Preservation Methods for Jerusalem Artichoke Cultivars
Preservation methods were evaluated forjerusalem artichokes (Helianthus tuberosus L.) to facilitate the back-up of field collections. In vitro plant cultures were established from field-harvested tubers for nine jerusalem artichoke cultivars obtained from the Plant Gene Resources of Canada, Saskatoon Research Center, Saskatoon, Canada. Most cultivars could be maintained at 5 °C or under 25°C gr...
متن کاملEngineering herbicide metabolism in tobacco and Arabidopsis with CYP76B1, a cytochrome P450 enzyme from Jerusalem artichoke.
The Jerusalem artichoke (Helianthus tuberosus) xenobiotic inducible cytochrome P450, CYP76B1, catalyzes rapid oxidative dealkylation of various phenylurea herbicides to yield nonphytotoxic metabolites. We have found that increased herbicide metabolism and tolerance can be achieved by ectopic constitutive expression of CYP76B1 in tobacco (Nicotiana tabacum) and Arabidopsis. Transformation with C...
متن کاملRegulation of phosphoenolpyruvate metabolism in mitochondria from guinea pig liver.
Previous studies by us have shown that respiring guinea pig liver mitochondria can synthesize P-enolpyruvate from a variety of ordinarily available carbon intermediates. In this study, dinitrophenol was found to reduce substantially Penolpyruvate formation owing to a deficiency of intramitochondrial ATP, and this reduction could not be relieved by stimultaneous substrate level phosphorylation o...
متن کاملTissue Fractions of Cadmium in Two Hyperaccumulating Jerusalem Artichoke Genotypes
In order to investigate the mechanisms in two Jerusalem artichoke (Helianthus tuberosus L.) genotypes that hyperaccumulate Cd, a sand-culture experiment was carried out to characterize fractionation of Cd in tissue of Cd-hyperaccumulating genotypes NY2 and NY5. The sequential extractants were: 80% v/v ethanol (FE), deionized water (FW), 1 M NaCl (FNaCl), 2% v/v acetic acid (FAcet), and 0.6 M HC...
متن کاملRibonucleic acid polymerase activities in Jerusalem artichoke tissue.
1. Artichoke tuber tissue contained RNA polymerase activity bound to the chromatin and in the supernatant after chromatin sedimentation. 2. The activity in the supernatant, the soluble polymerase, was fractionated into polymerases I and II by DEAE-cellulose chromatography, and the properties of each activity were determined. 3. The proportions of chromatin-bound and soluble activities varied wi...
