Salk Institute scientists created a high-resolution atlas showing how droughts affect plant cells. They identified a gene, Ferric Reduction Oxidase 6 (FRO6), that could be targeted to create more resilient crops. FRO6 expression in mesophyll cells partially maintained leaf growth under drought stress.
Researchers studied the genetic response of umbrella acacia and splendid thorn acacia to drought stress. The study found that umbrella acacias prioritize continued growth over water conservation when water is scarce, using up all accessible water to survive severe droughts. In contrast, splendid thorn acacias invest in water conservati...
Researchers discovered that plants rapidly activate a coordinated immune response during drought recovery, prioritizing immunity over growth. This finding highlights the importance of studying the post-drought period and points to new strategies for engineering crops that can rebound more effectively after environmental stress.
The study reveals that grasslands adopt more aggressive strategies than forests when facing water shortages, with plants in grasslands using water aggressively until it's gone. In contrast, forests adopt more conservative strategies, cutting back on water use early to avoid disaster.
Researchers at the University of Missouri discovered that soybeans employ differential transpiration as a natural defense strategy to cool reproductive tissues under extreme weather conditions. This adaptation allows plants to save significant amounts of water while protecting their flowers and seed pods.
A novel, needle-type biosensor allows for real-time monitoring of sucrose uptake in plants, revealing light-dependent stomatal uptake and daily rhythms. The sensor's high sensitivity and stability enable the detection of subtle physiological events, shedding new light on plant biology.
Researchers developed a nonlinear model that captures plants' dynamic response to water stress, revealing 'water spenders' and 'water savers.' The model improves climate predictions and informs water management, providing insights into plant adaptations and soil drydowns.
Researchers found that dual symbioses between trees and mycorrhizal fungi enhance tree fitness, making them less sensitive to drought and nutrient scarcity. This cooperation enables trees to colonize a larger territory and adapt to harsher climates, particularly in dry areas.
Researchers discovered that trees close their stomata earlier than previously thought, prioritizing growth over photosynthesis during drought. This finding has implications for carbon sequestration and climate models, suggesting that trees may absorb less CO2 from the atmosphere during droughts.
A new study reveals that plants prioritize water over gravity during drought conditions, suppressing gravitropism to become more hydrotropic. MIZ1 protein helps attenuate root gravitropism, enabling plants to search for water effectively.
Researchers identify CLE16 peptide as key molecule promoting symbiotic relationship between plants and beneficial soil fungi. Supplementing with this peptide or its fungal equivalent can enhance nutrient exchange and strengthen these traits in crops.
Researchers aim to reduce PFAS contamination risk in agriculture by developing monitoring tools and strategies for remediation. The study focuses on comprehensively understanding PFAS uptake and bioaccumulation in plants, advancing strategies for PFAS remediation in biosolid/soil.
Researchers used CRISPR to modify a tomato gene, resulting in reduced water consumption without affecting crop quality. The discovery holds implications for basic scientific knowledge and could help increase plant yields in dry conditions.
Researchers at MIT have developed a superabsorbent material that can soak up record amounts of moisture from the air, even in dry conditions. The material is made by infusing hydrogel with lithium chloride and has shown to absorb and retain unprecedented amounts of water vapor.
Researchers at Stellenbosch University have discovered a crystalline substance that can readily give up water at temperatures as low as -70 °C. This finding has major implications for the development of materials designed to extract water from the atmosphere.
A recent study at Baskett Forest found that forests reach an ecosystem wilting point between 2-4 weeks of extreme drought, requiring soaking rainfall to rejuvenate. This concept explains how whole forests respond to drought and is essential for understanding their dynamics under climate change.
Researchers at KAUST have developed a rapid and sensitive soil moisture sensor using metal-organic frameworks (MOFs) to optimize water usage in agriculture. The MOF-based sensor shows high sensitivity and selectivity for water even in the presence of metal ions, enabling precise irrigation management.
Researchers found that elevated CO2 levels increase water use efficiency in trees by adjusting stomata opening and closing. The 'g1 number' tool helps predict tree responses under future atmospheric conditions.
Researchers at Nagoya University have developed a new method to study the life cycle of tree roots, shedding light on the decomposition process. They found that fine roots, which control nutrient uptake by trees, are discarded and decompose differently than leaf litter.
Researchers at KAUST have developed a super-adsorbent metal-organic framework (MOF) that can adsorb water at high capacity and release it easily when humidity levels fall. This MOF has been shown to outperform existing materials in terms of capacity, reversibility, and cyclic performance.
Researchers have developed a superporous solid that can absorb up to 200% of its own weight in atmospheric moisture, overcoming challenges of existing porous solids. The material, Cr- soc -MOF-1, maintains its structural integrity and performance over multiple water vapor adsorption-desorption cycles.
Research finds that sweet cherry varieties differ in their susceptibility to skin cracking due to variations in cell wall properties. The study suggests that cell wall physical properties account for the differences in cracking susceptibility among cultivars.
A new study reveals that malic acid is the primary cause of sweet cherry cracking, even at low water uptake levels. The researchers found that artificial juices composed of malic acid or five abundant osmolytes reproduce the effect on fruit cracking.
A team of scientists used advanced mathematical modeling techniques to understand the precise role of soil structure in water uptake by crops. They found that flow properties near the surface of aggregates are a key factor determining overall flow properties in soil.
