“…The chromosome number 28 is also found in all sections of the subgenus Erodioidea and in three sections of subgenus Robertium [ 3 , 7 ]. Phylogenetic taxonomic studies have been performed for Geranium for species originating from specific areas as North [ 19 ] and South America [ 5 ], Hawaii [ 20 ], Turkey [ 21 ] and New Zealand [ 6 ]. Phylogeny and historical biogeography in some genera of Geraniaceae also have been studied [ 8 , 16 , 22 ].…”

Breeding programs in ornamentals can be facilitated by integrating knowledge of phylogenetic relatedness of potential parents along with other genomic information. Using AFLP, genetic distances were determined for 59 Geranium genotypes, comprising 55 commercial cultivars of the three subgenera of a total collection of 61 Geranium genotypes. A subgroup of 45 genotypes, including intragroup and intergroup hybrids, were selected and further characterized for genome sizes and chromosome numbers. The variation in genome size ranged from 1.51 ± 0.01 pg/2C to 12.94 ± 0.07 pg/2C. The chromosome numbers ranged from 26 to 108–110 with some hybrids showing an aberrant number of chromosomes based on their parents’ constitution. All chromosome numbers of Geranium are an even number, which presumes that unreduced gametes occur in some cross combinations. Overall, parental difference in genome size and chromosome number were not limiting for cross compatibility. Good crossing compatibility was correlated to a Jaccard similarity coefficient as parameter for parental relatedness of about 0.5. Additionally, parent combinations with high differences in the DNA/chromosome value could not result in a successful cross. We expect that our results will enable breeding programs to overcome crossing barriers and support further breeding initiatives.

“…confertiflorum, have been identified in Kentucky, USA (Jones, 2005). This species is native to eastern North America but is widely distributed throughout the North American continent (Piper, 1906;Small, 1907;Aedo, 2000). Geranium carolinianum has long been considered a weed that grows in disturbed habitats such as roadsides, waste places, gardens, old fields, turfs and fallow and cultivated fields in the United States (Kay and Lees, 1907;Britton, 1918;Spencer, 1976;Haragan, 1991).…”

Identification and characterization of the water gap in physically dormant seeds of Geraniaceae, with special reference to Geranium carolinianum

Dislodgment of swollen 'hinged valve' palisade cells adjacent to the micropyle caused the water gap to open in physically dormant seeds of G. carolinianum, and it was clear that initial water uptake takes place through this gap and not via the chalazal opening as previously reported. This water gap ('hinged valve gap') differs from water gaps previously described for other families in morphology, anatomy and location in the seed coat.

“…Geranium carolinianum L. (Geraniaceae) is a weedy winter annual herb native to North America and naturalized in East Asia, South America, and the Caribbean ( Aedo, 2000 ). In China, it is naturalized along roadsides and in agricultural fields, and is considered an invasive species with minor environmental impacts ( Liu et al, 2006 ).…”

“…Although it is not closely related to the horticultural geranium (genus Pelargonium L’Hér. ex Aiton), genetic resources developed for G. carolinianum are potentially transferable to other Geranium L. species, which includes annuals and perennials that are both native and introduced in North America ( Aedo, 2000 ). Here, we present 12 microsatellite loci developed using targeted enrichment and next-generation sequencing.…”

• Premise of the study: Microsatellite primers were developed for Geranium carolinanum, a North American winter annual herb, for use in population genetic analyses.• Methods and Results: Genomic DNA enriched for repeat-containing fragments was sequenced on the Roche 454 Titanium platform, resulting in 470 primer pairs developed from 1115 microsatellite-containing sequences. A subset of 37 primer pairs was screened for polymorphism across three native and three invasive populations. We identified four monomorphic and eight polymorphic loci. Polymorphic loci contained between two and seven alleles per locus, and mean within-population expected heterozygosity ranged from 0.100 to 0.290. Within populations, observed heterozygosity for individual loci ranged from zero to 0.857, and expected heterozygosity ranged from 0.046 to 0.559.• Conclusions: These microsatellite markers will be useful for future studies of genetic diversity, structure, and mating systems across the geographic range of G. carolinianum, and may be transferable to other closely related species.
