The pPongy2 cladogram. Fast Minimum Dendrogram edited by NCBI server (Altschul et al., 1997) shows the spread among-and-within species of RT (reverse transcriptase) gene of pPongy2, a Ty3-gypsy-like LTR-retrotrasnposon though the evolutionary lineage of gymnosperms from Gingo → Podocarpus (248 My) → Araucaria (230 My) → Taxus (206 My) → Pinaceae (180 My). Genetic distance (scale 0.005) and branch length are indicated, and gymnosperm species are labeled with different color symbols. The accession numbers of taxon included in analyses were Araucaria araucana (AJ290651, AJ290652, AJ290653, AJ290654, AJ290655), Ginkgo biloba (AJ290656), Picea abies (AJ290585, AJ290586, AJ290591, AJ290592, AJ290593, AJ290594), Pinus pinaster (AJ290605, AJ290606), Pinus pumila (AJ290616), Pinus sibirica (AJ290623, AJ290626, AJ290629, AJ290630, AJ290631), Podocarpus totara (AJ290647, AJ290648, AJ290649, AJ290650), Taxus baccata (AJ290640, AJ290641, AJ290642, AJ290643, AJ290644, AJ290645).
