Academic Journal
The article analysis the origin and differentiation of sex and nucleolus organizer regions (NOR)-bearing chromosomes by chromosome painting in populations of Characidium to explain their evolution, phylogeny, and biogeography. It is given that a W-specific probe for efficient chromosome painting was isolated by microdissection. The results obtained from dual-color fluorescence in situ hybridization infer the putative evolutionary pathway.

    Background: The Leporinus genus, belonging to the Anostomidae family, is an interesting model for studies of sex chromosome evolution in fish, particularly because of the presence of heteromorphic sex chromosomes only in some species of the genus. In this study we used W chromosome-derived...

    We describe patterns of DNA sequence diversity in a newly identified sex-linked gene, SlX9/SlY9, in Silene latifolia (Caryophyllaceae). The copies on both sex chromosomes seem to be functional, and each maps close to the respective X- and Y-linked copy of another sex-linked gene pair,...

    The genus Erythrinus belongs to the family Erythrinidae, a neotropical fish group. This genus contains only two described species, Erythrinus erythrinus being the most widely distributed in South America. Six samples of this species from five distinct Brazilian localities and one from Argentina...

    Abstract  Chromosomes of Triportheus nematurus, a fish species from family Characidae, were analyzed in order to establish the conventional karyotype, location of C-band positive heterochromatin, Ag-NORs, GC- and AT-rich sites, and mapping of 18S and 5S rDNA with fluorescence...
