Mahnkopp-Dirks F., Radl V., Kublik S., Gschwendtner S., Schloter M., Winkelmann T. (2021). Molecular Barcoding Reveals the Genus Streptomyces as Associated Root Endophytes of Apple (Malus domestica) Plants Grown in Soils Affected by Apple Replant Disease. Phytobiomes Journal, 5(2), 177-189. doi:10.1094/pbiomes-07-20-0053-r

Apple replant disease (ARD) occurs when apple is repeatedly planted at the same site, leading to growth reductions and losses in fruit yield and quality. Up to now, the etiology has been poorly understood; however, soil (micro)biota are known to be involved. Because endophytes often colonize plants …

Apple Replant Disease (ARD) is a significant problem in apple orchards that causes root tissue damage, stunted plant growth, and decline in fruit quality, size, and overall yield. Dysbiosis of apple root-associated microbiome and selective richness of Streptomyces species in the rhizosphere typicall…

Root exposure to apple replant disease soil triggers local defense response and rhizoplane microbiome dysbiosis. FEMS Microbiology Ecology, (), . doi:10.1093/femsec/fiab031

A soil column split-root experiment was designed to investigate the ability of apple replant disease (ARD) causing agents to spread in soil. ‘M26’ apple rootstocks grew into a top layer of Control soil, followed by a barrier-free split-soil layer (Control soil/ARD soil). We observed a severely reduc…

Split-root approach reveals localized root responses towards apple replant disease (ARD) in terms of ARD biomarker gene expression and content of phenolic compounds. Scientia Horticulturae, 286(), 110117. doi:10.1016/j.scienta.2021.110117

Apple replant disease (ARD) is a threat to apple fruit and tree production worldwide caused by shifts in the soil microbiome. Chemical and physical measures of soil disinfection are the most employed countermeasures but inter-row plantings demonstrate that ARD is widely immobile in the soil, which c…

The soil-borne apple replant disease (ARD) is caused by biotic agents and affected by abiotic properties. There is evidence for the interrelation of the soil fungal population and soil aggregate structure. The aim of this study conducted between March and October 2020 on an orchard in north-east Ger…

ABSTRACT Apple replant disease (ARD) occurs worldwide in apple orchards and nurseries and leads to a severe growth and productivity decline. Despite research on the topic, its causality remains unclear. In a split-root experiment, we grew ARD-susceptible ‘M26’ apple rootstocks in different substrat…

Apple replant disease (ARD) is a serious threat to producers of apple trees and fruits worldwide. The ARD etiology is not unraveled and managing options are either economically not applicable or environmentally harmful. Thus, interest is given in biomarkers that allow to indicate ARD situations at e…
