Salt stress alters legume responses to symbiotic rhizobacteria by modulating gene expression
Crop legumes are an integral part of sustainable agriculture, as several of these species represent an important protein source for both human and animal populations. Legumes engage in a unique and beneficial interaction with a group of soil bacteria.....»»
Researchers aim to control gene expression by studying the memories of cells
Communication between cells is now believed to activate a memory mechanism that sustains gene expression, a finding based on the work of Dr. Gregory Reeves......»»
Infrared thermal imaging enables reliable assessment of animal stress from distance
An international team of researchers from the University of Turku, Finland, and the University of Tours, France, aimed to validate the use of infrared thermal imaging as a non-invasive tool for assessing stress responses in reindeer. Their findings s.....»»
Beyond needles: Introducing a new, nature-based approach for delivering cargo into egg cells
A new approach for delivering miniature research tools into the interior of egg cells and embryos has been developed at the Marine Biological Laboratory (MBL), resolving a major bottleneck to using the gene-editing tool CRISPR-Cas9 in many research o.....»»
Surprising hormone-related gene activity discovered in the early larval stage of the Malabar grouper
Researchers at the Okinawa Institute of Science and Technology (OIST)'s Marine Climate Change Unit and Marine Eco-Evo-Devo Unit have highlighted patterns of gene activation during Malabar grouper larval development, revealing an unusual early peak of.....»»
A roadmap for using viruses to enhance crop performance
Humans, livestock and companion animals benefit from virus-based vaccines and gene therapies, but crops do not. This paradox is highlighted by an international research group led by the Institute of Molecular and Cellular Biology of Plants (IBMCP) wi.....»»
Crispr-Enhanced Viruses Are Being Deployed Against UTIs
With antibiotics losing their effectiveness, one company is turning to gene editing and bacteriophages—viruses that infect bacteria—to combat infections......»»
How context-specific factors control gene activity
Every cell in our body contains the same DNA, yet liver cells are different from brain cells, and skin cells differ from muscle cells. What determines these differences? It all comes down to gene regulation; essentially how and when genes are turned.....»»
Researchers propose mechanistic framework to explain complex microbe-host symbioses
Virtually all multicellular organisms on Earth live in symbiotic associations with very large and complex microbial communities known as microbiomes. New research has just been published aimed at offering a complete understanding how those relationsh.....»»
Crystallized alternative DNA structure sheds light on insulin and diabetes
The first crystal structure of an alternative DNA shape from the insulin gene has been revealed by a UCL-led research team......»»
Just how dangerous is Great Salt Lake dust? New research looks for clues
As Utah's Great Salt Lake shrinks, exposing more of its playa, concerns grow about the dust the dry lakebed emits. But scientists lack the data to fully understand what pollutants are present in these airborne sediments......»»
Scientists create guidance to help emergency managers prepare for weather hazards of the future
Climate change is fueling more severe storms and floods, droughts and fires, and communities around the world are grappling with how to prepare. Emergency managers regularly meet to examine possible disasters and discuss preparations and responses fo.....»»
Plant scientists link phospholipid sensing with control of gene expression
Plant scientists have long known that phosphorus is a crucial component in plant growth. A major discovery by a Kansas State University (K-State) biologist and her lab is leading to a better understanding of how plants detect and use that resource—.....»»
New mRNA and gene editing tools offer hope for dengue virus treatment
Dengue virus, a painful and sometimes fatal mosquito-borne infection well known in tropical countries, is surging rapidly across the planet. Now, 4 billion people live in places at risk for the disease, like the southeastern United States, which does.....»»
Angiosperms study provides insights into genome evolution after whole-genome duplications
Whole-genome duplication (WGD, or polyploidy) is a common and frequent occurrence in plants, providing raw genetic material for evolution. Homoeologs (duplicate genes from a WGD) often diverge in expression levels, while some still maintain similar (.....»»
Regulatory gene influences shape recognition in medaka fish, scientists discover
Medaka fish that lack functional Hmgn2 genes are unable to distinguish between simple shapes, revealing a new function for the regulatory gene......»»
Research team designs efficient bioenergy crops that need less water to grow
Drought stress has long been a limiting factor for crop production around the world, a challenge exacerbated by climate change......»»
Assorted, distinctive behavior of molten uranium salt revealed by neutrons
In a paper published in the Journal of the American Chemical Society, researchers have documented for the first time the unique chemistry dynamics and structure of high-temperature liquid uranium trichloride (UCl3) salt, a potential nuclear fuel sour.....»»
Scientists develop new TRV vector-based method for peach gene analysis
Peach, a valuable crop within the Rosaceae family, has historically faced challenges in genetic research due to the lack of robust transformation techniques. Current methods are often limited by tissue type and developmental constraints, hindering fu.....»»
Research uncovers new strategy for salt-resistant poplar
Salt stress disrupts plant growth by impairing ion balance and reducing water uptake, posing a significant challenge to agriculture and forestry. Maintaining sodium (Na+) and potassium (K+) balance is particularly vital in woody plants like poplar, w.....»»
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.....»»
