Phylogenetic analysis identified Penicillium ramulosum and P. ![]() polonicum as potential core rot pathogens. into five clades, including three separate clades for A. Phylogenetic analyses separated the Alternaria spp. Penicillium species were identified through ITS sequencing and partial beta-tubulin polymerase chain reaction – random fragment length polymorphisms (PCR-RFLP) for the samples collected from wet core rot symptoms. Species identity of a selection of samples was confirmed using the endopolygalacturonase (endo-PG) gene, the ITS region, and the anonymous genomic regions (OPA1–3, 2–1), which resulted in the identification of A. in 64% of cases preharvest and 36% postharvest. ![]() Wet core rot was associated with Penicillium spp. ![]() Furthermore, 78% of mouldy core rot causing pathogens were identified as Alternaria spp. were identified morphologically in an average of 70% of infected fruit pre-harvest and 32% postharvest. Initially, dry core rot causing Alternaria spp. isolates (97), associated with pre- and post-harvest apple core rot-symptoms and isolates from potential inoculum sources were identified using molecular methods. Although both genera show specific morphological characteristics, they can be difficult to identify to species level. Pathogens most commonly associated with the disease are Alternaria spp. Morphological and molecular identification of fungi associated with South African apple core rot Morphological and molecular identification of fungi associated with South African apple core rotīasson, Elaine Meitz-Hopkins, Julia Lennox, CherylĬore rot is a major contributor to postharvest losses in apples worldwide. ![]()
