Subcellular localization of GI determines its effect on leaf senescence. (A) Photographs showing yellowing of wild-type (Col-0), gi-2, CsV:GI-GFP-NLS, and CsV:GI-GFP-NES leaves. The third and fourth rosette leaves were used for this experiment. DAE, days after emergence. Scale bar: 0.5 cm. (B,C) Fv/Fm ratio (B) and chlorophyll content (C) of leaves of the indicated genotypes at the indicated time points. Data are presented as the mean ± SEM. Six biological replicates were performed. Asterisks indicate significant differences (*p < 0.05, **p < 0.01, ***p < 0.005; Student’s t-test).
