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.....»»
Study: Vps21 signaling pathway regulates white-opaque switching and mating in Candida albicans
In a paper published in Mycology, a team of scientists present that the conserved Vps21 signaling pathway plays critical roles in the regulation of white-opaque switching and mating in the major human fungal pathogen C. albicans......»»
Study identifies RNA molecule that regulates cellular aging
A team led by UT Southwestern Medical Center researchers has discovered a new way that cells regulate senescence, an irreversible end to cell division. The findings, published in Cell, could one day lead to new interventions for a variety of conditio.....»»
Antisemitism study finds education does not necessarily increase tolerance
New research by government professor Bendan Nyhan shows that the relationship between education and antisemitism varies across countries......»»
Study highlights the benefits of mixing cover crops
A University of Kentucky study titled "Productivity benefits of cereal-legume cover crop mixtures under variable soil nitrogen and termination times" suggests that mixing cover crops is a beneficial strategy for modern agriculture......»»
Influenza viruses can use a second entry pathway to infect cells, study shows
Most influenza viruses enter human or animal cells through specific pathways on the cells' surface. Researchers at the University of Zurich have now discovered that certain human flu viruses and avian flu viruses can also use a second entry pathway,.....»»
Study shows frogs can quickly increase their tolerance to pesticides
Although there is a large body of research on pests evolving tolerances for the pesticides meant to destroy them, there have been considerably fewer studies on how non-target animals in these ecosystems may do the same......»»
Social contagion research explores how ant colonies regulate group behaviors
In the world of social creatures, from humans to ants, the spread of behaviors through a group—known as social contagion—is a well-documented phenomenon. This process, driven by social imitation and pressure, causes individuals to adopt behaviors.....»»
New research reveals how galaxies avoid early death
Galaxies avoid an early death because they have a "heart and lungs" which effectively regulate their "breathing" and prevent them from growing out of control, a new study suggests......»»
Four crucial climate targets the new UK government should adopt immediately
The UK is not on track to meet its climate targets and has no credible pathway to get there. However, a new set of more specific targets would provide some clarity for the country's new government and would ultimately help achieve the overall goal: p.....»»
Photosynthesis powers our world, but what fuels this fundamental process?
It's hard to overstate the importance of photosynthesis, the biochemical pathway by which plants, algae, and certain bacteria convert the sun's energy into the organic material that feeds the entire living biosphere. But there are still aspects of th.....»»
Study reveals impact of postharvest treatments on tomato ripening
Tomato fruit ripening, a process initiated by key gene demethylation, is significantly influenced by postharvest handling practices. These practices, while extending shelf life, can alter ripening dynamics and affect fruit quality......»»
Tomato timekeeper: SlNF-YA3b gene"s role in flowering time revealed
Controlling the timing of flowering in crops is crucial for optimizing yields and adapting to climate changes. Researchers have identified a specific gene in tomatoes that regulates this critical phase, providing a significant step forward in the abi.....»»
Study finds ways to enhance transcription factor activity
Transcription factors regulate gene expression by binding specific sequences on DNA, which is an essential step to producing messenger RNAs from protein-coding genes. Denes Hnisz's lab, in collaboration with Martin Vingron's lab at the MPIMG, has dis.....»»
Controlling magnetism with polarized light: Non-thermal pathway uses inverse Faraday effect
Intense laser pulses can be used to manipulate or even switch the magnetization orientation of a material on extremely short time scales. Typically, such effects are thermally induced, as the absorbed laser energy heats up the material very rapidly,.....»»
Experimental bermudagrasses show varied drought response
In a new study, researchers at Oklahoma State University have unveiled significant variations in drought response among advanced turf-type Bermudagrass experimental genotypes. The study aimed to evaluate the drought tolerance of various Bermudagrass.....»»
Scientists found a nearly indestructible moss that may survive on Mars
A nearly indestructible moss that can survive bursts of gamma rays and liquid nitrogen may be one of the keys to Mars colonization, scientists have … The post Scientists found a nearly indestructible moss that may survive on Mars appeared first.....»»
Out in the cold: Enhancing frost tolerance in wheat
Rugging up against winter chills is a cozy and easy option for most of us. But our crops are facing frosts and freezing temperatures without the warmth of winter woolies. Frost poses a significant threat to agriculture, particularly in Australia's wh.....»»
Nitrogen-using bacteria can cut farms’ greenhouse gas emissions
Nitrogen fertilizers get converted to nitrous oxide, a potent greenhouse gas. Enlarge (credit: Timothy Hearsum) Fritz Haber: good guy or bad guy? He won the Nobel Prize in Chemistry in 1918 for his part in developing the.....»»
New sensing techniques can detect drought tolerance in ancient crops, may inform new breeding programs
Drought is the most devastating environmental stress that farmers face worldwide. With the added pressures of climate change, drought years have become less predictable, more frequent and more severe......»»
Study shows transgenic expression of rubisco factors increases photosynthesis and chilling tolerance in maize
Maize is one of the world's most widely grown crops and is essential to global food security. But like other plants, its growth and productivity can be limited by the slow activity of Rubisco, the enzyme responsible for carbon assimilation during pho.....»»
