Researchers discovered that a plant's internal daily timekeeper coordinates growth by controlling an electrochemical 'language' between different tissues. A key clock component, CCA1, boosts stem elongation while restricting root growth by controlling hormone signaling and proton pump activity.
Scientists at CRAG have made significant progress in understanding sorghum's molecular mechanisms and improving its breeding, focusing on enhancing drought tolerance. The team has identified key genetic mechanisms and developed an efficient transformation method using a ternary vector system.
A study found that bacterial cellulose patches induce plant tissue regeneration by triggering cytokine signaling. The mechanism involves the production of oxidative stress and activation of defense pathways, leading to wound closure.
Scientists have identified a crucial gene, StCDF1, that regulates both tuberization and nitrogen assimilation in potatoes. The discovery offers new insights into enhancing nitrogen utilization, allowing for breeding of climate-smart potato varieties less dependent on chemical fertilizers.
A new study reveals that AGO's N-terminal extension interacts with PRMT5 to catalyze arginine dimethylation, affecting RNA-guided mechanisms. This process fine-tunes gene regulation in plants, impacting development and stress responses.
In this study, researchers identified PIF transcriptional regulators and KAT1 gene as essential players in regulating stomata aperture during day/night cycles. This understanding can be used to optimize plant yield and adaptation to different stressors, such as drought conditions.
Researchers at CRAG have made groundbreaking discoveries on seed germination, identifying key regulatory features and non-coding RNAs that drive the process. The study reveals that transcription restarts much earlier than previously thought, opening up new avenues for investigation into the role of the non-coding genome.
Researchers at CRAG have discovered a key role for AtMC3, a metacaspase protein located exclusively in phloem tissue, in drought stress response. Increasing AtMC3 levels improves plant survival and photosynthetic capacity under water scarcity conditions, offering a potential tool to fine-tune early drought responses.
Researchers have found that iron treatment increases rice's resistance to infection by the pathogenic fungus Magnaporthe oryzae. Exposure to moderate levels of iron triggers a process called ferroptosis, which limits the progression of the fungus and controls the infection.
