FIG. 3

Southern blot analysis of genomic DNAs from scotophobic and phototactic mutants by probing with an SmaI fragment of the R. centenum chemotaxis gene cluster. (A) Diagram of the che gene cluster and flanking sequences along with relevant restriction sites. (B) Genomic DNA samples digested with ApaI. (C) Genomic DNA samples digested with SmaI. Lengths of DNA markers and fragments are marked in kilobase pairs on the left. W.T., wild-type R. centenum sample. ZJP1177, ZJP1315, ZJA8-25, ZJC2-35, ZJC2-33, ZJC4-20, ZJE6-29, ZJE7-17, ZJF6-4, ZJF7-13, ZJH7-24, ZJI3-1, ZJJ5-26, ZJJ6-5, ZJO3-35, YB300-3, and ZJJ8-2 are samples from the corresponding mutant strains. The loading order in panel C is identical to that in panel B.
