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...

Angiosperm plastid genomes are generally conserved in gene content and order with rates of nucleotide substitutions for protein-coding genes lower than for nuclear protein-coding genes. A few groups have experienced genomic change, and extreme changes in gene content and order are found within the flowering plant family Geraniaceae. The complete plastid genome sequence of Pelargonium X hortorum...

Geraniaceae plastid genomes are highly rearranged, and each of the four genera already sequenced in the family has a distinct genome organization. This study reports plastid genome sequences of six additional species, Francoa sonchifolia, Melianthus villosus, and Viviania marifolia from Geraniales, and Pelargonium alternans, California macrophylla, and Hypseocharis bilobata from Geraniaceae. Th...

Wood of three species of Viviania from Chile was studied. The wood has growth rings, moderately grouped vessels, helical sculpture in vessels, fiber-tracheids with small pits, and various degrees of storying. Axial parenchyma and rays are absent, regardless of age of stem. These facts are in accord with close relationship to other genera of Geraniaceae s.l. Viviania differs from other Geraniace...

Geraniaceae have emerged as a model system for investigating the causes and consequences of variation in plastid and mitochondrial genomes. Incredible structural variation in plastid genomes (plastomes) and highly accelerated evolutionary rates have been reported in selected lineages and functional groups of genes in both plastomes and mitochondrial genomes (mitogenomes), and these phenomena ha...

There are 35 Geranium (Geraniaceae) species recorded in the Flora of Turkey1,2. Some Geranium (Geraniaceae) species are used as antidiabetic, hemostatic, antihemorrhoidal, antidiarrheic and for the treatment of pain, fevers and gastrointestinal ailments3. Leaves of some Geranium species are consumed as food in Anatolia4. Furthermore, tubers of G. tuberosum in Erzurum and aerial parts of G. purp...

Disruption of DNA replication, recombination, and repair (DNA-RRR) systems has been hypothesized to cause highly elevated nucleotide substitution rates and genome rearrangements in the plastids of angiosperms, but this theory remains untested. To investigate nuclear-plastid genome (plastome) coevolution in Geraniaceae, four different measures of plastome complexity (rearrangements, repeats, nuc...

Geraniin and gallic acid were isolated from the alcohol extract of the aerial parts of Erodium glaucophyllum (Geraniaceae). The identity of the compounds was verified through different physical and spectrometric methods. The antibacterial and antifungal activity of geraniin is presented.

We determined female frequency of 23 populations of the gynodioecious Geranium sylvaticum (Geraniaceae) in Finland. We compared our results to previous results on this species from the 1960s in order to reveal putative changes in female frequencies. Because females may be maintained in gynodioecious populations if their seed production or offspring quality is higher than that of hermaphrodites,...
