Localization of NPQ6, NPQ7 and At3g56830. NPQ6 (b, f, j), NPQ7 (c, g, k) or At3g56830 (d, h, l) transit peptide-GFP fusion was transiently overexpressed in Arabidopsis leaf protoplasts. As a control, GFP alone (a, e, i) was introduced to the protoplasts. Using confocal microscopy, green fluorescence signal (a–d) and chlorophyll fluorescence (e–h) were detected. The superimposed images of green fluorescence and chlorophyll fluorescence (i–l) indicated that NPQ6, NPQ7 and At3g56830 are chloroplast proteins. Scale bar 10 μm
