| Abstract: | Several spontaneous variants ofSchizophyllum commune, recovered both from unstable diploids and from meiotic progeny, have been found to prevent the conventional pattern of internuclear transfer of the recessive morphological markermnd. These variants, designatedmnd mob, still express the mound phenotype of unregulated hyperplasia in monokaryons and a modified mound phenotype in dikaryons homoallelic formnd. The high incidence ofmnd mob variants (ca. 2.5%) occurring among meiotic progeny of the crossmnd mob+ × mnd+ mob+, together with the failure to obtainmnd+ mob recombinants from crosses betweenmnd mob andmnd+ mob+, suggests some origin other than point mutation as the basis for generatingmnd mob variants. It is proposed thatmob+ is a transposable element closely linked to or withinmnd and that this element might be responsible for the internuclear transfer of themnd locus suggested to occur in the somaticmnd recombinations reported previously in mnd + mnd+] dikaryons. |
