Genetic Manipulation of Fungi by DNA-Mediated Transformationnsformation procedures, genetic manipulation of fungi was dependent almost exclusively upon completion of a sexual cycle and was based upon an analysis of recombination by way of meiotic products (Fincham et al. 1979; Bennett and Lasure 1991). Despite the varied and often extravagant sexual cycles e

Gene Regulation in Yeastenvironmental conditions. This may involve adaptation to different carbon sources or the requirement to use alternative metabolic pathways to overcome a nutrient-limiting condition. Regulation is further required in both microorganisms and higher eukaryotes to realize developmental programs. These m

NOTCH

Gene Regulation in Mycelial Fungio because of the study of evolutionary events and the use of fungi as model systems to investigate biological phenomena in eukaryotes. In contrast to yeast, ., not much is known about the regulation of gene expression in other fungi (see Chap. 9, this Vol.). The reason for this was the relatively la

Plasmid DNA and the Killer Phenomenon in ,long recognized as extrachromosomal circular DNA. The 2-.m DNA of ., the first eukaryote plasmid, as well as many other eukaryotic and prokaryotic plastids, was also found to be circular DNA (Esser et al. 1986; Volkert et al. 1989). The general notion of plasmids being circular was first undermined

Viral RNA and the Killer Phenomenon of ,ovirus-like elements (Tyl,..., Ty5), referred to as retro-transposons. Most strains carry all of these elements in spite of the fact that none is known to have a natural extracellular route of infection. This may be a reflection of the fact that ., like many other fungi, mate frequently in nature so

Yeast Retrotransposonsas provided novel insights and ideas on the relationship between retroelements and their host organism. Initially, much of the interest in retroelements clearly stemmed from their obvious similarity to retro-viruses. Because of increased funding for research on human deficiency virus (HIV), the curr

Biotechnical Genetics of Antibiotic Biosynthesissubstances” refers to molecules of at most a few thousand daltons and does not include those complex proteins that also have antibacterial properties (Lancini and Parenti 1982). Antibiotics include not only antibacterial substances but also compounds with antifungal, antitumour, antiviral etc. activ
