Somatic recombination in Schizophyllum commune.
A CONSIDERABLE effort has been put forth in the past few years to elucidate the mechanisms of internuclear genetic exchange in vegetative mycelia in the fungi (PONTECORVO 1956; RAPER 1959; DAY 1960a). PONTECORVO (1956) described a system whereby, following the formation of a heterokaryon and a diploid nucleus, the phenomenon of crossing-over was a process distinct from that of haploidization. C...
متن کاملGenetic Control of Recombination in SCHIZOPHYLLUM COMMUNE: Location of a Gene Controlling B-Factor Recombination.
In S. commune the frequency of recombination between the two subunits, alpha and beta, of the B incompatibility factor is genetically controlled. Analysis of the progeny obtained from crosses between high- and low-recombining strains indicates that the gene controlling recombination frequency in the B factor is linked to the B factor itself, approximately nine map units from Bbeta. This gene, c...
متن کاملMeiotic-like Recombination in Vegetative Dikaryons of SCHIZOPHYLLUM COMMUNE.
A total of 65 Schizophyllum commune dikaryons of three different genotypes were synthesized, maintained on agar plates, prevented from fruiting, and macerated. The macerate was plated. Germlings of homokaryotic morphology were isolated using no chemical or genetic selection, grown, and tested for recombinant genotypes. Crossover types were plentiful among the homokaryons with recombinant genoty...
متن کاملFruiting Dikaryon of Schizophyllum commune
The patterns of polypeptides synthesized by two co-isogenic monokaryons and the derived dikaryon of the basidiomycete Schizophyflum commune, growing in surface culture, were compared by two-dimensional PAGE after labelling with [35S]sulphate. Synthesis of most of the polypeptides (400 analysed) was common but at day 3 some 30 polypeptides were synthesized in the dikaryon which were not seen in ...
متن کاملThe Genetics of Schizophyllum Commune.
URING the course of an investigation on sexuality and related phenomena Din the common wood-rotting mushroom, Schizophyllum commune, a continuing search has been maintained for appropriate genetic markers for use in the work. A wide variety of morphologically aberrant and biochemically deficient strains has accordingly been tested for single locus segregation and for possible linkage with the f...
