Summary
Extensive genetic studies have been undertaken on the control of asexual cell (plasmodial) fusion inDidymium iridis. At least 6 loci control asexual cell fusion and mutual exchange of protoplasm in the Pan. 1 strain. In this study it was determined that labor-saving use of backcrosses provides reliable genetic data which is in accord with more extensive F2 studies. Additional fusion data on 45 Pan. 1 clones are reported and possible biochemical control mechanisms of the fusion loci are discussed.
