The hfa (high frequency of aneuploidy) mutants of Aspergillus nidulans carry conditional lethal (temperature-sensitive) defects which cause an increased frequency of aneuploids to be produced amongst their asexual progeny. When examined microscopical

Spontaneous mutant strains of Phytophthora infestans resistant to either streptomycin or chloramphenicol were selected by prolonged exposure of colonies to drug-amended media. Each strain was then crossed with a sensitive strain having different RFLP

The mitotic and meiotic stabilities of transgenes were evaluated in the oomycete, Phytophthora infestans. Genes encoding beta-glucuronidase (GUS), neomycin phosphotransferase (NPT) and hygromycin phosphotransferase (HPT), fused to one of six promoter

Mature (three-week) and immature (five-day) sexual progeny were raised from two matings between isolates of Phytophthora infestans with 2C-DNA content (and therefore presumed diploids) but which differed for isozyme genotype and restriction fragment

The duplication cycle of nuclei in germinating zoospores of Phytophthora infestans was determined. One isolate, a presumed diploid, had a duplication cycle of 7–8 h, whereas a presumed tetraploid isolate had a cycle of 10–12 h. Nuclei from uninuc

Sexual progeny were raised from matings between 2C (diploid) × 4C (tetraploid), 2C × 2C and 4C × 4C isolates of Phytophthora infestans. The percentage germination of oospores and establishment of colonies were generally lower in the 2C × 4C and 4

Strains of Aspergillus nidulans carrying the conditional-lethal mutation sod VI C1 (stabilization of disomy) are defective in nuclear division and hyphal extension. The mutation affects both the establishment and maintenance of polar growth, since mu
