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.
Satellite data reveals a significant cooling impact of vegetation on land surface temperature in the Arabian Peninsula. The study underscores the potential of greening dry areas to mitigate heat stress. The balance between increased evapotranspiration and reduced albedo determines outcomes, emphasizing the need for sustainable water management in climate change adaptation.
Plants avoid mutational damage buildup by leveraging randomness in a process called segregation. Unlike passing on the same mutation to all offspring, plants distribute inherited damage randomly, with some offspring inheriting more mutations than others. This segregation process, faster in plants than in humans, holds agricultural promise. Understanding how plants handle mutational variations in their DNA could aid crop breeders in introducing beneficial mutations for enhanced yield. The study’s findings advance knowledge crucial for crop breeding and yield enhancement.
