abstract：:Throughout the eukaryotes, sexual reproduction is an almost universal phenomenon. However, within the Kingdom Fungi, this relationship is not so clear-cut. Fungi exhibit a spectrum of reproductive modes and life-cycles; amongst the better known species, sexual reproduction is often facultative, can be rare, and in ove...
