Nutrient Signaling by Nitrate and Calcium.
An especially intriguing aspect of nutrients is their capacity to serve as signals. Nutrient signaling pathways play key roles in plant growth and development and can interact and overlap in interesting ways. In this issue, Riveras et al. (2015) report on two plant macronutrients, nitrate and calcium, and show how responses induced by nitrate depend in part on calcium signaling mechanisms. The ...
متن کاملNitrate Reductase Activity in Corn Seedlings as Affected by Light and Nitrate Content of Nutrient Media.
The requirement of light for the reduction of nitrate by higher plants has been under investigation for sonme time. Burstronm (2) obtained evidence that wheat leaves would reduce nitrate in the light but not in the dark. He concluded that nitrate reduction was directly linked to a photochemical reaction, or that it occurred concomitantly with the fixation and reduction of carbon dioxide. In con...
متن کاملNitrate: nutrient and signal for plant growth.
The mineral nutrient needed in greatest abundance by plants is nitrogen. Plants, however, must compete for nitrogen in the soil with abiotic and biotic processes such as erosion, leaching, and microbial consumption. Soil nitrogen is also lost when crops are harvested and plant material is removed from the soil. To be competitive, plants have evolved several mechanisms to acquire nitrogen at low...
متن کاملEvaluating Foliar Application of Calcium Nitrate, Calcium Chloride and Boric Acid on Physiological Disorders of ‘Kaleh - Ghoochi’ Pistachio
Pistachio suffers from some physiological disorders such as fruit abscission, endocarp lesion, blankness, non-split, early-split and deformed nuts. In this experiment, the effects of calcium nitrate (2 gr/lit), calcium chloride (2 gr/lit), boric acid (200 ppm) and their combination treatments were investigated on physiological disorders of ‘Kaleh-Ghoochi’ pistachio. Foliar application was appli...
متن کاملDietary nitrate and blood pressure: evolution of a new nutrient?
Dietary nitrate is mainly obtained from vegetables, especially green leafy vegetables and beetroot. As a result of early research, dietary nitrate is currently viewed as a contaminant linked to increased risks of stomach cancer and methaemoglobinaemia. Consequently, nitrate levels are restricted in certain vegetables and in water supplies to ensure exposure levels remain below an acceptable dai...
