And will be taken up by the plant and will increase the concentration of carbon dioxide around RuBisCo inside the plant and increase its activity and photosynthetic yields.
His research team envisions a series of interacting processes, or feedbacks, that maintained oxygen at very low levels principally by modulating the availability of life - sustaining nutrients in the ocean and thus oxygen - producing photosynthetic activity.
«If trends continue, we can expect probably a doubling of primary production,» in photosynthetic activity undertaken by millions of algae, he adds.
The innovative aspect of this activity was the notion that the concept of macroscopic devices could be extended to the molecular level, and that it was possible to design supramolecular systems that, upon stimulation with external energy stimuli such as UV / Visible light, are capable of performing a variety of specific functions: (i) systems for information processing (e.g., wires, switches, antennas, plug / socket systems, extension cables, memories, logic gates, encoder / decoder, rudimentary neuron - like systems), (ii) devices that when powered by chemical energy or electrochemical energy or by light exhibit machine - like behavior (e.g., piston / cylinder systems, shuttles, lifts, rotary rings, dendritic photo - switchable boxes), and (iii) components for artificial photosynthetic systems.
The seasonal fluctuations are caused by plant - based photosynthetic activity.
Dr. Kiang also relates this work to research in astrobiology, particularly with regard to how photosynthetic activity produces signs of life at the global scale (e.g., biogenic gases like oxygen and photosynthetic pigments like chlorophyll) and how these may exhibit adaptations to alternative environments on extrasolar planets, resulting in other «biosignatures» that might be detected by space telescopes.
