متن کاملPhotosystem II gene sequences of psbB and psbC clarify the phylogenetic position of Vanilla (Vanilloideae, Orchidaceae)
Nucleotide sequences of the plastid genes psbB and psbC were obtained for 34 taxa to represent most genera currently classified within Vanilloideae (Orchidaceae). These genes code for two of the subunits that make up the Photosystem II protein P680, and have only rarely been used for reconstructing phylogenetic relationships among plants. We failed to amplify psbB from the achlorophyllous gener...
متن کاملThe taxonomic identity of three varieties of Lecanorchis nigricans (Vanilleae, Vanilloideae, Orchidaceae) in Japan
To elucidate the taxonomy of the Lecanorchis nigricans Honda, 1931 species complex, the present study investigated the detailed morphology of three L. nigricans varieties in Japan. While L. nigricans var. patipetala Y.Sawa, 1980 and L. nigricans var. yakusimensis T.Hashim., 1990 have often been treated as synonyms of L. nigricans var. nigricans, the present study demonstrates that the three var...
