GENETIC CONrROL OF SYNAPTONEMAL COMPLEXES IN DROSOPHILA MELANOGASTER

AN ovary of an adult female Drosophila melanogaster consists of a parallel cluster of ovarioles, each of which is differentiated into an anterior germarium and a posterior vitellarium (see KOCH, SMITH, and KING 1967, their Figure 1 ) , The vitellarium is composed of a series of interconnected egg chambers which lie in single file. Each chamber is in a more advanced developmental stage than the ...

Genetic analysis of the Shaker gene complex of Drosophila melanogaster.

The Shaker complex (ShC) spans over 350 kb in the 16F region of the X chromosome. It can be dissected by means of aneuploids into three main sections: the maternal effect (ME), the viable (V) and the haplolethal (HL) regions. The mutational analysis of ShC shows a high density of antimorphic mutations among 12 lethal complementation groups in addition to 14 viable alleles. The complex is the st...

Synaptonemal complex and recombination nodules in wild-type Drosophila melanogaster females.

Electron microscope serial section reconstruction analysis of all zygotene-pachytene nuclei of meiotic cells from three wild-type germaria (a subunit of the ovary containing the early meiotic stages arrayed in temporal developmental sequence) of Drosophila melanogaster females corroborates and extends earlier observations (Carpenter 1975a) on the nature and sequence of ultrastructural events oc...

phylogeography and genetic diversity of the lesser mouse- eared bat (myotis blythii) in iran

in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...

Expanding the genetic code of Drosophila melanogaster.

Genetic code expansion for unnatural amino acid mutagenesis has, until recently, been limited to cell culture. We demonstrate the site-specific incorporation of unnatural amino acids into proteins in Drosophila melanogaster at different developmental stages, in specific tissues and in a subset of cells within a tissue. This approach provides a foundation for probing and controlling processes in...
