Example of screen for altered fluorescence intensity. a Fluorescence imaging (F 0) of an F/2 agar plate with 52 Nannochloropsis gaditana colonies generated by insertional mutagenesis. Three WT colonies are circled in red, and five colonies selected for either decreased or increased fluorescence signals are circled in white. b Chl signal quantification (fluorescence intensity/colony area) of the samples shown in a. WT colonies are circled in red, and the average of all 52 colonies ± SD is indicated with a green triangle. Strains that were selected for their altered fluorescence intensities are circled in blue
