Part of modern cancer therapy is the use of chemicals that kill the tumor. Unfortunately, these chemicals are often very complex, difficult to obtain and thus expensive. Researchers have unravelled the biosynthetic pathway of paclitaxel in Yew plants. This discovery might facilitate the production of this very complex molecule which is currently produced with great efforts and high costs.
Plants emit odours for a variety of reasons, such as to communicate with each other, to deter herbivores or to respond to changing environmental conditions. An interdisciplinary team of researchers carried out a study to investigate how biodiversity influences the emission of these substances. For the first time, they were able to show that species-rich forests emit less of these gases into the atmosphere than monocultures.
Rice, vital for global food security, faces production challenges during the heading-flowering stage. Traditional phenotyping struggles for large-scale analysis, prompting a shift to advanced computer vision and deep learning. While methods like SIFT and neural networks enhance rice panicle analysis, capturing dynamic growth necessitates merging field cameras with deep learning for precise, real-time monitoring.
In a study conducted over five years from 2018, scientists discovered that a well-known protective hormone typically released by plants above ground during periods of stress – a volatile organic compound (VOC) known as methyl jasmonate (MeJA) – possessed a hitherto unknown function. They found that MeJa served as a shared language that allows the plant to communicate with the surrounding layers of microorganisms embedded in the soil.
Aquaporins, which move water through membranes of plant cells, were not thought to be able to permeate sugar molecules, but researchers have observed sucrose transport in plant aquaporins for the first time, challenging this theory.
Researchers develop a model that analyzes the future survival of plants in a changing climate based on how far wind can carry a plant’s seeds.
Iron is an essential micronutrient for plants and is generally found in large quantities in the Earth’s crust. However, its availability to plants is highly dependent on the pH value of the soil. When suffering from iron deficiency, certain plant species release coumarins. Which type of these small secondary metabolites is mainly released depends on the pH value of the soil. Now, a research team has shown how different coumarins are used to maximize iron uptake under acidic and alkaline conditions.
A new study unveils the intricate organization and regulation of ribosomal RNA genes within the complete nucleolus organizer regions (NORs) of Arabidopsis, the first plant with a fully sequenced genome. The research identifies over 70 gene subtypes distributed between NOR2 and NOR4, shedding light on their activation and silencing patterns. The findings, crucial for comprehending NOR epigenetic control, hold broad biomedical relevance and offer a platform for future investigations into NOR evolution.
With land clearance, bushfires, weeds and climate change, small pockets of native vegetation are important for future plant and animal conservation – but do plants in small reserves struggle with reduced habitat for both plants and their pollinators?
The European Plant Science Organisation (EPSO) jointly with over 60 National Coordinators across the globe proudly announce the launch of the seventh edition of the Fascination of Plants Day (FoPD), scheduled to take place on and around May 18, 2024. A celebration of the captivating world of plants, FoPD invites individuals of all ages to engage in plant-based interactive events and activities organised by scientific institutions, universities, botanical gardens, museums, schools, farmers, and companies worldwide.
