A new framework incorporates plant physiology into fine-scale computer models of wildland fire, improving global fire forecasting. Plants' water and carbon dynamics influence combustion and heat transfer, affecting fire behavior and effects.
Cambridge researchers discovered that plants regulate the chemistry of their petal surface to create microscopic three-dimensional patterns reflecting different wavelengths of light, visible to bees. These patterns act as diffraction gratings producing an iridescent optical effect, which is essential for attracting pollinators.
Researchers at Kyushu University developed a new method to create highly detailed 3D models of plants and animals. Over 1,400 models are now publicly available for use in education, research, and virtual exploration.
A team of researchers developed a deep learning pipeline to analyze vascular system images of plants with high accuracy. The pipeline can detect vascular bundles, identify specific zones, and perform statistical analysis of traits in different stem internodes. This study has the potential to improve crop resilience and food security.
Research reveals Arisaema urashima's thread selectively reels in fungus gnats, a key pollinator, by trapping them inside the spathe. The plant's 'fishing rod' appendage also reduces fruiting rate if removed, emphasizing its crucial role in attracting primary pollinators.
Researchers from Tel Aviv University and the Hebrew University discovered charcoal remnants from olive trees at the Chalcolithic site of Tel Zaf, indicating intentional cultivation around 7,000 years ago. This marks the earliest evidence of domestication of a fruit tree worldwide.
A study published in Journal of Pharmaceutical Analysis found that the quality of mistletoe, a traditional Chinese medicine, is affected by its host plant. The researchers used metabolomics to investigate the influence of host plants and environmental factors on mistletoe's medicinal qualities. The results show that both host plants an...
Great Salt Lake wetland plants can accumulate hazardous metal pollution, which can be passed up the food chain to herbivorous insects. This study found high concentrations of lead, mercury, and other metals in plant tissues, threatening terrestrial ecosystems.
Researchers from the University of Zurich and University of Montréal developed a method to assess plant biodiversity across ecosystems using satellite imaging spectrometry. The study found that spectral diversity calculations can capture differences in plant community composition across all ecosystems studied, allowing for targeted fie...
Researchers discover that type 1 TPCs encode SV channels in plant vacuoles, while type 2 TPCs likely encode distinct ion channels. This study provides functional and evolutionary insights into the TPC family in plants, shedding light on their role in plant growth and defence mechanisms.
Researchers discovered that redwood trees have two functionally distinct leaves: one type specializes in converting sunlight into sugar through photosynthesis, while the other absorbs water. This adaptation allows the world's tallest trees to survive in a range of conditions, from wet forests to dry environments.
A study by New York University researchers found that plants make a trade-off between regeneration and defense responses after injury. The researchers used drugs typically used in neurobiology research to study the plant's responses to injury and found that targeting glutamate receptors can boost regeneration.
The study found that the distinctive pattern on the underside of the leaves is crucial for their size and strength. The unique vascular structure allows the plants to occupy a large surface area while maintaining low biomass.
Researchers at TUM explore the use of living trees in architecture, using photogrammetry and skeleton extraction to design structures that adapt to tree growth. They demonstrate a pavilion with a roof structure optimized to follow the shape of supporting branches.
A new study reveals that balancing iron and phosphorus levels is crucial to prevent chlorosis, a condition associated with yellowing leaves. The research team found that removing phosphorus can help restore photosynthesis, highlighting the need for more environmentally friendly agricultural practices.
Researchers used computational modeling and developmental genetic techniques to study grass leaf formation, finding that current theories are likely incorrect and a 19th-century proposal is closer to the truth. The discovery sheds light on how simple growth rules can generate diverse leaf shapes.
Plant scientists can now image above and below-ground structures with unprecedented clarity, revealing new insights into biological processes. The development of three-dimensional X-ray microscopy enables the observation of microscopic molecular and cellular processes driving plant phenotypes.
Researchers developed a cost-effective protocol for plant sample preparation and visualization, eliminating the need for stains and dyes. The new method harnesses the natural autofluorescence of tissues in plants, allowing for rapid visualization of plant anatomy across diverse taxa.
A team of scientists led by Assistant Professor Lae-Hyeon Cho identified a single mutation in the gene that codes for cytidine triphosphate synthase (CTPS), an enzyme crucial for early endosperm development. The study showed that overexpressing CTPS in genetically modified rice plants results in a larger endosperm, opening up opportuni...
