Mitochondrial biogenesis was induced in Jerusalem artichoke (Helianthus tuberosus) tuber by aging tissue discs in distilled water for up to 26 hours. Changes in the purified mitochondrial fraction during aging included an increase in both protein content and specific respiratory activity. Using intact isolated mitochondria, conditions were optimized for incorporation of radioactive amino acid i...

Spin labeling studies using mitochondrial membranes of Jerusalem artichoke (Helianthus tuberosus L.) showed that the decrease during winter in the temperatures of the upper and lower lipid transitions correlated with the development of freezing hardiness of the tubers. The killing temperature for tuber tissue reached a minimum of -12 C, about 5 C degrees lower than the lower transition. Freeze-...

Diabetes is caused by excessive accumulation of glucose in human blood. The disease is hereditary, but can also be affected by the environment. At present, there are many limitations in the development of single-target drug therapy for the treatment of diabetes. Chinese herbal medicine has long been used for diabetes treatment as well as many other diseases in East Asia. Clinical practice has d...

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...
