报告摘要：Photosynthesis is crucial for a sustainable food and energy supply. However, our staple crops primarily harness blue and red light, leaving green light untapped. Diatoms, ocean-dominating algae, efficiently harvest green light, suggesting a potential avenue for complementing crop photosynthesis. We've used genetic approaches to uncover biosynthetic pathways for unique chlorophylls and carotenoids in diatoms, aiming to engineer these into plants. Under stress conditions, like nitrogen deprivation, light-harvesting chlorophylls and carotenoids decrease. We're working on maintaining photosynthesis under such conditions, potentially reducing nitrogen fertilizer costs. A large-scale screen in a model green alga identified mutants displaying altered photosynthetic acclimation under nitrogen deprivation, offering insights into decoupling photosynthesis repression from nitrogen deprivation stress.
