Última Characterization of the Arachis (Leguminosae) D genome using fluorescence in situ hybridization (FISH) chromosome markers and total genome DNA hybridization Genet. Mol. Biol. Robledo,Germán; Seijo,Guillermo. Chromosome markers were developed for Arachis glandulifera using fluorescence in situ hybridization (FISH) of the 5S and 45S rRNA genes and heterochromatic 4'-6-diamidino-2-phenylindole (DAPI) positive bands. We used chromosome landmarks identified by these markers to construct the first Arachis species ideogram in which all the homologous chromosomes were precisely identified. The comparison of this ideogram with those published for other Arachis species revealed very poor homeologies with all A and B genome taxa, supporting the special genome constitution (D genome) of A. glandulifera. Genomic affinities were further investigated by dot blot hybridization of biotinylated A. glandulifera total DNA to DNA from several Arachis species, the results...

Bras. Zool. Santos,Natália M.; Ferreira-Neto,Maressa; Artoni,Roberto F.; Vicari,Marcelo R.; Bakkali,Mohammed; Oliveira,Claudio de; Foresti,Fausto. Individual samples from five populations of the characid fish Astyanax scabripinnis (Jenyns, 1842) from the Tietê and Paranapanema river basins (Brazil) were studied. All individuals analyzed presented 50 chromosomes but three different karyotypic forms were observed. Additionally, some individuals of one karyomorph presented a macro supernumerary chromosome. No chromosomal differentiation was observed between males and females in any sample analyzed. C-banding revealed two distinct distribution patterns in these populations in which strong terminally located heterochromatic blocks were detected in the long arms of some chromosomes of the specimens from Cascatinha, Cintra, and Funari streams, whereas populations of the Capão Bonito stream and the Barbosa...
