✦ Synopsis

In Drosophila rnelanogaster there are two glutamine synthetase (GS) (EC 6.3.1.2) isozymes. They are called GSI and GSII. The two enzymes have different subunits and different genetic determination. A DNA fragment that comprises 80% of the coding region of the glutamine synthetase gene of Chinese hamster ovary (CHO) cells allowed the identification and cloning of an homologous DNA fragment of Drosophila. This sequence is located at the 10B8-11 region on the X chromosome. Dose variation of a chromosomal segment from 9F3 to 10C1-2, which encompasses the 10B region, leads to proportional variations of GSII without apparently influencing the amount of GSI.

The possibility that viable male-sterile mutations occur in vital genes and the role played by lethal mutations and viable male-steriles in male gametogenesis were studied. Five sterile loci were identified among the 30 most proximal vital loci of the X-chromosome and two of them were shown to be al
