Clarification of basal relationships in Rubus (Rosaceae) and the origin of Rubus chamaemorus
… 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 from this group and …

Genetic Diversity in Native and Invasive <i>Rubus </i>(Rosaceae)
… to predict 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 …

Flavour quality factors and its regulation in red raspberry (rubus idaeus)
Breeding in red raspberries is hampered by genetic incompatibility between varieties and a long juvenility period. Molecular breeding efforts in red raspberry have provided viable applications to incorporate disease resistance in new varieties. This approach could also be applied in developing …

Characterization of chalcone synthase genes in red raspberry cultivar (rubus idaeus)
… from the genome of the European red raspberries (Rubus idaeus) cv. Glen Moy (SCRI), using 454 sequencing technology assisted by a systematic construction of fosmid libraries. The two BACs (29M05 and 24B12) always presented similarities in almost analyses resulting from the presence of a 53 kb …

Regeneration and evaluation of first and second cycle somaclones of 'Thornless Evergreen' blackberry (Rubus laciniatus) Willd.)
… for 'Thornless Evergreen' (TE) blackberry (Rubus laciniatus Willd.) using thidiazuron (TDZ) and naphthaleneacetic acid. TDZ was superior to benzylaminopurine (BA) in promoting adventitious shoot formation on in vitro-grown TE leaves. TDZ was active at lower concentrations than BA and …

Stability of 'Thornless Evergreen' Blackberry in Vitro and Ex Vitro (Tissue Culture, Chimera, Variability, Somaclonal Variation, Rubus)
'Thornless Evergreen', Rubus laciniatus Willd. (2n = 4x = 28), is a periclinal chimeral blackberry in which a mutated thornless epidermis surrounds a core of cells with a thorny genotype. Adventitious shoots from roots are always thorny, and gametes carry the thorny gene. Via micropropagation, pure …

Linkage mapping in tetraploid blackberry (Rubus spp.) using high-throughput genomic sequencing and restriction-site associated DNA sequencing (RAD-seq)
… mapping in cultivated polyploid species of Rubus, in particular blackberry, has lagged behind diploid members of the genus due to the complex analyses required to deduce allele dosage among homologous and homeologous chromosomes. Traditional techniques for studying linkage in tetraploid …
