Researchers from Chiba University identified a previously unreported gene, LIRI1, which plays a crucial role in regulating the balance between starch and lipid storage in plant leaves. The study suggests that LIRI1 promotes carbon allocation by activating starch production and inhibiting starch degradation.
A team of researchers at MIT has developed a system that makes pesticides stick to plant leaves, reducing waste and costs for farmers. The new technology, which involves coating droplets with an oily material, improves the 'stickiness' of the droplets by up to a hundredfold.
Researchers from Uppsala University found that lymphatic endothelial cells have a lobate shape due to their capacity to change shape and increase overlap between cells. This shape supports resilience to changes in fluid volume and is also found in plant leaves.
A new study found that plant leaves are coated with diverse RNA molecules that may play a role in shaping microbial communities. The RNA present on the leaf surface can regulate gene expression in microbes, potentially impacting plant health and environmental interactions.
A team of researchers developed a novel sensor that attaches directly to the underside of plant leaves to measure leaf color without blocking sunlight. The sensor can track changes in the same spot over time and provides fine-tuned readings for real-time monitoring.
A KAUST-led study reveals that plant trait diversity increases above an aridity threshold of 0.7, challenging the view that harsh environments reduce biodiversity. The research found that chemical and morphological traits respond similarly to changes in aridity and grazing pressure.
A study found that invasive cicad aulacaspis scale alters leaf litter decomposition dynamics of cycad species, releasing nutrients too quickly. This damage threatens ecosystem balance and conservation efforts in invaded islands.
Researchers use laser scanning to generate 3D models of sugar beet plants, capturing essential characteristics for AI-assisted crop improvement. The 3D models are reproducible and freely available, enabling efficient and cost-effective plant breeding in resource-poor settings.

Scientists at Brookhaven Lab demonstrate new genetic strategy to boost plant oil content by protecting the oil-protector protein, resulting in 54% more oil accumulation in leaves and 13% more in seeds. This approach can increase biomass energy content and provide sustainable fuels.
The study explores the impact of light conditions on plant hydraulic conductance and water demands, revealing adaptive strategies for improved crop productivity. Shaded leaves exhibit higher water-use efficiency due to reduced transpiration, offering insights into optimizing agricultural practices.
Scientists at Okayama University have identified a membrane transporter, SIET4, in rice leaves that facilitates the localization of silicon. This discovery reveals intricate processes involved in Si deposition, enabling plants to accumulate high levels of silicon and survive environmental stresses.
A research team developed a radiative transfer model for plant leaves in the thermal infrared spectrum and found that as the cuticle layer decreases, leaf reflectance increases with decreasing water content. This study provides essential theoretical foundations for understanding TIR spectral behavior of leaves.
Researchers developed an image analysis algorithm that can automatically measure Arabidopsis thaliana stomatal aperture with high accuracy and speed. The technology also includes a portable imaging device for non-destructive observation using intact plants, allowing for rapid measurement of subtle changes in stomatal aperture.
A team of researchers found microplastics in water trapped in plant leaf axils, a first-time discovery that highlights the global risk of contamination. The study, conducted in Slovakia, used teasel phytotelmata, small aquatic ecosystems formed by plants, to detect the presence of microplastics.
A new study shows that community science activities can produce high-quality taxonomic data sets, empowering community scientists and supporting biodiversity discovery. Thousands of microscopic liverwort leaves were measured by community scientists over two years, with surprising accuracy.
Researchers found that cats' damage to catnip releases higher amounts of strong insect repellents, which are 10-fold higher than from intact leaves. This altered iridoid mixture promotes a prolonged response in cats, effectively repelling mosquitoes.
Researchers at the University of Copenhagen have discovered that plants defend themselves against herbivores by redirecting their defenses to younger leaves, using substances like glucosinolates found in wasabi and mustard. This self-adjustment helps ensure the survival of future generations.
A research team led by Barbara Mazzolai has created a soft, biodegradable, and soluble velcro that mimics the micro-hook structure of leaves on the 'catchweed' plant, enabling devices for environmental monitoring and precision farming. The technology reduces pesticide use and promotes sustainable agriculture practices.
