How does the autophagic pathway regulate low-nitrogen tolerance in tomato?
Nitrogen (N) deficiency first affects the N uptake and assimilation systems of plants. Nitrate, the main source of plant N, is absorbed and transported by nitrate transporters. Nitrate can be metabolized directly in the roots after absorption and sto.....»»
New research opens avenues for more efficient and stable blue OLED displays
New research from scientists at Durham University reveals an unexpected pathway toward brighter, more efficient, and more stable blue organic light-emitting diodes (OLEDs)......»»
Researchers uncover a key link in legume plant-bacteria symbiosis
Legume plants have the unique ability to interact with nitrogen-fixing bacteria in the soil, known as rhizobia. Legumes and rhizobia engage in symbiotic relations upon nitrogen starvation, allowing the plant to thrive without the need for externally.....»»
Small adjustments can reduce nitrogen loss in peat meadows, says researcher
Relatively simple adjustments can reduce nitrogen losses on dairy farms in peatland areas. That's the conclusion of the Ph.D. research by Leiden environmental scientist Jeroen Pijlman at the Louis Bolk Institute. Protein-poor grass species and narrow.....»»
Secrets of soil-enriching pulses could transform future of sustainable agriculture
From lentils to chickpeas, and even the humble baked bean, pulses are perhaps best known as an alternative, plant-based source of protein. These plants are environmental heroes: they work together with soil microbes to "fix" nitrogen from the air, en.....»»
Female mosquitoes found to regulate their own population density at breeding sites using communal cues
When female mosquitoes feed, they don't seem to mind a crowd because lots of carbon dioxide usually means there's food. They were thought to be more solitary, however, when laying eggs. New research has revealed quite the opposite for the deadly Aede.....»»
Trees can make farms more sustainable—here"s how to help farmers plant more
Imagine making one change to a farm field so that as well as producing food, it also generated building materials, fuel and fodder. At the same time, this change would nourish the health of the soil, regulate the micro-climate and support pest-contro.....»»
Natural gas flare samples collected by aircraft reveal high variation in nitrogen oxides emission estimates
Natural gas flaring, or burning, is commonly used in parts of the United States to dispose of the gas byproduct from oil extraction. The flare's combustion converts hydrocarbons to carbon dioxide and water, which lessens the climate impact and reduce.....»»
Effects of nitrogen and phosphorus additions on soil nematode community of soybean farmland
As a predator of soil microorganisms, nematodes respond rapidly to changes in soil environment, which can reflect climate conditions, ecosystem succession status, nutrient cycling and soil ecosystem health. In agroecosystems, nitrogen and phosphate f.....»»
Guanine synthesis yields new insights into nitrogen"s role in nanocarbon catalysis
Recently, carbon-based catalysts—especially nitrogen-doped nanocarbons—have emerged as sustainable, reliable alternatives to the metal catalysts traditionally used to support chemical reactions......»»
Unveiling biosynthesis of hyperoside: A pathway to sustainable production in Hypericum monogynum
Hyperoside, a beneficial flavonoid galactoside found in both medicinal and edible plants, plays a critical role in plant growth, self-defense, and breeding, as well as in human health through its numerous pharmacological properties. However, the bios.....»»
Team observes third-order exceptional line in nitrogen-vacancy spin system
Researchers have systematically studied the relations between symmetries and high-order non-Hermitian exceptional points (EPs), and observed the third-order exceptional line (EL) in a nitrogen-vacancy (NV) spin system. The work is published in the jo.....»»
Shedding light on shadows: Unveiling the impact of low light on tomato disease susceptibility and defense mechanisms
The global challenge of plant disease outbreaks under low light intensities leads to significant crop yield losses, with the mechanisms of low light's impact on plant defense poorly understood. Research has identified high light conditions as enhanci.....»»
Grape white rot resistance and the role of VvWRKY5 in enhancing pathogen defense through the jasmonic acid pathway
Grape white rot, caused by Coniella diplodiella (Speg.) Sacc. (Cd), significantly impacts grape production and quality, highlighting the need for effective disease management strategies beyond fungicide use due to concerns over food safety and enviro.....»»
Research reveals minerals in soil shield microbial remains to aid carbon storage
A new study by Chinese researchers has revealed that soil minerals play a critical role in protecting the remains of dead microbes, thereby promoting carbon and nitrogen storage in the soil......»»
Study finds high nitrogen fertilizer input enhances the microbial network complexity in paddy soil
In paddy field, flood-and-drain cycles produce variations in reduced and oxidized environments, which are appropriate habitats for a wide variety of microorganisms. Nitrogen (N) fertilization drives the structure and function of soil microbial commun.....»»
Researchers realize photo-driven nitrogen fixation and ammonia synthesis mediated by lithium hydride
Ammonia is essential for food and future energy supply. In the industry, it is mainly produced by the Haber-Bosch process, which operates at high temperatures and pressures. Due to the high energy consumption and carbon emissions of ammonia industry,.....»»
Transcription factor"s key role in grafted cucumbers reveals salt tolerance in crops
Soil salinity, impacting about 1 billion square hectometers worldwide, significantly hinders crop growth. Plants counteract this through signaling pathways involving molecules such as H2O2 and ABA. NAC transcription factors, which are unique to plant.....»»
LSH genes associated with defining the shapes of stems, flowers and leaves required for N-fixing root nodules
Cambridge scientists have identified two crucial genetic factors needed to produce specialized root organs that can accommodate nitrogen-fixing bacteria in legumes such as peas and beans......»»
Microbial research unravels a global nitrogen mystery
Novel research led by Wei Qin, an assistant professor of microbiology at the University of Oklahoma, that significantly changes the understanding of ammonia oxidation, a critical component of the global nitrogen cycle, has been published in the journ.....»»
Nitrogen-based fertilizers differentially affect protist community composition in paddy field soils, finds study
The soil microbiome has far-reaching significance, particularly for rice production, which can be better explained with a Japanese proverb: "Rice grows with soil fertility, while upland crops depend on fertilization." Therefore, understanding the pad.....»»
