The regulation of nitrate and ammonium transport systems in plants.
Inorganic nitrogen concentrations in soil solutions vary across several orders of magnitude among different soils and as a result of seasonal changes. In order to respond to this heterogeneity, plants have evolved mechanisms to regulate and influx. In addition, efflux analysis using (13)N has revealed that there is a co-ordinated regulation of all component fluxes within the root, including bio...
متن کاملPlant preference for ammonium versus nitrate: a neglected determinant of ecosystem functioning?
Although nitrogen (N) availability is a major determinant of ecosystem properties, little is known about the ecological importance of plants' preference for ammonium versus nitrate (β) for ecosystem functioning and the structure of communities. We modeled this preference for two contrasting ecosystems and showed that β significantly affects ecosystem properties such as biomass, productivity, an...
متن کاملEvaluation of natural zeolite clinoptilolite efficiency for the removal of ammonium and nitrate from aquatic solutions
Background: Surface water and groundwater pollution with various forms of nitrogen such as ammonium and nitrate ions is one of the main environmental risks. The major objectives of this study were to evaluate the capacity of natural zeolite (clinoptilolite) to remove NO3- and NH4+ from polluted water under both batch and column conditions. Methods: The laboratory batch and column experiments we...
متن کاملInvestigating Consumer Preference for Organic, Local, or Sustainable Plants
Organically and locally grown food products have become increasingly popular in recent years. However, unlike food products, consumers purchase most outdoor plants for their aesthetic value rather than their nutritional value. Many of the health concerns related to food products might not be applicable to ornamental plants, so the demand for organic non-food plants is unknown. Using a survey wi...
