Fluorescence activated cell sorting (FACS) histograms of the trichome fraction harvested in sorbitol-buffer. (A) Preselection of young type VI trichomes in region P1 by the height of the forward scatter (FSC-H) and the area of the forward scatter (FSC-A). This allows the discrimination of single trichome heads and aggregates. The P1 region was selected for further separation based on differential fluorescence as shown in (B). (B) Separation of young type VI trichomes (region P2) and mature type VI trichomes (region P3) based on different ratios between red (PerCP channel) and green (AlexaFluor 488 channel) fluorescences. (A,B) The units are arbitrary units provided by the instrument.
