Vacuoles isolated by a mechanical slicing method from developing tubers of Jerusalem artichoke (Helianthus tuberosus L.) contain activities of the two principal enzymes responsible for fructan synthesis: sucrose-sucrose fructosyl transferase and fructan-fructan fructosyl transferase. Both enzymes are associated with the vacuolar sap and not with the tonoplast. In vacuoles isolated from dormant ...

Italy represents the world leading producer of globe artichoke, and Puglia (Southern Italy) supplies about one-third nation’s production. In this research, influence mulching (both living mulch with subterranean clover biodegradable film) on both weed infestation artichoke yield in comparison conventional tillage was evaluated. Two genotypes (Capriccio—hybrid cultivar—and Brindisino—sanitized l...

a total of 240, one-day-old quail chicks (coturnix coturnix japonica) were used to study the effects of artichoke leaf meal (alm) and vitamin e in diet on growth performance, ileal microbial populations and intestinal morphology in a 42-d trial. this experiment was performed as a completely randomized design with 4 replicates of 15 quails each, using a 4 × 2 factorial arrangement with diet and ...

Galactinol synthase (GS, UDP-alpha-d-galactose:1l-myo-inositol-1-O- alpha-d-galactopyranosyltransferase) is a key enzyme in the biosynthetic pathway of the raffinose family of oligosaccharides. The subcellular location of GS was studied in the parenchyma of stachyose-storing tubers of Japanese artichoke (Stachys sieboldii) by isolation of protoplasts and vacuoles. A comparison of the activities...

The biosynthetic enzymes DNA polymerase, thymidine kinase (TdR kinase) and thymidine monophosphate kinase (dTMP kinase) show characteristic patterns of activity associated with cell division in synchronously dividing tissue cultures of the Jerusalem artichoke. In each case the first major increase in enzyme activity is coincident with and dependent upon DNA replication. In addition the increase...

Inulin is a labile polyfructose polymer found in many sources as chicory, artichoke and dahlia roots. It ́s derived FOS (Fructo-OligoSaccharides) are produced using endo-inulinases or alternatively with less expensive and safe catalysts such as phosphoric and citric acids with good yields. Inulin and FOS deserve an important role against some diseases as colon cancer because can be selectively f...
