ABSTRACT Forty-eight useful new mutations of S. commune were obtained by mutagenesis with N-methyl-N'-nitro-N-nitrosoguanidine. Their requirements and meiotic linkage relationships to each other and previously mapped areas were investigated. Several of these new mutations were incorporated into diploid strains so that the diploids contained at least one marker on every linkage group. Analysis of somatic recombination in these diploids indicated that each meiotic linkage group corresponded to an independent chromosome.

ABSTRACT The recessive gene, mound (mnd), allows the appearance of globose masses of compacted hyphae. Dikaryons of Schizophyllum commune that are heteroallelic for mnd [(mosaic dikaryons: (mnd+ mnd  +)] have been successfully dedikaryotized in cholate-containing medium in order to recover the component nuclear types directly. The relative proportion of the two recovered monokaryotic types shows in all cases a marked deviation from 1:1. Hyphae from nonmound mycelial regions yield monokaryotic types identical to those originally used to form the dikaryons. In hyphae from mound-forming regions, however, homoallelism of the mnd allele has been demonstrated; the nuclear type that formerly contained the mnd  + allele acquired a mnd allele.—The process of internuclear transfer or recombination is unaccompanied by the simultaneous alteration of any additional genetic markers carried by the recipient nucleus. The newly acquired mnd allele segregates in Mendelian fashion in subsequent outcrosses and appears to be chromosomally located. A novel process of somatic recombination, with several features distinct from classical parasexual mitotic recombination, appears to be in operation.

Somatic Recombination

ABSTRACT Two sets of diploid cultures of S. commune were observed for sectoring due to haploidization or recombination. Each set consisted of compatible and common-AB diploids otherwise almost isogenic. One of the sets included two compatible diploids with a large proportion of dikaryotic cells. The sectors were isolated and analysed for evidence of aneuploidy and frequent crossing over to determine whether they arose via mitotic or meiotic-like events. It was found that the recombination process in both common-AB and compatible diploids was predominantly mitotic. However, the compatible diploids which developed a high frequency of dikaryotic components gave some evidence of meiotic-like activity. Thus, compatible mating-type factors are necessary for dikaryosis, but not sufficient in themselves to produce it. In compatible mycelia where dikaryosis does occur, meiotic-like recombination may also occur. It is proposed that both lapse into the dikaryotic state, and meiotic-like recombination was induced by different genes under control of the incompatibility factors. Dikaryosis and meiosis are thus seen as tandem phenomena, neither causal of the other but both induced by action of compatible mating-type factors.

Abstract : Macrofungi or mushroom are cosmopolitan heterotrophic organisms which have a very important ecological role. Information on the presence and description of macrofungi can be used as a reference for conservation steps and future potential utilization. The purpose of this study was to provide  description of macro fungi and their potential utilization at Belitong Island. All macro fungi found were Basidiomycota. The identification results showd there were 11 species of mushrooms, i.e. Chlorophyllum molybdites, Lepiota sp., Marasmius sp., Parasola sp., Phallus indusiatus, Lentinus sp.1, Lentinus sp.2, Microporus sp., Polyporus cf. tricholoma, Russula sp., dan Schizophyllum commune. All mushrooms are decomposer at the study site. Some mushrooms have potential as food, medicine and source of other bioactive compounds. This paper explains how to use macroscopic characters to help the identification of macrofungi.Abstrak : Jamur makro merupakan organisme heterotof kosmopolitan yang memiliki peran ekologis yang sangat penting.
