Factors influencing bacterial dynamics along a transect from supraglacial runoff to proglacial lakes of a high Arctic glacier [corrected].

abstract：:There are an increasing number of assays available for fungal plant pathogens based on DNA technology. We have developed such an assay for Gaeumannomyces graminis var. tritici (Ggt) in soil, using slot-blot hybridisation. To ensure the validity of DNA-based soil assays for the fungus, it is important to determine the ...
