“…In this context, previous studies of rDNA using the ITS support the O. tuberosa alliance hypothesis (Tosto and Hopp, 1996;Emshwiller and Doyle, 1998). The naturalness of the group has been also supported by other studies based on the chloroplast-expressed glutamine synthetase (Emshwiller and Doyle, 1999;Emshwiller and Doyle, 2002) and AFLPs (Tosto and Hopp, 2000).…”

“…The GAPDH gene was amplified with primers GPDX7F and GPDX11R , while GScp687f and GScp994r primers (Emshwiller and Doyle 1999) were used to amplify the ncpGS gene. The trnL-F region was amplified with the universal primers ''c'' and ''f' ' (Taberlet et al 1991), and the psbA-trnH region was amplified with trnH (GUG) and psbA primers (Hamilton 1999).…”

Untangling the hybrid origin of the Chinese tea roses: evidence from DNA sequences of single-copy nuclear and chloroplast genes

et al. 2011

The tea-scented China roses largely correspond to the three recognized double-petaled Rosa odorata (Andrews) Sweet (Rosoideae, Rosaceae) varieties, which are the ancestors of modern hybrid tea roses and had a definite and permanent influence on the evolution of modern garden roses. Here the hypothesis of a hybrid origin of the tea-scented China roses between R. odorata var. gigantea and R. chinensis was tested. Two single-copy nuclear genes of the cytosolic glyceraldehyde 3-phosphate dehydrogenase (GAPDH) and the chloroplast-expressed glutamine synthetase (ncpGS) together with two plastid loci (trnL-F and psbA-trnH) were sequenced for representative accessions of four R. odorata varieties, R. chinensis, and 28 other Rosa species. Phylogenetic relationships were estimated from two nuclear loci using maximum parsimony and Bayesian analyses, and a haplotype network was constructed on the combined plastid data using NETWORK. For GAPDH and ncpGS loci, the clonal sequences of the three double-petaled varieties were clustered into two clades, one clade with R. odorata var. gigantea, and the other with partial sequences of R. chinensis, which suggested that the tea-scented China roses were hybrids between R. odorata var. gigantea and R. chinensis. Two plastid loci suggested that R. odorata var. gigantea could be the maternal parent and R. chinensis the paternal parent.

“…Molecular characters selected for this analysis were those shown to resolve species-level phylogenetic relationships in other monocot groups or similar taxonomic levels (intra-familial) of analysis (Sang et al 1997;Graham et al 1998;Mason-Gamer et al 1998;Emshwiller and Doyle 1999;Tank and Sang 2001;Kress et al 2002;Lewis and Doyle 2002). Characters were sampled from multiple genomes in order to enable the identification of any conflicting signal from potential hybridization events and to incorporate whole organismal history.…”

ABSTRACT.A phylogenetic analysis of molecular (ITS, trnL-F, trnK including the matK coding region) and morphological data is presented for the pantropical monocot family Costaceae (Zingiberales), including 65 Costaceae taxa and two species of the outgroup genus Siphonochilus (Zingiberaceae). Taxon sampling included all four currently described genera in order to test the monophyly of previously proposed taxonomic groups. Sampling was further designed to encompass geographical and morphological diversity of the family to identify trends in biogeographic patterns and morphological character evolution. Phylogenetic analysis of the combined data reveals three major clades with discrete biogeographic distribution: (1) South American, (2) Asian, and (3)
