Fluorescence microscopy showing co-anchored EGFP and mCherry encoded by a single plasmid. L. plantarum NC8/Δalr harboring plasmids pLQa-EGFP-S or pLQa-pgsA′-mCherry designed for single-anchoring of mCherry or EGFP were used as controls (×100 objective). White arrows indicate co-localization of EGFP and mCherry in strains harboring pLQa-p′m-ES and pLQa-ES-p′m, respectively
