The N Terminus of Arabidopsis VIT1 Contains a Tonoplast Sorting Signal.
(A) Scheme of VIT1 N terminus mutation constructs and their subcellular localization in Arabidopsis protoplasts.
(B) to (E) Confocal images showing the subcellular localizations of VIT1 N terminus point mutation constructs. The right column shows the scatterplot images indicating the extent of colocalization with the linear Pearson correlation coefficient (rp) and the nonlinear Spearman correlation coefficient (rs). Bars = 10 μm.
