The application of molecular markers stands out in studies on the genetic variability of animal and plant species. This tool contributes to studies on the history of some chelonian species, since it takes into consideration their longevity and the endangerment they are often exposed to. The aim of the current study is to perform a quantitative research to document and analyze the development of technological competencies based on the number of patents and scientific articles on the use of molecular markers in studies comprising chelonians. It was done using scientific articles from databases such as Science Direct, Web of Science, SCOPUS and CAPES thesis and dissertation bank, as well as patents recorded in databases such as INPI, WIPO and EPO. The results showed a larger number of scientific articles than patents. There was just one patent registration on the use of molecular markers in turtles; it was deposited in 2011 by a group of Chinese researchers. These indicators show an important scientific gap on this subject, which may be the basis of new studies aimed at better understanding and protecting this animal group.
Key words: Molecular markers, turtles, technological prospecting.
