Comparative analysis of ARF18 proteins from zy72360 and R1. (A) Amino acid alignments of ARF18 proteins from other species with rapeseed ARF18. The black lines indicate the three conserved domains. (B) Nuclear localization of the ARF18-GFP fusion protein in tobacco epidermal cells. Cells transformed with the plasmid were viewed under a fluorescent filter to show GFP (Left), under a bright field for cell morphology (Center), and in combination (Right). (Scale bar, 50 μm.) (C) Putative conserved domains detected in ARF18 proteins from the alleles of zy72360 and R1.
