“…A. glauca and P. parasitica both belong to the Mucoraceae (Zygomycetes). P. parasitica is a fusion biotroph, whereby infection is characterized by the formation of a plasma bridge that allows for a limited cytoplasmic continuum between both fungal species (89,175). A number of nuclei of P. parasitica invade the mycelium of A. glauca, and after several days, these nuclei lyse in the host mycelium (89).…”

“…Successful infection requires the presence of complementary mating types in the different species. Action of both mating types produces trisporic acid, which has been hypothesized to be involved in host/parasite interaction (175).…”

“…Mechanisms are unknown for the processes of DNA transfer, the selectivity of transfer, the basis for the replication, and instability of the transferred genes in the recipient (174). Working hypotheses favor a view in which foreign DNA may enter the nuclei in Absidia via a pathway analogous to transformation, after the nuclei in Parasitella disintegrate, and that the foreign DNA may be maintained unstably as extrachromosomal elements (89,175).…”

Although evidence for horizontal gene transfer (HGT) in eukaryotes remains largely anecdotal, literature on HGT in fungi suggests that it may have been more important in the evolution of fungi than in other eukaryotes. Still, HGT in fungi has not been widely accepted because the mechanisms by which it may occur are unknown, because it is usually not directly observed but rather implied as an outcome, and because there are often equally plausible alternative explanations. Despite these reservations, HGT has been justifiably invoked for a variety of sequences including plasmids, introns, transposons, genes, gene clusters, and even whole chromosomes. In some instances HGT has also been confirmed under experimental conditions. It is this ability to address the phenomenon in an experimental setting that makes fungi well suited as model systems in which to study the mechanisms and consequences of HGT in eukaryotic organisms.

Mycology, the study of fungi, originated as a sub discipline of botany and was a descriptive discipline, largely neglected as an experimental science until the early years of this century. A seminal paper by Blakeslee in 1904 provided evidence for self-incompatibility, termed "heterothallism," and stimulated interest in studies related to the control of sexual reproduction in fungi by mating-type specificities. Soon to follow was the demonstration that sexually reproducing fungi exhibit Mendelian inheritance and that it was possible to conduct formal genetic analysis with fungi. The names Burgeff, Kniep and Lindegren are all associated with this early period of fungal genetics research.These studies and the discovery of penicillin by Fleming, who shared a Nobel Prize in 1945, provided further impetus for experimental research with fungi. Thus, began a period of interest in mutation induction and analysis of mutants for biochemical traits. Such fundamental research, conducted largely with Neurospora crassa, led to the one gene:one enzyme hypothesis and to a second Nobel Prize for fungal research awarded to Beadle and Tatum in 1958. Fundamental research in biochemical genetics was extended to other fungi, especially to Saccharomyces cerevisiae, and by the mid-1960s fungal systems were much favored for studies in eukaryotic molecular biology and were soon able to compete with bacterial systems in the molecular arena.The experimental achievements in research on the genetics and molecular biology of fungi have benefited more generally studies in the related fields of fungal biochemistry, plant pathology, medical mycology, and systematics. Today, there is much interest in the genetic manipulation of fungi for applied research. This current interest in biotechnical genetics has been augmented by the development of DNA-mediated transformation systems in fungi and by an understanding of gene expression and regulation at the molecular level. Applied research initiatives involving fungi extend broadly to areas of interest not only to industry but to agricultural and environmental sciences as well.It is this burgeoning interest in fungi as experimental systems for applied as well as basic research that has prompted publication of this series of books under the title The Mycota. This title knowingly relegates fungi into a separate realm, distinct from that of either plants, animals, or protozoa. For consistency throughout this series of volumes, the names adopted for major groups of fungi (representative genera in parentheses) are as follows:
