Reciprocal and multi-species chromosome BAC painting in crucifers (Brassicaceae).
In crucifer cytogenomics, BAC contigs of Arabidopsis thaliana have been used as probes for comparative chromosome painting among species. Here we successfully tested chromosome-specific BAC contigs of A. thaliana (n = 5) and A. halleri (n = 8) as probes for reciprocal BAC painting. Furthermore, BAC contigs of both Arabidopsis species were applied as multi-species painting probes to a third cruc...
متن کاملGenome Organization and Chromosome Architecture.
How the same DNA sequences can function in the three-dimensional architecture of interphase nucleus, fold in the very compact structure of metaphase chromosomes, and go precisely back to the original interphase architecture in the following cell cycle remains an unresolved question to this day. The solution to this question presented here rests on the correlations that were found to hold betwee...
متن کاملIdentification of Human Chromosome Segments that Have High Homology with Rat Genomic DNA
This study was conducted to determine the location of DNA segment with homology to the rat conserved genomic DNA in human chromosomes. The labeled rat genomic DNA was hybridized with normal human (male) metaphases. The study of 74 metaphases after fluorescence in situ hybridization showed 371 twin-spot signals on human chromosomes. Statistical analysis indicated that the specific accumulation o...
متن کاملNucleotide sequence shows that Bean leafroll virus has a Luteovirus-like genome organization.
The complete nucleotide sequence of the Bean leafroll virus (BLRV) genomic RNA and the termini of its smallest subgenomic RNAs were determined to better understand its mechanisms of gene expression and replication and its phylogenetic position within the Luteoviridae: The number and placement of open reading frames (ORFs) within the BLRV genome was Luteovirus-like. The nucleotide and predicted ...
متن کاملA Karyological Study of Some Murid Rodents (Rodentia: Muridae) of Iran
Family Muridae consists of eight genera and 28 species in Iran. This family shows notable variability of karyological features. In this study, karyological data derived from 11 species of 7 genera of this family of Iran are presented and compared with previously published accounts. The included species were: Mus musculus musculus from Gonbad (2n=40, FN=40) and Birjand (2n=40, FN=38), Rattus nor...
