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.....»»
Has Pakistan begun the crackdown on "unregistered" VPNs?
Throttled VPNs returned working as usual by Sunday night, but Pakistan's plan to regulate VPN usage is just started. Here's all you need to know......»»
Smart surveillance system improves tomato plant monitoring with high-speed disease detection, fruit counting
Tomatoes are a critical source of nutrients and remain one of the most widely cultivated fruits globally. However, intensive greenhouse practices increase susceptibility to diseases, which can reduce yields by up to 30% and degrade fruit quality......»»
Heat hardiness: Scientists identify key phase for tomato heat tolerance
By studying tomato varieties that produce fruit in exceptionally hot growing seasons, biologists at Brown University identified the growth cycle phase when tomatoes are most vulnerable to extreme heat, as well as the molecular mechanisms that make th.....»»
Scientists reveal strigolactone perception mechanism and role in tillering responses to nitrogen
"How is plant growth controlled?" and "What is the basis of variation in stress tolerance in plants?" were among the 125 most challenging scientific questions, according to the journal Science in 2016......»»
New research may lead to potatoes that are less reliant on nitrogen fertilizers
Because nitrogen fertilizers contribute to global greenhouse gas emissions, scientists are looking for ways to modify agricultural plants so that they rely on less nitrogen. In research published in New Phytologist, investigators have found that bloc.....»»
New survey finds alarming tolerance for attacks on the press in US, particularly among white, Republican men
Press freedom is a pillar of American democracy. But political attacks on US-based journalists and news organizations pose an unprecedented threat to their safety and the integrity of information......»»
Researchers uncover focal adhesions as subcellular signaling hubs in PI3K-AKT pathway
The phosphatidylinositol 3-kinase (PI3K)-AKT signaling pathway is one of the most critical and extensively investigated signaling pathways. It is the central regulator of various cellular processes including cell growth, proliferation, metabolism, an.....»»
International team discovers small molecules that regulate how fast plant leaves age
Two small molecules that are produced by the plant Arabidopsis thaliana are shown to have the opposite effect on how fast its leaves age. The molecules are peptides, short chains of amino acids. While the peptide SCOOP10 accelerates aging, SCOOP12 su.....»»
Are bioplastics really the wonder alternative to petro plastics?
Alternatives to petrochemical-based plastics are emerging, made from everything from banana leaves to tomato skins, especially for food packaging......»»
Pivotal gene found to confer heat tolerance in perennial ryegrass
Perennial ryegrass (Lolium perenne L.), widely cultivated in the cool-season for forage supply and turfgrass, is extremely susceptible to high temperatures. A recent study has discovered a pivotal stress-responsive gene, combating heat stress in pere.....»»
Glycans can regulate their own biosynthesis by modifying enzyme activity
Glycans are chains of sugars that attach to cells through proteins or lipids, changing their chemical characteristics. Glycans can be incredibly complex and branched in structure, contributing to the stability of the extracellular domain of cells and.....»»
Bacterial pathogen must balance between colonizing airways and developing antibiotic tolerance, study reveals
Imagine trying to settle into a new home while constantly being attacked. That's what the bacterium Pseudomonas aeruginosa faces when it infects the lungs, and it can't both spread and protect itself from antibiotics at the same time......»»
Column: Industry may need to think about Musk-Trump relations
We don't know why Elon Musk has become Donald Trump's biggest supporter, but he could be looking to regulate the regulators......»»
New chemical treatment reduces number of plant pores that regulate water loss
Researchers from Nagoya University Institute of Transformative Biomolecules (WPI-ITbM) in Japan and their colleagues have identified and derivatized a chemical compound that effectively regulates the density of stomata in model plants. Stomata are cr.....»»
Oriental hornets do not get sick or die when consuming very large amounts of alcohol, study shows
A team of behavioral ecologists, zoologists and crop protection specialists from Tel Aviv University reports that Oriental hornets have the highest-known tolerance to alcohol in the animal kingdom. In their study published in Proceedings of the Natio.....»»
Nitrogen-fixing plant diversity declines with over-fertilization, study finds
Anthropogenic nitrogen deposition and climate change can reduce the competitive advantage of nitrogen-fixing plants, leading to reduced diversity of these plants in a community. Surprisingly, changes in temperature and aridity do not contribute to th.....»»
Loss of "nitrogen fixers" threatens biodiversity, ecosystems, say biologists
Mississippi State University is part of a European-American collaboration studying how human activities, like fertilizer use and pollution, are impacting nitrogen-fixing plants which are crucial for maintaining healthy ecosystems by adding nitrogen t.....»»
DNA-binding C2H2 zinc finger proteins also regulate RNA processing, researchers discover
Researchers at the University of Toronto have shown that an important class of DNA-binding factors can also bind to RNA, regulating gene expression through various mechanisms. The study significantly expands our understanding of these proteins' funct.....»»
Protein signaling pathway provides insights into cell migration and cancer metastasis
The innate immune response is the body's first line of defense against infection, and a successful immune defense takes a village: a combination of physical barriers, chemical attacks, and an army of specialized white blood cells. But maintaining and.....»»
Testing effects of perennial cover crops on soil health and corn production
Corn crops have a voracious appetite for nitrogen. Purdue University scientists are investigating whether mulching Kura clover, a perennial legume, can provide sufficient nitrogen for corn, thus reducing the need for synthetic fertilizers while enhan.....»»
