Draft Genome Sequence of the Bacterial Endophyte Priestia megaterium B1, Isolated from Roots of Apple ( Malus domestica ). Microbiology Resource Announcements, 12(6), . doi:10.1128/mra.01172-22

Over the past years, a number of important traits supporting plant growth have been shown for different strains of Priestia megaterium (formerly known as Bacillus megaterium ). Here, we report the draft genome sequence of the endophytic bacterial strain Priestia megaterium B1, which was isolated fro…

Worldwide, tree nurseries and apple orchards are facing the problem of apple replant disease (ARD) which results in growth depression and fruit yield and quality reduction. The etiology of this complex soil-borne disease which persists at the affected sites for decades is still not fully understood,…

Apple replant disease affects tree nurseries and apple production globally. After repeated planting in the same soil, apple roots show accumulation of phytoalexins, stunting, and blackening. Recently, we showed that nematodes extracted from replanted soil and co-extracted microbes triggered these sy…

Apple replant disease is a severe problem in orchards and tree nurseries. Evidence for the involvement of a nematode–microbe disease complex was reported. To search for this complex, plots with a history of apple replanting, and control plots cultivated for the first time with apple were sampled in …

Apple replant disease (ARD) is a worldwide problem for tree nurseries and orchards leading to reduced plant growth and fruit quality. The etiology of this complex phenomenon is poorly understood, but shifts of the bulk soil and rhizosphere microbiome seem to play an important role. Since roots are c…
