Genetic manipulation in C. cryptica. Conditional expression using the nitrate reductase promoter. a GFP expression in ASW media, with nitrate as the nitrogen source. b No GFP expression in repressive modified ASW media, with ammonia as the nitrogen source. Chlorophyll and GFP are falsely colored red and green, respectively. Composite images are 3D reconstructions. Scale bars 5 μm
