Mechanism of hycanthone mutagenesis: the induction of temperature-sensitive mutations in Drosophila melanogaster. 1977

P G Kramers

A total of 358 sex-linked recessive lethals induced by hycanthone methane sulphonate (HMS) were checked for temperature sensitivity, along with 239 EMS-induced lethals as a positive control. Only about 1-2% of the HMS-induced lethals were temperature-sensitive, in contrast to about 7-8% for EMS-induced lethals. This can be reasonably explained by assuming that in Drosophila, HMS mainly acts by inducing frame-shift mutations or deletions.

UI MeSH Term Description Entries
D009154 Mutation Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations. Mutations
D004331 Drosophila melanogaster A species of fruit fly frequently used in genetics because of the large size of its chromosomes. D. melanogaster,Drosophila melanogasters,melanogaster, Drosophila
D005804 Genes, Lethal Genes whose loss of function or gain of function MUTATION leads to the death of the carrier prior to maturity. They may be essential genes (GENES, ESSENTIAL) required for viability, or genes which cause a block of function of an essential gene at a time when the essential gene function is required for viability. Alleles, Lethal,Allele, Lethal,Gene, Lethal,Lethal Allele,Lethal Alleles,Lethal Gene,Lethal Genes
D006826 Hycanthone Potentially toxic, but effective antischistosomal agent, it is a metabolite of LUCANTHONE.
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D013696 Temperature The property of objects that determines the direction of heat flow when they are placed in direct thermal contact. The temperature is the energy of microscopic motions (vibrational and translational) of the particles of atoms. Temperatures
D013892 Thioxanthenes Compounds with three aromatic rings in linear arrangement with a SULFUR in the center ring.
