Phylogenetic Analysis of the Former Members of Scrophulariaceae

Abstract

Plants which had been classified to the Scrophulariaceae of the Lamiales were recently reclassified. Many of them were moved to the other families of Lamiales according to the DNA sequences of the plastid DNA. Among those, Melampyrum roseum, Phtheirospermum japonicum, Pseudolysimachion undulata, Lindernia crustacea and Mazus pumilus were chosen for phylogenetic analyses. DNA sequences of 18S rRNA gene and ITS1 of those plants were determined and deposited into GenBank (accession numbers GU359046, GU359047, GU359048, GU359049, GU359050, respectively). Analyses of those DNA sequences confirmed the current classification done on the basis of the plastid DNA sequences of Melampyrum roseum, Phtheirospermum japonicum and Pseudolysimachion undulata. However, it was not possible to classify Mazus pumilus and Lindernia crustacea due to discrepancies of analyses data.
