Multi-pathogen disease caused by Didymella bryoniae and bacteria on Styrian oil pumpkin: microbial ecology and biocontrol
The Styrian oil pumpkin, Cucurbita pepo L. subsp. pepo var. styriaca Greb, is a crop of cultural, medical and commercial importance in Austria but also in other regions of the world, e.g. in China. In the recent years, fruit rot and black rot caused by the ascomycete Didymella bryoniae (Fuckel) Rehm has lead to dramatic yield losses. In the field, the fungal disease was usually associated with characteristic symptoms of bacteriosis. Bacterial pathogens include Erwinia carotovora, Pseudomonas viridiflava, Pseudomonas syringae and Xanthomonas cucurbitae. The high coincidence of fungal and bacterial disease suggests mutualistic effects in pathogenesis. In this study, Styrian oil pumpkin-associated microbial communities with focus on bacterial endophytes were analyzed by microbial fingerprints performed by PCRSingle Strand Conformation Polymorphism analysis (SSCP) and Fluorescence in situ hybridisation (FISH) in combination with confocal laser scanning microscopy.
