ARABIDILLO-1 protein targeting. (A) Truncated YFP fusion proteins. Green boxes, Arm repeats; gray box, F-box (residues 45-93); dark blue, remainder of ARABIDILLO-1 protein; light blue, GUS. (B) Nuclear localization of residues 1-93. (C-E) Loss of nuclear localization in mutants (residues 1-93) R4AR6A, R6AK8A, and R7AK8A. (F and G) Cytosolic localization of residues 31-93 and 45-93. (H) Cytosolic localization of 45-93-GUS. (I-K) Cytosolic localization of residues 221-930 (I), 221-829 (J), and 221-769 (K). (L) Cytosolic and nuclear localization of residues 375-930. Representative root confocal sections are shown. Green, YFP; red, propidium iodide. (Scale bars, 25 μm.)
