How nitrate regulates gene expression in legumes

Plants in the bean family (legumes) form nodules on their roots to take up nitrogen. Legumes will stop nodule production when nitrogen is plentiful (Figure 1), but precisely how nitrate presence controls nodule formation ...

The blast that shook the ionosphere

Just after 6 p.m. local time (15.00 UTC) on August 4, 2020, more than 2,750 tons worth of unsafely stored ammonium nitrate exploded in Lebanon's port city of Beirut, killing around 200 people, making more than 300,000 temporarily ...

Technology to detect chemicals in fruit and vegetables

An ITMO Ph.D. student with her colleagues from Russia, Spain and Singapore has developed flexible sensing films based on silver nanoparticles that can be used to identify the presence of pesticide residue on the surface of ...

The dynamics of nitrogen-based fertilizers in the root zone

Nutrient contamination of groundwater as a result of nitrogen-based fertilizers 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 ...

From nitrate crisis to phosphate crisis?

The aim of the EU Nitrates Directive is to reduce nitrates leaking into the environment in order to prevent pollution of water supplies. The widely accepted view is that this will also help protect threatened plant species ...

Research teams make plant nutrient delivery breakthrough

When most people think of fungi, the thoughts are usually not good, turning to something that does damage more than those that are actually helpful. Yet, fungi play a critical role in the growth and development of plant life ...
