| Resumo: | Mitotic recombination has been used as a tool for detecting cell differentiation mutants in clones of heterozygous individuals. With this method, previously mutagenized (ethyl methanesulfonate) genomes can be screened for mutants, induced anywhere in the genome, in a first generation, and irrespectively of being lethal themselves or present ina lethal chromosome. Induced mitotic recombination was used again in order to give the chromosome arm location and recombinational locus. In this way 13 new cell differentiation mutants out of 1504 studied genomes have been detected, meiotically mapped and isolated. They affect the process of cell differentiation of chaetes and/or trichomes in the adult cuticle of the thorax and/or the tergites. A mitotic chromosome map has been constructed using the mitotic recombination data of these new mutants and those of other cell differentiation mutants already available. The applicability of this method for the detection of other cell mutants in other systems is discussed. |
