Regeneration, DNA Methylation, and Transformation in Rosaceae
The effects of different concentrations of kanamycin, carbencillin, cefotaxime, and combinations of carbencillin and cefotaxime on regeneration from different tissues of rose (Rosa hybrida cv. Carefree Beauty) were investigated. Agrobacerium tumefaciens strain GV3101 containing pCAMBIA 2301 plasmid …

Systematics of the genus Cliffortia L. [Rosaceae]
… of the Mediterranean climate floras. Cliffortia (Rosaceae) is one of the ten largest genera within the Cape Flora with 117 species currently recognised, 104 of which are endemic to the region. I investigate the processes that have driven the diversification of Cliffortia within the Cape Floristic …

The systematics of Leptosphaeria species found on the Rosaceae
… described from plants in the family Rosaceae. In doing so, a narrow concept of Leptosphaeria based on its type species is substantiated and strengthened. The characteristics of superficial ascocarps with scleroplectenchymatous wall cells and ascospores which are fusiform, …

Genetic Diversity in Native and Invasive <i>Rubus </i>(Rosaceae)
… which species may become invasive. Rubus (Rosaceae) was chosen for study because this genus includes various ploidy levels, reproductive modes, and species that are invasive as well as native. Three Rubus species were chosen to represent apomictic and tetraploid invasives (Rubus …

Relationships among <i>Rubus</i> (Rosaceae) Species used in Traditional Chinese Medicine
… multiple species of the genus <em>Rubus</em> (Rosaceae). Fruits and other parts of <em>Rubus</em> plants have had a significant effect on human health and nutrition in both ancient and modern times. The pharmacological effects of <em>Rubus </em>include anti-inflammatory, antibacterial, …

Clarification of basal relationships in Rubus (Rosaceae) and the origin of Rubus chamaemorus
Determination of phylogenetic relationships among ancestral species of Rubus has been elusive. Most Rubus species (including blackberries and raspberries), representing nine of the 12 subgenera, occur in a large, well supported clade named 'A' for reference). The remaining nine species are excluded …

The biology of Rosa multiflora (Rosaceae) and two of its biotic mortality factors
<p>Rosa multiflora Thunb. (Rosaceae), an invasive plant in the eastern U.S., was planted in the 1940's as a living fence, for wildlife cover and to prevent soil erosion. However, R. multiflora rapidly spread from these original plantings via seeds and clonally, invading pasture and wooded areas. We …

Characterization of Polymorphic Microsatellites in Strawberry and Their Transferability to Other Genera in the Rosaceae Family
… and ten commercially important species in Rosaceae. Genetic diversity studies were carried among 16 diploid Fragaria accessions using these polymorphic microsatellites. The average number of alleles amplified for a polymorphic locus was 4.7 with maximum being 8.0 and minimum being 3.0. …

The chemistry of acacia gums
… in response to injury by trees belonging to the Rosaceae and Leguminosae families. Acacia trees belong to the Leguminosae family, and the exudate from a variety of acacia species is known as "gum arabic" or "gum acacia". Gum arabic is collected for industrial use from acacia trees grown in hot, …

The vascular flora and species distribution modeling of two rare species in Cloudland Canyon State Park, Dade and Walker Counties, Georgia
… Maxent for two rare species: Spiraea virginiana (Rosaceae), and Lilium philadelphicum (Lilliaceae). Surveys for the target species at the modeled sites were conducted in Cloudland Canyon State Park, resulting in no new occurrences of the species.

Improved regeneration and Agrobacterium-mediated transformation of wild strawberry (Fragaria vesca L.)
The Rosaceae contains many important commercially grown fruit crops. No comprehensive genomics platform is currently under development for fruit crops, giving functional genomics studies with wild strawberry (Fragaria vesca L.) the potential of identifying genes important in fruit crops. Fragaria …

Taxonomical use of floral scent data in apomictic taxa of Hieracium and Sorbus derived from hybridization
… in early as well as late branching families. Rosaceae and Asteraceae are particularly rich in apomictic taxa. In these families genera such as Hieracium and Sorbus contribute a lot to local species biodiversity in Central Europe because of their high number of apomictic species and taxa, which …

A biogeographic analysis of the species Fragaria vesca using microsatellite markers on a worldwide plant collection
… of research in the field of the Rosa (Rosaceae) plant family, the third most economically important of all plant families. Another importat reason for assessing the genetic population structure of the F. vesca is its vast distribution and the effect of climate change through the ages, …

Phenology and branching in eight selected species of the genus Cliffortia
… in the wind-pollinated genus Cliffortia (Rosaceae), has gone unnoticed. In this study stereo microscope examination and sketching of fresh and dried specimens, combined with extensive field observations, were performed on eight species of the genus. In its simplest form the inflorescence …
