Location of the LSP-1 Genes in Drosophila Species by IN SITU Hybridization.

Investigation of TEL/AML1 and BCR/ABL Fusion Genes in Patients Affected by Acute Lymphoblastic Leukaemia Using Interphase in situ Hybridization

Broadening Gene Pool of Rice for Resistance to Biotic Stresses Through Wide Hybridization

Variability in the cultivated germplasm for economic traits such as resistance to rice tungro virus, sheathblight, yellow stem borer, drought and salt tolerance is limited. This necessitated search for the genes in secondary and tertiary gene pool of genus Oryza. Fortunately, wild species are an important reservoir ofuseful genes for resistance to major disease, pest and tolerance t...

Retrospective assessment of radiation dose by Fluorescence In Situ Hybridization and evaluation of stable chromosomal aberrations

Estimation of absorbed dose for radiation workers or person involved in different radiological accident is the aim of biodosimetry. Cytogenetic methods are the most current and applicable biodosimetry tools. In chronic or protracted exposure, fluorescence in situ hybridization (FISH), stable chromosomal aberration is used for estimation of absorbed dose. For precise estimation of absorbed dose,...

Location of the 18/28S ribosomal RNA genes in two Hawaiian Drosophila species by monoclonal immunological identification of RNA.DNA hybrids in situ.

Using both heterologous rabbit antisera and mouse monoclonal antibody to RNA.DNA hybrids, we have mapped the in situ hybridization locus of the 18/28S ribosomal RNA fraction to a single large band on polytene autosome 3 in Drosophila heteroneura and Drosophila silvestris. This portion of the chromosome is not physically connected with the nucleolus at the end of larval salivary gland developmen...

Chromosomal localization and partial sequencing of the 18S and 28S ribosomal genes from Bradysia hygida (Diptera: Sciaridae).

In insects, ribosomal genes are usually detected in sex chromosomes, but have also or only been detected in autosomal chromosomes in some cases. Previous results from our research group indicated that in Bradysia hygida, nucleolus organizer regions were associated with heterochromatic regions of the autosomal C chromosome, using the silver impregnation technique. The present study confirmed thi...
