Reverse transcription-PCR analysis of p44 expression in the p44-1/18 and p44-61/18 loci. (A) p44-1 and p44-18 expression in the p44-1/18 locus of strains NY-31, NY-36, and NY-37. (B) p44-61 and p44-18 expression in the p44-61/18 locus of strains MN-1, MN-2, and MN-9. The DNA template control included 0.1 ng of genomic DNA from each strain. RT+ and RT− indicate the presence and absence of reverse transcriptase, respectively.
