Nitrogen foraging ability of plants relies on mobile shoot-root hormone signal
Nagoya University researchers discovered the molecular mechanisms underlying the shoot-to-root stage of nitrogen-demand signaling in plants. The team found that genes encoding CEPD polypeptides are switched on in the shoots in response to nitrogen starvation in the roots. These polypeptides then descend into the roots, and activate a nitrate transporter gene only if sufficient nitrate is available in the surrounding soil. These findings have implications for maximizing plant nutrient acquisition and improving agricultural productivity. (2017-03-27)

Team discovers a significant role for nitrate in the Arctic landscape
Because of the very low nitrate levels found in arctic tundra soil, scientists had assumed that plants in this biome do not use nitrate. But a new study co-authored by four Marine Biological Laboratory (MBL) Ecosystems Center scientists challenges this notion. The study has important implications for predicting which arctic plant species will dominate as the climate warms, as well as how much carbon tundra ecosystems can store. (2018-03-23)

A scientist at the Hebrew University of Jerusalem has discovered a way to literally catch terrorists red-handed. A new chemical spray detector developed by Professor Joseph Almog of the Hebrew University's Casali Institute of Applied Chemistry detects the homemade explosive urea nitrate. When sprayed on cotton swabs taken from the hands of a suspect, if they have had recent contact with urea nitrate, the chemical will turn a blood red hue. (2007-10-31)

Study sheds light on how plants get their nitrogen fix
Legumes are widely-consumed plants that use soil bacteria to obtain nitrogen through root nodulation. The process is energetically costly, and so legumes inhibit nodulation when soil nitrate is available. However, the mechanism that drives this inhibition is unknown. Researchers at the University of Tsukuba found that NRSYM1 is responsible for inhibiting nodulation in the presence of nitrate, and acts by directly regulating gene expression. The findings may aid agricultural efforts to improve the crop efficiency of legumes. (2018-02-16)

Dynamics in the root zone
Nutrient contamination of groundwater as a result of nitrogen-based fertilisers is a problem in many places in Europe. Calculations by a team of scientists led by the UFZ have shown that over a period of at least four months per year, nitrate can leach into the groundwater and surface water on about three-quarters of Europe's agricultural land. The proportion of areas at risk from nitrate leaching is thus almost twice as large as previously assumed. (2020-12-09)

The first nationwide investigation of potential socioeconomic disparities in nitrate concentrations in US drinking water is reported in the open access journal Environmental Health. The authors, from Silent Spring Institute, USA, note that understanding the extent of current exposures -- particularly among vulnerable communities -- is critical for developing effective strategies to reduce exposure. (2019-01-16)

New water-quality data on impact of corn, soybeans on nitrate in Iowa streams
As Iowa farmers have planted more acres of corn to meet the demand driven by the corn-based ethanol industry, many models predicted that nitrate concentrations in Iowa streams would increase accordingly. However, recent University of Iowa research based on water monitoring and published in the Journal of Soil and Water Conservation casts doubt on these predictions. (2016-05-24)

Learning from nature, scientists from the Center for Sustainable Resource Science in Japan and the Korean Basic Science Institute (KBSI) have found a catalyst that efficiently transforms nitrate into nitrite -- an environmentally important reaction -- without requiring high temperature or acidity, and now have identified the mechanism that makes this efficiency possible. (2020-04-02)

Explosion in Tianjin Port enhanced atmospheric nitrogen deposition over the Bohai Sea
In August 2015, a serious explosion occurred in Tianjin Port, leaving at least 50 dead and hundreds injured. Fire and smoke soared into the skies of Tianjin. A large amount of nitrogen-containing pollutants generated by the explosion were transmitted to the Bohai Sea. The impact area of the explosion on the Bohai Sea is about 1/5 of the total area of the Bohai Sea (2019-11-13)

Illinois River water quality improvement linked to more efficient corn production
In a new University of Illinois study, nitrate concentrations and loads in the Illinois River from 1983 to 2014 were correlated with agricultural nitrogen use efficiency and nitrate discharged from Chicago's treated wastewater. The amount of nitrate that flowed down the river each year from 2010 to 2014 was 10 percent less than the average amount during a baseline period of 1980 to 1996. This reduction is a positive step toward the ultimate goal to reduce nitrate concentrations by 45 percent. (2016-05-10)
