Characteristics of NOR-banded chromosomes of Mangalarga horses
The nucleolar organizer regions (NORs) of Mangalarga horses were characterized by analysis of NOR-banded metaphase chromosomes according to the technique of Goodpasture and Bloom (Chromosoma 53: 37-50, 1975). NOR banding ...
Paracentric inversion involving a NOR-bearing chromosome of rainbow trout (Oncorhyncus mykiss): Electron microscopy studies of the synaptonemal complex
Cytogenetic studies conduced on a sample of 19 specimens of rainbow trout (Oncorhyncus mykiss) showed that 6 presented two chromosomes with a single subterminal AgNOR on the short arms and 13 presented one chromosome with ...
Analysis of NOR distribution in cultivated and naturalized stocks of rainbow trout (Oncorhynchus mykiss)
(Sociedade Brasileira de Genética, 2002-01-01)
In salmonid species, nucleolar organizing regions (NORs) have frequently been found on a single chromosome pair. However, some other, smaller yet active NORs have also been described. In the present study, NORs were found ...
NUCLEOLAR CHROMOSOME VARIANTS IN STERNOPYGUS-MACRURUS (PISCES, STERNOPYGIDAE) FROM 3 BRAZILIAN RIVER BASINS
(Univ Florence Botany Inst, 1993-01-01)
The karyotypes, location of nucleolus organizer regions (NOR) and constitutive heterochromatin pattern of Sternopygus macrurus (Pisces, Gymnotoidei) of natural populations from the Amazon River, Sao Francisco River and ...
Seco-, nor-, normal and rearranged labdanes from Haplopappus parvifolius
The aerial parts of Haplopappus parvifolius afforded 30 new diterpenes including 21 labdane derivatives, four nor-diterpenes, three rearranged ones, four seco-labdanes and one with a new carbon skeleton whose structure was ...

Karyotype and NOR conservatism with heterochromatin reorganization in Neotropical Bryconids
Cytogenetic studies on Bryconid fishes have shown the occurrence of karyotype and NOR conservatism and heterochromatin reorganization. The present data on three species representative of the migratory genus Brycon corroborate ...
