“…In a single instance a few perithecia were found when a stp culture functioned as the female parent in a cross, but no stp mutants were found among the progeny. Taking this result at face value, it could be concluded that stp was similar to the "minute" cytoplasmic variant of Aspergillus (FAULKNER and ARLETT 1964) or the AC-7 mutant described by MUNETA and SRB (1959), neither of which are normally transmitted through a sexual cross, although AC-7 can be transmitted paternally under certain circumstances. The preferred interpretation with stp, however, is that the single instance of fertility can be attributed to a mosaic cytoplasm.…”

“…Several studies reported that acriflavine can induce mutations in different type of microorganisms (i.e. bacteria, yeast, moulds) (Witkin, 1947;Demerec et al, 1951;Marcovich, 1951;Arlett, 1957;Mejsel and Sokolova, 1960;Faulkner and Arlett, 1964;Morita and Mifuchi, 1965;Ball and Roper, 1966;Kot et al, 1975;Younis et al, 1975;Ali et al, 1978;Rosato and De Azevedo, 1978;Aoki et al, 2005). Acriflavine was also found to inhibit DNA-repair following UV-induced damage in bacteria (Doudney et al, 1964;Likhacheva, 1970;Setlow and Boling, 1970;Harm, 1973) and in human cells (Ben-Hur and Ben-Ishai, 1971;Kleijer et al, 1973).…”

“…These other mutants have many properties which are similar or identical to those of the' red 'variant but they have different extrachromosomal changes which are affected in their own particular way by nuclear gene mutations. This is apparent from the behaviour of two persistently segregating mutants of A. nidulans, the acrifiavine-induced 'minute' variant (Arlett, 1960;Faulkner and Arlett, 1964) and the spontaneously occurring 'purple' cytoplasmic variant (Grindle, 1963). The 'red' variant carrying the wildtype nucleus, W3 is phenotypically stable and it can be maintained easily by cloning.…”
