| Research Abstract |
This study attempted to develop a method to identify the pollen grain at species level by analyzing its DNA in order to define a provenance of the pollen that can be found in Antarctic snow and ice. For the development, Pinus pollen grains extracted from a glacier in Russia was analyzed as a preliminary approach. Pinus pollen is a major type(> 50%) of pollen in Antarctic snow and ice. Modern pollen analysis observes pollen morphology with a microscope, identification of Pinus pollen is limited to genus level only. This study allowed us to identify the pollen at subsection level that is one rank higher of species.
