Sexual reproduction in the fungi is extensively regulated by incom patibility, which determines, in the absence of any morphological differ entiation, the pattern of mating among individual strains. Control of the interactions that comprise the sexual reproductive process resides in specific genetic factors, the incompatibility factors, which occur in several distinct systems in the various groups of fungi and which exert their control in two basically different ways. On the one hand, the system may play the same role as dioecy in higher organisms by restricting or preventing inbreeding among the members of the same race (homo genic incompatibility) and thus enhance outbreeding. On the other hand, the system may impose the opposite effect by restricting or preventing interbreeding between members of different races (heterogenic incompatibility) and thus promote inbreeding. In addition to these basic facts concerning the general biological signi ficance of incompatibility, important advances have been made in recent years, especially in the investigation of the genetics of incompatibility systems. Sufficient information concerning the genetic determination of incompatibility is now available to understand many phenomena which were very mysterious in the 1920's, when H. KNIEP, of Wiirzburg, Ger many, laid the groundwork for all subsequent study of incompatibility in the higher fungi. Furthermore, there is at present enough conceptual understanding of the physiological activity of the incompatibility-genes and of their action in morphogenetic processes to permit at least the formulation of plausible models of the operation of incompatibility systems.
Now published by Academic Press and revised from the author's previous Five Kingdoms 3rd edition, this extraordinary, all inclusive catalogue of the world’s living organisms describes the diversity of the major groups, or phyla, of nature’s most inclusive taxa. Developed after consultation with specialists, this modern classification scheme is consistent both with the fossil record and with recent molecular, morphological and metabolic data. Generously illustrated, now in full color, Kingdoms and Domains is remarkably easy to read. It accesses the full range of life forms that still inhabit our planet and logically and explicitly classifies them according to their evolutionary relationships. Definitive characteristics of each phylum are professionally described in ways that, unlike most scientific literature, profoundly respect the needs of educators, students and nature lovers. This work is meant to be of interest to all evolutionists as well as to conservationists, ecologists, genomicists, geographers, microbiologists, museum curators, oceanographers, paleontologists and especially nature lovers whether artists, gardeners or environmental activists.

Kingdoms and Domains is a unique and indispensable reference for anyone intrigued by a planetary phenomenon: the spectacular diversity of life, both microscopic and macroscopic, as we know it only on Earth today.
