Fig. 4From: Expanding the genetic toolbox of Rhodotorula toruloides by identification and validation of six novel promoters induced or repressed under nitrogen starvationFluorescence of strains transformed with the 3877p-GFP reporter cassette. Strains were grown in a BioLector in CN80 and YNB1x medium in triplicates in 96-well plates. Displayed are A: normalized fluorescence of strain UP1a over time, and B: normalized fluorescence of strain UP1b-e over time. Fluorescence was normalized to the scattered light values from the biomass (excitation at 620Â nm). Results are an average of triplicates with shadows showing the standard deviationBack to article page
