Regeneration and evaluation of first and second cycle somaclones of 'Thornless Evergreen' blackberry (Rubus laciniatus) Willd.)
… was developed 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 …

Stability of 'Thornless Evergreen' Blackberry in Vitro and Ex Vitro (Tissue Culture, Chimera, Variability, Somaclonal Variation, Rubus)
… 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 thornless plants were selected from …

Effect of Harvest Time on the Incidence of Red Drupelet Reversion and Development of Tetraploid Linkage Maps in Blackberry
<p>The cultivated eastern U.S. blackberry (Rubus L. subgenus Rubus Watson) has gone through tremendous strides in both trait improvement and market outreach at the University of Arkansas System Division of Agriculture (UA System). What began as primarily a pick-your-own local fruit found mostly in …

Linkage mapping in tetraploid blackberry (Rubus spp.) using high-throughput genomic sequencing and restriction-site associated DNA sequencing (RAD-seq)
… 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 species, including Rubus, …

Digestion and Chelonochory in Two Sympatric Species of Box Turtles, Terrapene Carolina and Terrapene Ornata, on Pure Diets of Fruit
… seeds from three different pure diets of fuit (blackberry, mayapple, and commercial strawberry). Blackberry was considered familiar to both species, mayapple considered familiar to T. carolina, and strawberry unfamiliar to both species. Fruit diet had a significant effect on digestive efficiency …

Characterising the techno- and bio-functional properties of milk protein-polyphenol complexes for application in performance nutrition
… When milk protein systems contained blackberry polyphenols, their heat stability increased in the pH range 6.2-6.4. In this pH range, blackberry polyphenols bound calcium, which prevented protein aggregation and increased heat stability. Co-concentration of milk proteins and …
