Abstract Techniques for 1) small-scale isolation of high molecular weight total DNA; 2) heteroduplex mobility assay for screening genotypic diversity; and, 3) identification of polymorphic genetic loci in P. brevicompactum and P. chrysogenum are described. Isolate selection Isolates of Penicillium for genetic studies were collected and stored according to the methods presented in Chapter 2. … Continue reading Chapter 4.
