| Abstract: | Studies on the population biology of the chestnut blight fungus, Cryphonectria parasitica, have previously been carried out with dominant restriction fragment length polymorphism (RFLP) fingerprinting markers. In this study, we describe the development of 11 codominant markers from randomly amplified polymorphic DNAs (RAPDs). RAPD fragments were cloned and sequenced, and polymerase chain reaction (PCR) primers were designed flanking insertions/deletions. Primers labelled with fluorescent dyes were combined in multiplex reactions to assay five or six loci simultaneously in a capillary sequencing system. These codominant markers have the potential to complement RFLP methods for studying C. parasitica. |
