Identification of lab1, an LCIA-LCIB double mutant. A, Growth of the wild type (cw10) and mutant strains on minimal medium agar plates in different concentrations of CO₂: high CO₂ (5%), low CO₂ (0.04%), and very low CO₂ (0.01%). The mutant genes are shown in parentheses below the strain names. lab1-LCIA is a cell line generated from LCIA-complemented lab1. Strain cia5 is a classic mutant lacking a limiting CO₂ acclimation response. WT, Wild type.
