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.....»»
Chemical chameleon reveals novel pathway for separating rare-earth metals
Researchers at the Department of Energy's Oak Ridge National Laboratory have found a chemical "chameleon" that could improve the process used to purify rare-earth metals used in clean energy, medical and national security applications......»»
Research team achieves high-resolution 2D imaging for graphene devices under high pressure
A research team led by Prof Zhang Zengming from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) has combined nitrogen-vacancy (NV) centers in diamond with a diamond anvil cell (DAC) to achieve non-inv.....»»

From wild relatives to super tomatoes: Unearthing new genetic potential
Tomato breeding has historically depended on a narrow genetic pool, leading to decreased diversity and loss of valuable traits. Traditional methods and biparental populations fall short in harnessing the full potential of wild relatives, posing chall.....»»
Twenty-six states may soon need to regulate cannabis—here"s what they can learn from Colorado and Washington
The U.S. Drug Enforcement Administration has made moves to reclassify marijuana, making it a type of legal but regulated medicine, like Tylenol with codeine or some steroids......»»
Cells use alternative splicing to regulate gene expression, research suggests
Alternative splicing is a genetic process where different segments of genes are removed, and the remaining pieces are joined together during transcription to messenger RNA (mRNA). This mechanism increases the diversity of proteins that can be generat.....»»
Chemists achieve PFAS-free synthesis of fluorinated pharmaceutical and agrochemical compounds
Chemists at the University of Amsterdam have developed a method to furnish a range of molecules with a trifluoromethyl group attached to a sulfur, nitrogen or oxygen atom. Their procedure, which is published in Science, avoids the use of PFAS reagent.....»»
Drowning tomatoes for science
I can barely hear Esther Ngumbi over the roar of greenhouse fans as she shows me around her rooftop laboratory in Morrill Hall. The benches are full of tomato plants, and the tomatoes don't look good. Half of the plants are submerged in bins of water.....»»
A chloroplast-mimicking nanoreactor for enhanced CO₂ electrocatalysis
Chloroplast, which is a double-membrane-bounded organelle, is the main site for CO2 fixation via photosynthesis in green plants. The double-membrane configuration can regulate the transport of substances into and out of the chloroplasts with the aid.....»»
Study shows pollution affects the growth and behavior of aquatic organisms
Research at the University of Jyväskylä, Finland, reveals that size-based selection, as happens in fishing, may impact the stress tolerance of fish, which in turn has a significant impact on the condition and coping of fish in changing environments.....»»
Study finds flexibility and helical twists of actin filaments regulate actin-binding proteins
Researchers at Kanazawa University have published an article in eLife deciphering the actin structure-dependent preferential cooperative binding of cofilin......»»
Moths may use disco gene to regulate day/night cycles
How does one species become two? If you're a biologist, that's a loaded question. The consensus is that, in most cases, the process of speciation occurs when individuals from a single population become geographically isolated. If they remain separate.....»»
Tomato ripening study highlights cell wall component interactions
Tomato fruit ripening involves intricate biochemical and structural changes, particularly within the cell wall, which are vital for the fruit's final texture and quality. These changes include modifications in polysaccharides and proteins, but the sp.....»»
New genetic sensor for DNA methylation discovered
DNA methylation is a process in which a methyl group is attached to the cytosine base of the DNA molecule, and is a major way that DNA is epigenetically marked. Epigenetic modifications can act as on–off switches to regulate gene expression and hel.....»»
Novel silica nonwoven fabric scaffold enhances understanding of cell-to-cell interactions
Communication and coordination among different cells are fundamental aspects that regulate many functions in our body. This process, known as paracrine signaling, involves the release of signaling molecules by a cell into its extracellular matrix (EC.....»»
Nitrogen deposition also reduces biodiversity on a larger scale, research shows
It has long been known that nitrogen deposition, where nitrogen is released from the atmosphere into soil or water, can lead to biodiversity loss on a small scale. New research shows that this effect can also be seen in larger areas of several kilome.....»»
The pioneering sugarcane variety transforming China"s sugar industry
A research team at the Liucheng Sugarcane Research Units (LC-SRU) developed the fifth-generation sugarcane variety LC05-136, which has become a flagship in China due to its high yield, high sugar content, and strong tolerance to drought and cold stre.....»»
Tree mortality may lead to carbon tipping point in the Amazon by 2050s
The Amazon rainforest is home to a diverse cast of plants and animals. This vital, verdant landscape also plays a crucial role in managing the effects of climate change by storing significant amounts of carbon and helping regulate temperatures and ra.....»»
Newly discovered ability of comammox bacteria could help reduce nitrous oxide emissions in agriculture
An international research team led by the Centre for Microbiology and Environmental Systems Science (CeMESS) at the University of Vienna has discovered that comammox bacteria, first identified by them in 2015, can grow using guanidine, a nitrogen-ric.....»»
Developing a simple, cost-effective method to identify the targets of a crucial protein-modifying enzyme
