Chromosomal mapping of H3 histone and 5S rRNA genes in eight species of Astyanax (Pisces, Characiformes) with different diploid numbers: Syntenic conservation of repetitive genes
(2016-01-17)
The genus Astyanax is widely distributed from the southern United States to northern Patagonia, Argentina. While cytogenetic studies have been performed for this genus, little is known about the histone gene families. The ...
Microsatellite organization in the B Chromosome and A Chromosome complement in Astyanax (Characiformes, Characidae) species
(2016-06-01)
The organization of microsatellites in B and sex chromosomes has been linked to chromosomal evolution in a number of animal groups. Here, the chromosomal organizations of (CA)15, (GA)15, (CG)15, (GACA)4, and (GATA)8 ...
Highly similar morphologies between chromosomes bearing U2 snRNA gene clusters in the group Astyanax Baird and Girard, 1854 (Characiformes, Characidae): An evolutionary approach in species with 2n = 36, 46, 48, and 50
(2016-01-01)
Repetitive sequences and their chromosomal locations have been widely studied in species of the Astyanax genus. However, the chromosomal organization of U2 snDNA remains largely unknown. The aims of this study were to ...
