Cytogenetic Analysis of Histone Gene and DNA Methylation in Amazonian Turtles (Chelonia: Podocnemididae) [PDF]
ACS OmegaHistone genes contain sequences responsible for coding five types of proteins (H1, H2A, H2B, H3, and H4) that are of great importance for chromatin organization. Their transcriptional regulation through DNA methylation has been little studied. Testudines are ancient reptiles with high cytogenetic diversity (2n = 26-68), with a large number of histone ...

Physical mapping of repetitive DNA suggests 2n reduction in Amazon turtles Podocnemis (Testudines: Podocnemididae). [PDF]
PLoS ONE, 2018 Cytogenetic studies show that there is great karyotypic diversity in order Testudines (2n = 26-68), and that this may be mainly attributed to the presence/absence of microchromosomes. Members of the Podocnemididae family have the smallest diploid numbers
