Resolution of an equivocal genetic element in Drosophila melanogaster: organization of the maroon-like locus.
Despite extensive prior study, an understanding of the genetic organization of the maroon-like locus (ma-l:1-64n has been elusive. A large-scale, three-point fine structure recombination experiment is described, wholse results provide documentation for an inexcapable argument that maroon-like is a single element rather than a polycistronic system.
متن کاملBiochemical differences between the mutants Rosy-2 and maroon-like of Drosophila melanogaster.
HE conversion of 2-amino-4-hydroxypteridine into isoxanthopterin in wildtype Drosophila melanogaster has been demonstrated and investigated by several groups (FORREST, GLASSMAN and MITCHELL 1956; HADORN and SCHWINCK 1956; NAWA, TAIRA and SAKAGUCHI 1958). This reaction is catalyzed by an enzyme which will also catalyze the oxidation of hypoxanthine through xanthine into uric acid, xanthopterin i...
متن کاملStudies on genetic organization in higher organisms. II. Complementation and fine structure of the maroon-like locus of Drosophila melanogaster.
Mutants of the maroon-like complex, representative of the five known complementation classes, were subjected to fine structure mapping experiments utilizing a nutritional selective procedure which permits the survival of rare ma-l(+) progeny from large-scale crosses. The analysis provides an internally consistent, unique map, colinear with the complementation map. Noncomplementers exhibit a pol...

متن کاملA mutation with major effects on Drosophila melanogaster sex pheromones.
Sex pheromones are intraspecific chemical signals that are crucial for mate attraction and discrimination. In Drosophila melanogaster, the predominant hydrocarbons on the cuticle of mature female and male flies are radically different and tend to stimulate or inhibit male courtship, respectively. This sexual difference depends largely upon the number of double bonds (one in males and two in fem...
