A study reveals seaweed forests are crucial for oceanic carbon storage, transporting 10 to 170 million tonnes of carbon annually to deep ocean sinks. These findings highlight the importance of protecting and restoring seaweed forests, as they play a vital role in climate change mitigation and biodiversity.
Researchers developed a two-photon microscope technique to observe pollen tube elongation in angiosperms. They discovered signals that attract and repel pollen tubes, ensuring one-to-one guidance for successful fertilization. This intricate regulation optimizes seed production, offering insights to enhance agricultural breeding practices by improving seed yield and germination rates.
A study reveals that Norway spruce forests near recent clear-cuts are highly susceptible to European spruce bark beetle damage. The beetle prefers mature forests in specific soil types. Increased monitoring and adaptive forest management are recommended to mitigate this threat, particularly in Southern Finland.
Orchids nurture seedlings through shared underground fungal networks, researchers found. Orchids transfers sugars to seedlings via these networks, aiding their growth near mature plants. This discovery, solving a long-standing mystery, highlights the crucial role of fungal networks in orchid population support.
Annual flowers, typically considered poor for pollinators, can support bees and insects if the right varieties are chosen. A study found significant variation in pollinator attractiveness among 25 cultivars of popular annuals like begonias and impatiens. This research highlights the potential for pollinator-friendly annuals in home gardens.
Scientists have uncovered how the enzyme carboxysomal carbonic anhydrase (CsoSCA) works in cyanobacteria. This discovery could lead to engineering crops that capture carbon dioxide more efficiently, boosting yields and resilience to climate change.
A study reveals that while most people trust climate scientists, a skeptical minority can impede climate action. Researchers stress that even minority distrust can have significant political consequences, emphasizing the need for scientists to maintain credibility and transparency to bolster public trust and drive climate action.
Researchers identified molecular pathways regulated by the Photoperiod-1 (Ppd-1) gene to boost wheat yields. By editing the ALOG1 transcription factor, they increased branching in wheat and barley, potentially enhancing grain yield. Field trials are underway to test these gene-edited lines, aiming to improve global food security.
Biologists uncovered crucial microbial processes in Georgia’s saltwater marshes. Their study reveals that bacteria in cordgrass roots detoxify sulfides and fix nitrogen, boosting plant health and resilience. These findings, facilitated by advanced genomic technology, underscore the vital role of microbes in coastal ecosystems globally.
Scientists discovered that autophagy, a cellular clean-up process, is crucial for plant root growth. This mechanism, also found in fasting humans, optimizes the “heartbeat” of root tips, aiding water and nutrient absorption. Better understanding this process could enhance crop resilience to climate change.
