An attempt was made to identify the role of peroxidase activity as well as the changes of peroxidase (POX) isozymes that control adventitious root formation at the base of hypocotyl cuttings of mung bean (Vigna radiata L. cv. 105). Three phases of the adventitious root formation process were identified; induction (0-24 h), initiation (24-72 h) and expression (after 72 h). The lower peroxidase a...

Safflower ( Carthamus tinctorius L.) is currently being developed as a platform for the production of novel proteins. Methods for detecting and quantifying transgenic safflower are needed to ensure seed quality and to monitor for its adventitious presence. We developed and compared three methods of assaying for transgenic safflower presence in conventional seedlots: field bioassays, enzyme-link...

Withanolides are a group of naturally occurring steroidal lactones present in roots and leaves of Withania somnifera (L.) Dunal. Withanolides possesses a wide range of pharmacological activities including anticancer to treat various neurodegenerative disorders such as Alzheimer’s, Parkinson’s and Huntington’s diseases. In recent years, several pharmacological studies have been conducted to util...

Relatively high percentages of adventitious shoot regeneration have consistently been obtained from leaves of some apricot cultivars. For the cultivar 'Helena', explants from the proliferation medium were more reactive than those from the elongation medium. The best results were obtained with thidiazuron (TDZ). When 6-benzylamino-purine (BAP) was used instead of TDZ, the regeneration percentage...

BACKGROUND The European Respiratory Society (ERS) lung sounds repository contains 20 audiovisual recordings of children and adults. The present study aimed at determining the interobserver variation in the classification of sounds into detailed and broader categories of crackles and wheezes. METHODS Recordings from 10 children and 10 adults were classified into 10 predefined sounds by 12 obse...

Studies were conducted in early 2003 to determine the effect of root source and length on yield of adventitious shoots and plant yield from root cuttings of Arkansas-developed thornless blackberries. In the first study, roots from ‘Arapaho’ and ‘Apache’ plants grown in an aboveground bed containing commercial potting soil were compared to field-grown roots. Bed-grown roots averaged 6.9 shoots p...
