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.....»»
Realizing in situ electron paramagnetic resonance spectroscopy using single nanodiamond sensors
Researchers have used the nitrogen-vacancy (NV) center inside a single nanodiamond for quantum sensing to overcome the problem of random particle rotation. Their study is published in Nature Communications......»»
Why are so many migrant families still separated? Chaos in the data
Five years since the retraction of the Trump-era zero-tolerance policy on illegal border crossings, which resulted in the separation of more than 5,000 children from their families at the U.S.-Mexico border between 2017 and 2021, a task force is stil.....»»
The true costs of corn
A model examines farmers' profits and the health and environmental costs of growing corn in the US Midwest, where about 20% of the world's corn is grown. Corn farming involves applying fertilizer or manure to provide the crop with nitrogen, a vital n.....»»
New ammonia reaction could offer a sustainable source of nitrogen
A big goal in chemistry is to find a simple way to produce amines from ammonia and unsaturated hydrocarbons. Catalytic addition to activate and transfer ammonia would not give rise to any waste. Hence, the process would be sustainable......»»
A high-quality Bougainvillea genome helps to explore evolutionary history of a pigment biosynthetic pathway
Bougainvillea, a widely appreciated ornamental shrub, originates from South America and stands out due to its vibrant bract colors, which are believed to result from betalain accumulation. Although Bougainvillea has important ornamental and prophylac.....»»
JcSEUSS1 shown to play negative role in regulating reproductive growth of Jatropha curcas
In Arabidopsis, rice and tomato, the SEUSS gene encodes a transcriptional adaptor as well as a nuclear localization protein that is widely expressed in many developmental stages and organs. However, the function of SEUSS has not been reported in wood.....»»
Genome editing vs natural mutation for variations in tomato size
For tens of thousands of years, evolution shaped tomatoes through natural mutations. Then, humans came along......»»
Researchers: There is a need for more accurate accounting of nitrous oxide from agricultural crop residues
There is a need for changing the way of accounting greenhouse gases from agriculture. The current inventory of nitrous oxide from plant residues relies solely on the amount of nitrogen in the residues, while crucial factors such as the degradability.....»»
Scientists discover how low phosphorus regulates rice architecture and nutrient uptake
Researchers led by Dr. Wang Bing and Li Jiayang from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences have shown that low phosphorus activates the biosynthesis and signaling of strigoalactones to regulate plant a.....»»
The dark side of the American lawn
The American residential lawn is, for many, an iconic landscape and about half of homeowners in the U.S. use fertilizer to keep their yards green and lush. Some proportion of the nitrogen in this fertilizer enters the broader environment, with negati.....»»
Management zone maps of little use to corn growers, study finds
A multiyear analysis tested whether management zone maps based on soil conditions, topography or other landscape features can reliably predict which parts of a cornfield will respond best to higher rates of seeding or nitrogen application. The study.....»»
Nitrogen enrichment delays the emergence of an aridity-induced threshold for plant biomass
Crossing certain aridity thresholds in global drylands can lead to abrupt decays of ecosystem attributes such as plant productivity, potentially causing land degradation and desertification. It is largely unknown, however, whether these thresholds ca.....»»
Unlocking the secrets of cold tolerance: A dive into tomato plants" molecular responses to chilling stress
Cold sensitivity poses a significant challenge for certain essential crops. While there's an indication that these plants may possess cold acclimation capabilities, the molecular dynamics, particularly involving the CRT binding factor (CBF) family, a.....»»
Exploring the genetic potential of eggplant"s wild relatives for sustainable agriculture
In the pursuit of sustainable agriculture, enhancing nitrogen use efficiency (NUE) in crops stands as a primary objective. With the prolific use of nitrogen (N) fertilizers since the 20th century, agricultural productivity has seen remarkable growth......»»
Organic nitrogen aerosol is an important contributor to global atmospheric nitrogen deposition, finds study
New research emphasizes the previously underestimated significance of atmospheric ON aerosol depositions on ecosystems. Additionally, the ecological effects of ON aerosol depositions are anticipated to increase due to global warming and the decrease.....»»
Three weeks later, Apple Watch is still struggling with a watchOS 10 weather bug
I’ve got a fairly high tolerance for software bugs. It comes with the territory when running beta software for most of the summer. I don’t even mind when my iPhone tells me it wasn’t on for much of the night. It happens. This Apple Watch weathe.....»»
Apple objects to Australia plan to regulate Apple Pay
Australia is set to treat digital wallet apps such as Apple Pay under the same regulations as credit cards, but Apple says this will "stifle innovation."Apple Pay on an Apple WatchApple has previously said that it sees the proposed regulation is "con.....»»
Examining the role of methylation in vernalization and the photoperiod pathway: A potential flowering regulator?
Recognized as a pivotal developmental transition, flowering marks the continuation of a plant's lifecycle. Flowering time determines the length of plant reproductive period and environmental adaptability. The correct flowering time is very significan.....»»
Novel sustainable coupling technology proposed for carbon-to-acetylene process
The carbide-based carbon-to-acetylene (C2H2) process is a simple pathway to convert various sources of carbon into acetylene and carbon monoxide directly. However, the current industrial process based on calcium carbide (CaC2) is restricted by high e.....»»
Study explores how risk tolerance changes around payday
People living in poverty often struggle from payday to payday. Those who receive government assistance, such as welfare or pensions, must manage scarce resources to make ends meet until the next payment. Researchers from Kobe University, the Max Plan.....»»
