Prisoners' Dilemma and Citing Prior Art

Of Algae biofuels and the Prisoner’s Dilemma, note the prior work on regulating antennas by Tony Melis.

For example, from Optimizing Antenna Size to Maximize Photosynthetic Efficiency, ,

Lowering the chlorophyll (Chl) content of photosynthetic tissue is another and potentially more robust strategy to improve light penetration into plant canopies and algal mass cultures. But hasn’t evolution already optimized Chl content in plants and microalgae? No doubt it has for competitive natural habitats where a large assembly of antenna pigments confers a selective advantage. That is, even when photosynthesis is already saturated, intercepting more light deprives a potential competitor that may have otherwise received the light. However, evolution has not optimized Chl content for achieving maximum carbon gain in dense crop monocultures or microalgal mass cultures where competition for resources including light is not a benefit (Anten, 2005). Here, we discuss the theory and physiological factors that need to be considered in optimizing Chl content for improved photosynthetic efficiency and maximum carbon gain by crops and microalgae.


Microalgae with truncated light-harvesting Chl antenna (abbreviated as Tla) have been shown to improve solar-to-biomass conversion efficiencies in mass cultures (Nakajima and Ueda, 1997, 1999; Mitra and Melis, 2008; Beckmann et al., 2009; Melis, 2009).

Does the BD post merely recycle old work?
