Several luminescent beetle luciferases have been cloned and sequenced, mainly from species of Lampyridae family. Despite many luciferases were cloned, luciferases from different life stages (egg, larva and adult) of the same species were not cloned and compared yet. This study is particularly relevant to better understand the ontogeny and molecular evolution of luciferases and bioluminescence in Coleoptera. For this purpose, beetles species that display different colors in different stages of life are particularly interesting. The Pyrearinus termitilluminans larva presents the most blue-shift bioluminescence among beetles known, and the adult has abdominal and thoracic lanterns that produce yellow and green light, respectively. The larval stage luciferase has been cloned and studies of structure and function already exist. Using molecular biology techniques, we intend to clone and sequence the dorsal and ventral luciferases of this species. The study aims is compare the luciferases of different phases of life and different lanterns as well as to investigate the following aspects: 1) the relationship between structure and colors in elaterid luciferases; 2) ontogeny and molecular evolution of elaterid luciferases.
