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 in these plants has been a my.....»»
Electrified membranes with carbon nanotubes offer faster nitrate removal in drinking water
Nitrate contamination in water has long presented threats to the environment and human health. Now, Yale researchers have developed an efficient and effective way to remove it......»»
Rhythmic gene expression in plants is crucial for symbiosis with nutrient-providing bacteria, study finds
Legumes thrive in low-nitrogen environments by partnering with rhizobia, soil bacteria that convert atmospheric nitrogen into ammonium, a usable form for the plants. These beneficial bacteria are housed in root nodules formed on legume roots......»»
Study reveals key gene protecting plants from harmful metals in soil
The negative impact of human activity on Earth doesn't just affect our planet's atmosphere—it goes much deeper, into its soils. For instance, excessive application of manure or sewage sludge can increase heavy metal concentrations in agricultural l.....»»
Nature"s gender reveal: Key gene controls female flowers in Cucurbita pepo
Sex determination in cucurbits such as squash is influenced by a complex interplay of environmental, hormonal, and genetic factors, with ethylene being the primary hormone promoting female flower development......»»
From roots to leaves: The nitrogen connection to photosynthetic efficiency
Photosynthesis efficiency in plants is influenced by the type of nitrogen absorbed. Ammonium (NH4+) and nitrate (NO3-) are the primary nitrogen sources, each affecting plant physiology differently. Variations in leaf anatomy, such as cell wall thickn.....»»
Gene silencing tool has a need for speed: Research provides deeper insight into RNAi tool design
RNA interference (RNAi) is a process that many organisms, including humans, use to decrease the activity of target RNAs in cells by triggering their degradation or slicing them in half. If the target is a messenger RNA, the intermediary between gene.....»»
