Transcript mapping and processing of mitochondrial RNA in Dictyostelium discoideum.

abstract：:RAPD markers have been obtained in Cladosporium fulvum, in order to establish a genetic map based on mitotic recombination in this imperfect fungus. Segregation analysis has provided molecular evidence of a high degree of recombination during the parasexual cycle, and of the ploidy level of the parasexual progeny. A m...
