The tail of the Brazilian gekkonid lizard, Lygodactylus klugei, exhibits a suite of characteristics associated with both tail retention and tail loss adaptations. Tails are specialized for locomotion, possess specialized cutaneous glands, and are high in lipid and energy content. Tail loss in a natural population, however, is high and presumably associated with escape from predation via tail autotomy. The importance of the presence of a complete tail both functionally and for future predator escape is reflected by rapid regeneration of a tail complete with specialized functionally important structures.

Horizontal gene transfer (HGT)- is defined as the acquisition of genetic material from another organism. However, recent findings indicate a possible role of HGT in the acquisition of traits with adaptive significance, suggesting that HGT is an important driving force in the evolution of eukaryotes as well as prokaryotes. It has been noted that, in eukaryotes, HGT is more prevalent than originally thought. Mitochondria and chloroplasts lost a large number of genes after their respective endosymbiotic events occurred. Even after this major content loss, organelle genomes still continue to lose their own genes. Many of these are subsequently acquired by intracellular gene transfer from the original plastid. The aim of our review was to elucidate the role of chloroplasts in the transfer of genes. This review also explores gene transfer involving mitochondrial and nuclear genomes, though recent studies indicate that chloroplast genomes are far more active in HGT as compared to these other two DNA-containing cellular compartments.
