The CaGPI12 conditional null mutant is made by replacing its native promoter with MET3 promoter by using the pMET3-GFP-URA3 cassette. CaGPI12 is able to rescue the growth defect of the ScGPI12 conditional null strain as compared to the control strain carrying the YepHIS vector alone, suggesting that CaGPI12 functionally complements ScGPI12.
