Última Chromosome identification in the Andean common bean accession G19833 (Phaseolus vulgaris L., Fabaceae) Genet. Mol. Biol. Altrock,Sarah; Fonsêca,Artur; Pedrosa-Harand,Andrea. Characterization of all chromosomes of the Andean G19833 bean genotype was carried out by fluorescent in situ hybridization. Eleven single-copy genomic sequences, one for each chromosome, two BACs containing subtelomeric and pericentromeric repeats and the 5S and 45S ribosomal DNA (rDNA) were used as probes. Comparison to the Mesoamerican accession BAT93 showed little divergence, except for additional 45S rDNA sites in four chromosome pairs. Altogether, the results indicated a relative karyotypic stability during the evolution of the Andean and Mesoamerican gene pools of P. vulgaris.

Benzaquem,Denise Corrêa; Feldberg,Eliana; Porto,Jorge Ivan Rebelo; Gross,Maria Claudia; Zuanon,Jansen Alfredo Sampaio. Karyotypes of six cichlid species of the genus Crenicichla were investigated. The species C. cincta, C. inpa, C. reticulata, C. lugubris, and C. cf. johanna were collected from Amazon basin, and C. britskii was collected from the Paraná-Paraguai basin. All of the analysed species showed 2n = 48 chromosomes; however, C. cincta, C. lugubris, C. cf. johanna, and C. britskii had a karyotype formula of 8M-SM+40ST-A, FN = 56, while C. inpa and C. reticulata exhibited the formula 6M-SM+42ST-A, FN = 54. Analysis of active Ag-NORs revealed two NOR-bearing chromosomes in all species; however, theses cistrons were located on different chromosome pairs and/or in different chromosome locations in each species. This condition bears evolutionary significance, since it is... Tipo: Info:eu-repo/semantics/article Palavras-chave: Karyotype; Pike cichlid; Chromosome marker; Amazon.
