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.
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.
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.
New research could help breed plants that are more productive as days grow shorter. The research found that when days are shorter, plants have less time to photosynthesize, so they need to be more efficient with the sunlight they do receive. Plants store more sugar as starch during the day so that they have energy to use during the longer night. These findings could help to develop new crop varieties that can grow in a wider range of climates.
Sphagnum divinum, a resilient type of peat moss, is actively evolving in response to hot, dry conditions, defying climate threats. Researchers developed a database with S. divinum’s proteins and a method to determine their functions, shedding light on its adaptive mechanisms. As environmental stressors deplete peatland carbon reserves, understanding genetic resilience becomes crucial. Using high-performance computing and AI, the team predicted structures for S. divinum’s 25,134 proteins, revealing insights into their functions. The findings advance climate resilience understanding and support future research on Sphagnum moss compounds.
A genetic breakthrough unveils the high-iron mutations in peas, presenting opportunities for fortified vegetables and cereals. This discovery, based on a newly mapped pea-genome, could guide gene-editing strategies to enhance iron content in various crops, addressing global anaemia concerns, especially among women. The findings illuminate iron homeostasis in plants, offering prospects for biofortification.
Scientists have long known that chloroplasts help plants turn the sun’s energy into food, but a new study, led by plant biologists, shows that they are also essential for plant immunity to viral and bacterial pathogens.
Plants employ plasmodesmata for cell communication, but protein targeting to these structures is poorly understood. Studying PDLP5 and related proteins, researchers discovered unconventional targeting signals in their extracellular regions, crucial for regulating viral movement. New study aims to uncover the molecular mechanisms behind protein targeting to plasmodesmata, offering insights for plant biotechnology.
