Cytogenetic analyses of five amazon lizard species of the subfamilies Teiinae and Tupinambinae and review of karyotyped diversity the family Teiidae

Abstract: Lizards of the family Teiidae (infraorder Scincomorpha) were formerly known as Macroteiidae. There are 13 species of such lizards in the Amazon, in the genera Ameiva (Meyer, 1795), Cnemidophorus (Wagler, 1830), Crocodilurus (Spix, 1825), Dracaena (Daudin, 1801), Kentropyx (Spix, 1825) and Tupinambis (Daudin, 1802). Cytogenetic studies of this group are restricted to karyotype macrostructure. Here we give a compilation of cytogenetic data of the family Teiidae, including classic and molecular cytogenetic analys… Show more

“…1, the 5S rDNA sites are present only on one chromosome pair, which could serve as a protection strategy against transposition events and permutation and could act on dispersion of these sequences [Galetti and Martins, 2004;Martins and Wasko, 2004]. However, this species is in the process of being described, and its phylogenetic relation is still unclear, with special attention being warranted to the total disagreement of cytogenetic data found compared with chromosomal information already described for this teiid species [Carvalho et al, 2015].…”

“…By comparison of the chromosomal location of 5S rDNA with the 18S rDNA (family 45S rDNA) described by Carvalho et al [2015] in the same species (notably, the same individuals were analyzed in these 2 studies), it is clear that these rDNAs have no syntenic position in any species. This feature would prevent chromosomal rearrangements between chromosomes carrying 45S and 5S rDNA sites [Galetti and Martins, 2004;Martins, 2007] and would facilitate the action of different RNA polymerases, because 45S rDNA is transcribed by RNA polymerase I and 5S rDNA is transcribed by RNA polymerase III [Martins, 2007].…”
