Figure 2From: Sequence comparisons of plasmids pBJS-O of Spiroplasma citri and pSKU146 of S. kunkelii: implications for plasmid evolutionSouthern blotting hybridization of (A) S. citri BR3-3X, BR3-G, BR3-T, and (B) S. citri BR3-M and BR3-P plasmid preparations to an arp1-derived probe. Eco RI-digested S. citri BR3-3X chromosomal DNA and Eco RI-digested and undigested plasmid preparations from BR3-3X, BR3-G, BR3-T, BR3-M and BR3-P are shown. D, digested with Eco RI; U, undigested. Hybridization in the marker lane is due to presence of short pBluescript vector sequences in the probe.Back to article page
