ΜΕΛΕΤΗ ΤΩΝ ΠΟΛΥΤΑΙΝΙΚΩΝ ΧΡΩΜΟΣΩΜΑΤΩΝ ΤΩΝ ΚΥΤΤΑΡΩΝ ΤΩΝ ΣΙΑΛΟΓΟΝΩΝ ΑΔΕΝΩΝ ΤΗΣ DROSOPHILA AURARIA

DROSOPHILA AURARIA AND ITS SIBLING SPECIES D. BIAURARIA, D. QUADRARIA AND D. TRIAURARIA ARE UNIQUE AMONG DROSOPHILA SPECIES IN THAT THEIR SALIVARY GLAND CHROMOSOMES EXHIBIT BALBIANI RING (BRS). WE PRESENT HERE A CYTOLOGICAL MAP OF D. AURARIA AND INFORMATION ON THE DEVELOPMENTAL PROFILES OF ITS PUFFS AND BRS. AUTORADIOGRAPHY HAS BEEN PERFORMED IN ORDER TO CONFIRM THE RNA SYNTHESIS OF THE BRS DURING DEVELOPMENT. INFORMATION IS PRESENTED ON THE EXISTENCE OF TANDEM INVERTED DUPLICATIONS INVOLVING THE BRS REGIONS AND OTHERS OF THE CHROMOSOMES, AND DATA ARE GIVEN CONCERNING THE PUFFING PATTERNS OF THE DUPLICATED BONDS. THE INTERCALARY HETEROCHROMATIN SITES OF THE GENOMA ARE GIVEN, AND THE POSSIBLE ROLE OF THEIR TYPE OF HETEROCHROMATIN ARE DISCUSSED. POSSIBLE HOMOLOGIES BETWEEN PUFFS OF D. MELANOGASTER AND D. AURARIA AND CERTAIN DIFFERENCIES BETWEEN THE TWO SPECIES IN THE DEVELOPMENTAL SEQUENCES OF THE ACTIVA LOCI ARE ALSO DISCUSSED.
