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.
Climate change is the top threat to pollinators like bees and butterflies, crucial for biodiversity and food security, according to a new review paper. The study highlights how climate-induced habitat changes and human activities harm pollinators, urging integrated conservation strategies to mitigate these impacts and safeguard our food systems.
Like forests, grassland provides numerous ecological, economic and social benefits. Researchers have investigated ways to maintain and improve these benefits.
“Glowing” plants may predict flash droughts by emitting solar-induced fluorescence (SIF), detected by NASA satellites. Increased plant productivity before a drought reduces soil moisture, indicating risk. These early signals, visible from space, could provide up to three months’ warning, aiding mitigation efforts and improving agricultural planning.
A 23-year study found that barley grown under organic farming conditions developed unique genetic adaptations, enhancing resilience to nutrient and water deficiencies. Unlike conventionally farmed barley, which became genetically uniform, organic barley maintained genetic diversity, aiding adaptation to environmental changes.
Scientists developed a system to create tomato plants with the full genetic material of both parents. By replacing meiosis with mitosis, they produced clonal sex cells, enabling offspring with complete parental genomes. This technique promises more robust, high-yield crops, potentially transforming agricultural practices.
