Molecular characterization of imidazolinone-resistant Brassica rapa × B. napus hybrids
(Springer, 2020-12-04)
Herbicide-resistant oilseed rape (Brassica napus) cultivation in our country entails the risk of gene transfer to related wild species. One of these species is the wild turnip (B. rapa), an important weed of winter crops ...
Cromossomos B no gênero Partamona (Hymenoptera: Apidae: Meliponini) : ocorrência, transmissão e origem
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Genética Evolutiva e Biologia Molecular - PPGGEvCâmpus São Carlos, 2016-02-26)
Partamona (Schwarz, 1939) is a stingless bee genus which has as an interesting trait, the presence of B chromosomes in some species. These chromosomes were identified in six closely related species so far, all included in ...
Possible interspecific origin of the B chromosome of Hypsiboas albopunctatus (Spix, 1824) (Anura, Hylidae), revealed by microdissection, chromosome painting, and reverse hybridisation
(2014-01-01)
The B chromosome in the hylid Hypsiboas albopunctatus (2n = 22 + B) is small, almost entirely composed of C-positive heterochromatin, and does not pair with any chromosome of the A complement. B probe, obtained by ...

Repetitive DNA sequences and evolution of ZZ/ZW sex chromosomes in characidium (teleostei: characiformes)
(Public Library Science, 2015)
Characidium constitutes an interesting model for cytogenetic studies, since a large degree of karyotype variation has been detected in this group, like the presence/absence of sex and supernumerary chromosomes and variable ...
