Caracterización genética de la morera de papel (Broussonetia papyrifera (L.) Vent.: Moraceae) mediante marcadores de retrotransposones IRAP y REMAP

The human colonization of the Pacific occurred in two major stages: the first migration took place about 50,000 to 30.000 years before present, and the second stage occurred more recently, about 5.000 to 1.000 years before present. This latter large movement was complex and has been widely studied gathering archeological, linguistic and genetic evidence in order to elucidate questions such as the different routes proposed for the settlement of Oceania. Human samples have been analyzed using genetic tools, but these present several complexities that limit their scope. Therefore studies centered on human-associated species (known as commensal species) arise. Animal and plant species have been studied, and among the latter, paper mulberry (Broussonetia papyrifera), a plant native from Asia and introduced in the Remote Oceania Region has been used a commensal model species. Due to its use as a fiber source to make textiles and the cultural importance of paper mulberry, it is interesting to address the study of this species to contribute to the understanding of migratory routes in Remote Oceania. Molecular markers are the main tools to analyze DNA regions that present genetic diversity. In B. papyrifera, ribosomal and chloroplast DNA regions have been analyzed, finding no genetic diversity in samples from Remote Oceania. An alternative to approach this kind of analysis could be the use of retrotransposon-based markers, which have been reported as ubiquitous and a major source of genetic diversity in plants. Retrotransposon-based markers are Inter-Retrotransposon Amplified Polymorphisms (IRAP) and Retrotransposon-Microsatellite Amplified Polymorphisms (REMAP), among others. IRAP and REMAP amplify regions between Long Terminal Repeats (LTR), or between LTR and microsatellites, respectively. These markers are easy to apply and have been widely used for genetic diversity studies in different plant species. Based on this background, the following hypothesis is proposed: “The study of B. papyrifera by retrotransposon-based markers IRAP and REMAP allow to detect genetic diversity in samples from Remote Oceania not previously differentiated with others molecular markers”. In order to characterize the genetic diversity of B. papyrifera samples from Remote Oceania by IRAP and REMAP, primers were selected from the literature to analyze samples of B. papyrifera from native and introduced areas. First, we checked that the amplified sequences with these primers were obtained from retroelements. Five sequences amplified with an IRAP marker were characterized and shown to correspond to two types of TRIM (Terminal-repeat Retrotransposon In Miniature) elements, which are short retrotransposon derivatives that have some conserved regions characteristic of retroelements, but lack functional open reading frames. Then, protocols for IRAP and REMAP amplification were standardized in order to obtain optimal amplification patterns. In addition, electrophoresis and image capture conditions were defined. From 45 IRAP and 36 REMAP primer combinations, 4 REMAP combinations showed distinct amplification patterns in a reduced group of B. papyrifera samples from Remote Oceania. The results obtained from the analysis of 55 samples of B. papyrifera using four selected REMAP markers showed little diversity, supporting the notion of a clonal dispersal of paper mulberry among Pacific islands. These results complement data obtained with others markers in paper mulberry and other species, and are consistent with the previously proposed models of human colonization of the Pacific as the “fast train” or the “Triple-I” models. The present work is the first retrotransposon study in B. papyrifera and opens the possibility to further work to analyze the clonal dispersal and diversification of paper mulberry in Remote Oceania, considering that retroelements have been described as an important source of molecular diversity in plant species...
