Abstract

DNA was amplified from individual fossil pollen grains of Abies spp. (Pinaceae), which have been detected from Pleistocene peaty deposits (at least 150,000 years old). To identify the species of the fossil pollen by DNA analysis, the region indicating the species-specific sequence was searched among extant Abies species and the spacer region between rrn5 and trnR in chloroplast DNA was sequenced for four grains of the fossil pollen. Three pollen samples produced the same sequence as extant Abies species. The sequence for the remaining sample differed from that of extant Abies by one substitution. This study showed not only a successful DNA analysis from a single grain of fossil pollen but also a new method to identify the species of fossil pollen for the pollen analysis field.
