Phylogeny and Historical Biogeography of Geraniaceae in Relation to Climate Changes
Chloroplast (trnL–F and rbcL) sequences were used to reconstruct the phylogeny of Geraniaceae and Hypseocharitaceae. According to these data Hypseocharitaceae and Geraniaceae are monophyletic. Pelargonium and Monsonia are sisters to the largest clade of Geraniaceae, formed by Geranium, Erodium and California. According to molecular dating and dispersal-vicariance analysis, the split of the stem...
متن کاملMitochondrial and Chloroplast Dna-based Phylogeny of Pelargonium (geraniaceae)1
Overall phylogenetic relationships within the genus Pelargonium (Geraniaceae) were inferred based on DNA sequences from mitochondrial(mt)-encoded nad1 b/c exons and from chloroplast(cp)-encoded trnL (UAA) 59 exon–trnF (GAA) exon regions using two species of Geranium and Sarcocaulon vanderetiae as outgroups. The group II intron between nad1 exons b and c was found to be absent from the Pelargoni...
متن کاملGenus-Wide Screening Reveals Four Distinct Types of Structural Plastid Genome Organization in Pelargonium (Geraniaceae)
Geraniaceae are known for their unusual plastid genomes (plastomes), with the genus Pelargonium being most conspicuous with regard to plastome size and gene organization as judged by the sequenced plastomes of P. x hortorum and P. alternans. However, the hybrid origin of P. x hortorum and the uncertain phylogenetic position of P. alternans obscure the events that led to these extraordinary plas...
متن کاملMitochondrial and chloroplast DNA-based phylogeny of Pelargonium (Geraniaceae).
Overall phylogenetic relationships within the genus Pelargonium (Geraniaceae) were inferred based on DNA sequences from mitochondrial(mt)-encoded nad1 b/c exons and from chloroplast(cp)-encoded trnL (UAA) 5' exon-trnF (GAA) exon regions using two species of Geranium and Sarcocaulon vanderetiae as outgroups. The group II intron between nad1 exons b and c was found to be absent from the Pelargoni...
متن کاملDiversity and Evolution of Seedling Baupläne in Perlargonium (Geraniaceae)
The genus Pelargonium (Geraniaceae) exhibits tremendous variation in growth form. We apply a broadly defined concept of Bauplan in our study of growth form, architectural and anatomical features of early seedling development in the type subgenus. We analyze variation in these features within a phylogenetic framework based on sequence comparisons of internal transcribed spacer regions (ITS) of n...
