Sequencing pollen DNA to discover insect migratory routes
(PHYSorg.com Biology)

Metabarcoding, a technique of mass DNA sequencing, allows for tracing migratory routes of insects, an understudied subject due to technical limitations. A small DNA fragment of the pollen that insects transport is used as a barcode to identify the plant species they visited previously. A new study shows that transcontinental pollination mediated by migrating insects is possible and, therefore, various plants located very far apart can mix.
