Drosophila willistoni polytene chromosomes . I . Pericentric in - version on X chromosome

چکیده
A first case of polymorphism of a pericentric inversion on X-chromosome was detected in six wild populations of Drosophila willistoni from islands and the mainland of Santa Catarina State, southern Brazil. The high representativeness of this inversion, with frequencies between 10 to 42 % in samples of wild populations from Santa Catarina State, suggests that it could be adaptive and that the establishment of such polymorphism was probably due to crossing over restriction in the chromosomal region involved in the rearrangement.

Drosophila willistoni is a geographically widespread Neotropical species. The genome of strain Gd-H4-1 from Guadeloupe Island (Caribbean) was sequenced in 2007 as part of the 12 Drosophila Genomes Project. The assembled scaffolds were joined based on conserved linkage and assigned to polytene chromosomes based on a handful of genetic and physical markers. This paucity of markers was particularl...
متن کاملThe SU(VAR)3-9/HP1 complex differentially regulates the compaction state and degree of underreplication of X chromosome pericentric heterochromatin in Drosophila melanogaster.
In polytene chromosomes of Drosophila melanogaster, regions of pericentric heterochromatin coalesce to form a compact chromocenter and are highly underreplicated. Focusing on study of X chromosome heterochromatin, we demonstrate that loss of either SU(VAR)3-9 histone methyltransferase activity or HP1 protein differentially affects the compaction of different pericentric regions. Using a set of ...
متن کاملLinker histone H1 is essential for Drosophila development, the establishment of pericentric heterochromatin, and a normal polytene chromosome structure.
We generated mutant alleles of Drosophila melanogaster in which expression of the linker histone H1 can be down-regulated over a wide range by RNAi. When the H1 protein level is reduced to approximately 20% of the level in wild-type larvae, lethality occurs in the late larval - pupal stages of development. Here we show that H1 has an important function in gene regulation within or near heteroch...
متن کاملSu(UR)ES: a gene suppressing DNA underreplication in intercalary and pericentric heterochromatin of Drosophila melanogaster polytene chromosomes.
A genetic locus suppressing DNA underreplication in intercalary heterochromatin (IH) and pericentric heterochromatin (PH) of the polytene chromosomes of Drosophila melanogaster salivary glands, has been described. Found in the In(1)scV2 strain, the mutation, designated as Su(UR)ES, was located on chromosome 3L at position 34. 8 and cytologically mapped to region 68A3-B4. A cytological phenotype...
متن کاملOverexpression of the SuUR gene induces reversible modifications at pericentric, telomeric and intercalary heterochromatin of Drosophila melanogaster polytene chromosomes.
The SuUR (suppressor of underreplication) gene controls late replication and underreplication of DNA in Drosophila melanogaster polytene chromosomes: its mutation suppresses DNA underreplication whereas additional doses of the normal allele strongly enhances underreplication. The SuUR protein is localized in late replicating and underreplicating regions. The N-terminal part of the SuUR protein ...
