The structures of p1300BMGFP, p1300BMGFPA, p1300BMGFPB, p1300NMRFP and p1300NMRFPA. GFPs include the GFP expression cassettes without PTS (GFP), with PTS1 (GFPA), and with PTS2 (GFPB); RFPs include the RFP expression cassettes without PTS (RFP) and with PTS1 (RFPA). BAR and NPTII represent the BAR and NPTII cassettes respectively; and MPG1P is the MPG1 promoter
