Amoebae of the acellular slime mold Physarum polycephalum convert to plasmodia both asexually and sexually. Genetic analysis of a mutant that exhibits enhanced asexual plasmodium formation is reported. The mutant carries a single lesion (gad-11) located 12.3 map units from mt, a gene that controls mating specificity in sexual plasmodium formation. The mutation, which was isolated in an mt3 strain, is also expressed in mth and mt4 strains.
多核变形虫这种非细胞黏菌的变形虫既能通过无性方式也能通过有性方式转化为原质团。本文报道了对一种表现出增强的无性原质团形成的突变体的遗传分析。该突变体携带一个单一损伤(gad - 11),位于距mt基因12.3个遗传图距处,mt基因控制性原质团形成中的交配特异性。该突变是在一个mt3菌株中分离得到的,在mth和mt4菌株中也有表达。
