title: Genetic recombination in Actinoplanes brasiliensis by protoplast fusion.
abstract: Protoplast formation, fusion, and cell regeneration have been achieved with mutant strains of Actinoplanes brasiliensis. Three-, four-, and five-factor crosses have shown genetic recombination among the markers, and a five-factor cross is analyzed and discussed. Possibilities of using protoplast fusion for gene mapping and strain improvement are suggested.
