Comparison of partial nucleotide sequences of S. citri BR3-3X chromosomal (BR3-3X_chr) and plasmid (BR3-3X_pl) sequences to those of available BR3-T arp1 and arp2 genes (BR3-T_arp1 and BR3-T_arp2, respectively). Only the regions containing polymorphic positions are shown. (A) region of arp1 positions 3572 to 3800 (AJ297706). (B) region of arp1 positions 4118 to 4177 and (C) region of arp1 positions 4658 to 4717). S. citri BR3-T arp2 is not available for the last sequence alignment. Gaps are denoted by dashed lines, whereas dots denote identical bases.
