Phenotype: requires elevated CO2 for photosynthetic growth, zeocin resistant

This Rubisco activase knock-out mutant was received from Jim Moroney in 2006 (Pollock et al. 2003). It has been maintained with acetate medium in darkness to prevent selection for extragenic suppressors. The CO2-requiring phenotype may be easier to observe with 10-25 µM ethoxzolamide in the minimal medium plates.
