Cytogenetic mapping of H1 histone and ribosomal RNA genes in hybrids between catfish species Pseudoplatystoma corruscans and Pseudoplatystoma reticulatum
(2013-01-01)
A physical chromosome mapping of the H1 histone and 5S and 18S ribosomal RNA (rRNA) genes was performed in interspecific hybrids of Pseudoplatystoma corruscans and P. reticulatum. The results showed that 5S rRNA clusters ...

Diversity of cry genes and genetic characterization of Bacillus thuringiensis isolated from Brazil
(2004-08-01)
Two hundred and eighteen Bacillus thuringiensis isolates from Brazil were characterized by the presence of crystal protein genes by PCR with primers specific to different cry and cyt genes. Among these isolates, 95 were ...

Evolutionary dynamics of rRNA gene clusters in cichlid fish
(Biomed Central Ltd., 2012-10-05)
Background: Among multigene families, ribosomal RNA (rRNA) genes are the most frequently studied and have been explored as cytogenetic markers to study the evolutionary history of karyotypes among animals and plants. In ...
