The phenomenon of mutual aversion between mono-spore
found in higher fungi: primary homothallism, unifactorial heterothallism, and bifactorial heterothallism. REGULATION OFSEXUAL PROGRESSION Since in heterothallic forms sexual progres-sion is almost never initiated unless a mono-karyon is confronted with a second compatible strain, it is evident that the transition from the monokaryotic state to the dikaryotic state is regulated …... of mating-type alleles (see Heterothallism and Selﬁng in Fungi below). HETEROTHALLISM AND SELFING IN FUNGI Genetic mechanisms in such diverse eukaryotes as animals, plants, and fungi have evolved to control reproductive com- patibility, and there can be major implications for their mating systems, i.e., the modes of sexual reproduction that range from self-fertilization to outcrossing.

Allelomorph Heterothallism in the Fungi," of 1949. The available review literature, however, is wanting for a number of reasons. Kniep's review, although beautifully comprehensive at the time of its writing, appeared during the period of most intensive work and consequently lacks much later material which is pertinent to the basic problem of tetrapolarity.

Mating System of the Anther Smut Fungus Microbotryum
Despite obvious heterothallism, self-fertility was occasionally observed in few strains ofC. militaris. These observations indicated that C. militaris behaves as a bipolar heterothallic fungus and requires two mating compatible strains in order to produce regular clubshaped perithecial stromata, a fundamental requirement for its industrial cultivation. adolescence period and its characteristics pdf PRIMARY HOMOTHALLISM-RELATION TO HETEROTHALLISM IN THE REGULATION OF SEXUAL MORPHOGENESIS IN SISTOTREMAl ROBERT C.

- There are two main types of sexual breeding systems in fungi, heterothallism and homothallism. In Ascomycetes, the master regulators of sexual reproduction are the “mating-type” (MAT) genes that reside in MAT loci ( Turgeon & Yoder, 2000 ).
