| Sumario: | Ñandú (Rhea americana) and choique (Pterocnemia pennatta) are large, flightless birds native to South America, belonging to order Rheiformes. The aim of this study was to identify the genomic sequences of apolipoprotein type II (apoVLDL-II), a constituent of the very low density lipoprotein targeted to yolk, which transports triglycerides to the growing vitello. We sampled blood from animals belonging to the "rhea breeding in captivity program" of EEA INTA Bariloche, which came from a nucleus formed from wild animal?s eggs. The genomic region of apoVLDL-II was amplified with 2 sets of primers designed on the bases of GenBank sequences of related species. The fragments were cloned, sequenced and analyzed. We found that apoVLDL-II of choique and ñandu has an amino acid identity between 56.6 and 91.5% with the species compared. Phylogenetic analysis of amino acid sequences shows that choique and ñandu, together with emu, form a well supported group. These are the first apolipoprotein sequences reported from these species. The study of productive characters is required to support future progress of the species. |
