Characterization of the apple and pear bark microbiota

Abstract: Bark is considered an important overwintering site for pathogenic, beneficial and saprophytic microorganisms and can act as a reservoir of potential plant pathogens and biocontrol agents. However, the majority of the studies regarding plant-associated microbial communities are focused on the phylloplane, fruits and the rhizosphere, while bark is poorly investigated. The aim of this study was to assess the composition of fungal and bacterial communities of pear and apple barks. Results showed that the amount of cultivable colony forming units (CFUs) and the composition of fungal and bacterial communities differed according to bark age and plant species.
