounds approach (OSMAC) is a powerful and comprehensive method that enables the chemo-diversity evaluation of microorganisms. This achieved by variations physicochemical cultivation parameters providing biotic abiotic triggers to mimic microorganisms' natural environment in lab. can reactivate silent biosynthetic routes specific metabolites typically not biosynthesized under standard laboratory conditions. In present study, we combined OSMAC with static headspace...
Over the past years, a number of important traits supporting plant growth have been shown for different strains Priestia megaterium (formerly known as Bacillus megaterium). Here, we report draft genome sequence endophytic bacterial strain B1, which was isolated from surface-sterilized roots apple plants.
Apple replant disease (ARD), also described as soil decline, is known for centuries; however, up to now the ultimate causes are unknown. After replanting plants of same species, characterized by a poor vegetative development, stunted growth and reduced yield in terms quantity quality. For tree nurseries orchards, increasingly problematic sustainable economically feasible solution would be use ARD-tolerant rootstocks. Up now, only few Malus genotypes with tolerance ARD have been hardly any...
