Nitric oxide and calcium are two kinds of signaling molecules that are the key secondary messenger. An experiment was conducted in saline culture solution to examine the cross-talk interactions of nitric oxide and calcium in common wheat under NaCl stress. Addition of 100 mM NaCl reduced plant growth, decreased the chlorophyll content and root activity,(More)
A greenhouse hydroponic experiment was performed to evaluate how peanut seedlings (Arachis hypogaea L.) responded to iron (Fe) deficiency stress in the presence of sodium nitroprusside (SNP), a nitric oxide (NO) donor. The results showed that Fe deficiency inhibited peanut plant growth, decreased chlorophyll and active Fe concentrations, and dramatically(More)
Iron (Fe) deficiency chlorosis is a common and severe nutritional deficiency in plants, and nitric oxide (NO) is an important signaling molecule in regulating Fe homeostasis in plants. We studied the effect of sodium nitroprusside (SNP, an NO donor) on Fe uptake, translocation, storage, and activation in a greenhouse. The concentrations of active Fe, total(More)
In isolated rabbit heart perfused with hemoglobin-free Tyrode's solution at 28 degrees C the response time of myocardial oxidative phosphorylation to steps in heart rate, which is about 8 s, is decreased by about 2.5 s when lactate of pyruvate are given as exogenous carbon substrate. A hypothesis that may explain the decrease in response times is that(More)
