avena/hypoxia

The comparative effects of metabolic inhibitors on acid- and auxininduced growth in oat (Avena sativa L. var. Victory) coleoptile segments have been examined. Acid (pH 4)-induced growth in both peeled and unpeeled segments is inhibited by 1 millimolar KCN when added at the time of acidification. KCN

Physiological and metabolic responses to anoxia were compared for aerobically germinated seedlings of barley (Hordeum vulgare), oat (Avena sativa) and rice (Oryza sativa). Coleoptile growth of barley, oat and rice seedlings was suppressed by a 24 h-anoxic stress, but the growth of the rice

Short, high intensity pulses of red and far red light are used to study, at room temperature, the kinetics of the in vivo dark reaction responsible for irradiation-enhanced phytochrome pelletability. The t((1/2)) for this reaction is 2 seconds at 25 C in both Avena shoots and Zea mays coleoptiles.

The ability to avoid the ethanol-induced injury was evaluated in rice (Oryza sativa L.) and oat (Avena sativa L.) coleoptiles. The growth of the rice and oat coleoptiles was inhibited by ethanol exogenously applied at concentrations greater than 200 and 30 mM, respectively. At 300 mM ethanol, oat

OBJECTIVE CaCo-2 colon cancer cells and HepG2 liver cancer cells represent two malignant cell lines, which show a high resistance to apoptosis induced by the conventional anticancer drugs. Vitexin-2-O-xyloside (XVX) and avenanthramides (AVNs) are naturally occurring dietary agents from Beta vulgaris

1. A further study has been made of the effect of indole-3-acetic acid (auxin) on protoplasmic streaming in the epidermal cells of the Avena coleoptile. 2. The transient nature of the effect of auxin, both in accelerating and retarding streaming, is due to the temporary exhaustion of carbohydrate

In Avena coleoptile segments a decrease of cytoplasmic pH activates energy-dependent H(+) extrusion into the apoplast, thereby triggering extension growth. This sequence of events cannot be inhibited by cycloheximide and is induced by the following conditions and compounds. (i) A short anaerobic
