Published Calcium can protect potato plants from bacterial wilt
(via sciencedaily.com) Original source Scientists have discovered that calcium plays a significant role in enhancing the resistance of potato plants to bacterial wilt.
Published Novel genetic plant regeneration approach without the application of phytohormones
(via sciencedaily.com) Original source Conventional plant regeneration approaches by cell culture require the external application of plant growth regulators, including hormones. However, optimizing culture conditions can be laborious. Now, researchers have developed a novel plant regeneration system that omits the need for hormone application by genetically regulating the expression of genes that control plant cell differentiation. Their work holds significant potential in the development of genetically modified plants in a simpler and cost-effective manner.
Published Discovery of mechanism plants use to change seed oil could impact industrial, food oils
(via sciencedaily.com) Original source Researchers have discovered a new mechanism of oil biosynthesis and found a way to genetically engineer a type of test plant to more efficiently produce different kinds of seed oil that it otherwise wouldn't make. While the engineering is proof-of-concept, this discovery could lead to improved production of valuable oils used in food and by a range of industries. The modified plant overcame metabolic bottlenecks and produced significant amounts of an oil similar to castor oil that it doesn't naturally produce.
Published Unlocking the genetic mysteries behind plant adaptation: New insights into the evolution of a water-saving trait in the pineapple family (bromeliaceae)
(via sciencedaily.com) Original source Researchers have achieved a breakthrough in understanding how genetic drivers influence the evolution of a specific photosynthesis mechanism in Tillandsia (air plants). This sheds light on the complex actions that cause plant adaptation and ecological diversity.
Published Fixin' to be flexitarian: Scrap fish and invasive species can liven up vegetables
(via sciencedaily.com) Original source Greening the way we eat needn't mean going vegetarian. A healthy, more realistic solution is to adopt a flexitarian diet where seafoods add umami to 'boring' vegetables. A gastrophysicist puts mathematical equations to work in calculating the umami potential of everything from seaweed and shrimp paste to mussels and mackerel.
Published AI deciphers new gene regulatory code in plants and makes accurate predictions for newly sequenced genomes
(via sciencedaily.com) Original source Elucidating the relationship between the sequences of non-coding regulatory elements and their target genes is key to understanding gene regulation and its variation between plant species and ecotypes. Now, an international research team developed deep learning models that link gene sequence data with mRNA copy number for several plant species and predicted the regulatory effect of gene sequence variation.
Published Barley plants fine-tune their root microbial communities through sugary secretions
(via sciencedaily.com) Original source Different types of barley recruit distinct communities of soil microbes to grow around their roots by releasing a custom mix of sugars and other compounds, according to a new study.
Published Scientists released long-term data of ground solar-induced fluorescence to improve understanding of canopy-level photosynthesis
(via sciencedaily.com) Original source A recent study utilized ground-based instruments to measure solar-induced fluorescence (SIF) that reflect plant health and photosynthesis.
Published 'Like a nanoscopic Moon lander': Scientists unlock secret of how pyramidal molecules move across surfaces
(via sciencedaily.com) Original source Scientists have watched a molecule move across a graphite surface in unprecedented detail. It turns out this particular molecule moves like a Moon lander -- and the insights hold potential for future nanotechnologies.
Published Artificial intelligence helps scientists engineer plants to fight climate change
(via sciencedaily.com) Original source Scientists are using artificial intelligence software to analyze plant root systems, laying out a protocol that can be applied to gather data on crop and model plant phenotypes (physical characteristics) more efficiently and with equal or greater accuracy than existing methods.
Published Rubber-like stretchable energy storage device fabricated with laser precision
(via sciencedaily.com) Original source Scientists use laser ablation technology to develop a deformable micro-supercapacitor.
Published Condensed matter physics: Novel one-dimensional superconductor
(via sciencedaily.com) Original source In a significant development in the field of superconductivity, researchers have successfully achieved robust superconductivity in high magnetic fields using a newly created one-dimensional (1D) system. This breakthrough offers a promising pathway to achieving superconductivity in the quantum Hall regime, a longstanding challenge in condensed matter physics.
Published World's chocolate supply threatened by devastating virus
(via sciencedaily.com) Original source A rapidly spreading virus threatens the health of the cacao tree and the dried seeds from which chocolate is made, jeopardizing the global supply of the world's most popular treat. Researchers have developed a new strategy: using mathematical data to determine how far apart farmers can plant vaccinated trees to prevent mealybugs from jumping from one tree to another and spreading the virus.
Published The spiciness of mustard may depend on soil microbes
(via sciencedaily.com) Original source New study finds microbes may influence the taste of mustard seeds.
Published Magnetic with a pinch of hydrogen
(via sciencedaily.com) Original source Magnetic two-dimensional materials consisting of one or a few atomic layers have only recently become known and promise interesting applications, for example for the electronics of the future. So far, however, it has not been possible to control the magnetic states of these materials well enough. A research team is now presenting an innovative idea that could overcome this shortcoming -- by allowing the 2D layer to react with hydrogen.
Published More economical and sustainable rechargeable batteries
(via sciencedaily.com) Original source Lithium salts make batteries powerful but expensive. An ultralow-concentration electrolyte based on the lithium salt LiDFOB may be a more economical and more sustainable alternative. Cells using these electrolytes and conventional electrodes have been demonstrated to have high performance. In addition, the electrolyte could facilitate both production and recycling of the batteries.
Published Development of organic semiconductors featuring ultrafast electrons
(via sciencedaily.com) Original source Collaboration has led to the successful observation of these ultrafast electrons within conducting two-dimensional polymers.
Published Atom-by-atom: Imaging structural transformations in 2D materials
(via sciencedaily.com) Original source Silicon-based electronics are approaching their physical limitations and new materials are needed to keep up with current technological demands. Two-dimensional (2D) materials have a rich array of properties, including superconductivity and magnetism, and are promising candidates for use in electronic systems, such as transistors. However, precisely controlling the properties of these materials is extraordinarily difficult.
Published Plant sensors could act as an early warning system for farmers
(via sciencedaily.com) Original source Using a pair of sensors made from carbon nanotubes, researchers discovered signals that help plants respond to stresses such as heat, light, or attack from insects or bacteria. Farmers could use these sensors to monitor threats to their crops, allowing them to intervene before the crops are lost.
