“…The exact etiology of replanting plant problems is unknown and their nature is complex due to the presence of different biotic and abiotic factors. The correct rootstock selection is more beneficial than soil fumigation in controlling the problem of apple replanting associated with the problem [ 27 ].…”

“…Apple is one of the most widely produced and economically important fruit crops in temperate regions [1]. Apple replant disease (ARD) is a phenomenon in which the plant growth is severely inhibited after replanting apple trees at the same site for many years [2]. There are many complex etiologies that cause ARD, and the possible factors vary between different regions or orchards of the same region [3,4].…”

Background Apple (Malus domestica Borkh.) is an important economic crop. The pathological effects of Fusarium solani, a species complex of soilborne pathogens, on the root systems of apple plants was unknown. It was unclear how mycorrhizal apple seedlings resist infection by F. solani. The transcriptional profiles of mycorrhizal and non-mycorrhizal plants infected by F. solani were compared using RNA-Seq. Results Infection with F. solani significantly reduced the dry weight of apple roots, and the roots of mycorrhizal apple plants were less damaged when the plants were infected with F. solani. They also had enhanced activity of antioxidant enzymes and a reduction in the oxidation of membrane lipids. A total of 1839 differentially expressed genes (DEGs) were obtained after mycorrhizal and non-mycorrhizal apple plants were infected with F. solani. A gene ontogeny (GO) analysis showed that most of the DEGs were involved in the binding of ADP and calcium ions. In addition, based on a MapMan analysis, a large number of DEGs were found to be involved in the response of mycorrhizal plants to stress. Among them, the overexpressed transcription factor MdWRKY40 significantly improved the resistance of the apple ‘Orin’ callus to F. solani and the expression of the resistance gene MdGLU by binding the promoter of MdGLU. Conclusion This paper outlines how the inoculation of apple seedlings roots by arbuscular mycorrhizal fungi responded to infection with F. solani at the transcriptional level. In addition, MdWRKY40 played an important role in the resistance of mycorrhizal apple seedlings to infection with F. solani.

“…We assume that the complex nature of ARD requires more complex measures that affect the interaction between replant soil and plant. Such approaches include e.g., biofertilisation with living organisms or organic fertilisation based on agroecological principles [14,15] or integrated pest management [16]. Soil amendments such as composts or mulches, and also biological soil amendments in form of Mycorrhizae or bacterial, as well as fungal biopesticides [17,18] increasingly gain interest as alternative ARD management strategies.…”

Apple replant disease (ARD) impacts the economic yield of orchards by physiological and morphological suppression of apple trees on replanted soils. The complexity of replant disease caused by a plethora of biological interactions and physical properties of the soil requires complex management strategies to mitigate these effects. Based on expert recommendations, we selected two management strategies linked to agroecological principles of (a) organic fertilisation with a specific mulch composition (MDK) and (b) biofertilisation with arbuscular mycorrhizal and bacterial strains (AMFbac), applied by a composition of existing products. For both management strategies we provide a proof-of-concept, by pot and field experiments. Both treatments have the potential to mitigate ARD effects on plant vigour. ARD effect was fully mitigated by MDK treatment in the short-term (one year) and was mitigated by up to 29% after seven years of MDK treatment (long-term). MDK provides an additional substrate for root growth. AMFbac has the potential to mitigate ARD effects on plant vigour but with non-replicable plant-beneficial effects in its current form of application. Thereby our results show a principal potential to mitigate economic effects but not to overcome replant disease inducing effects. While the MDK treatment is found resource intensive but reliable, the AMFbac treatment was found more user-friendly.
