Incidence, Speciation, and Morpho-Genetic Diversity of Penicillium spp. Causing Blue Mold of Stored Pome Fruits in Serbia

Blue mold, caused by spp., is one of the most economically important postharvest diseases of pome fruits, globally.

Description
Summary:Blue mold, caused by spp., is one of the most economically important postharvest diseases of pome fruits, globally. Pome fruits, in particular apple, is the most widely grown pome fruit in Serbia, and the distribution of spp. responsible for postharvest decay is unknown. A two-year survey was conducted in 2014 and 2015, where four pome fruits (apple, pear, quince, and medlar) with blue mold symptoms were collected from 20 storage locations throughout Serbia. Detailed morphological characterization, analysis of virulence in three apple cultivars, and multilocus phylogeny revealed three main spp. in order of abundance: , , and Interestingly, split into two distinct clades with strong statistical support that coincided with several morphological observations. Findings from this study are significant and showed previously undocumented diversity in blue mold fungi responsible for postharvest decay including the first finding of , and as postharvest pathogens of quince and of medlar fruit in the world, and of quince in Serbia. Data from this study provide timely information regarding phenotypic, morphological and genotypic plasticity in that will impact the design of species-specific detection tools and guide the development of blue mold management strategies.
