Agrobacterium tumefaciens pTiA6 virE promoter has a vir box, an inverted repeat (IR) sequence, a putative -35 region and a consensus -10 region. To study how the IR sequence of the virE promoter plays a role in virE gene expression, various mutants were constructed by base substitution and deletion in the virE promoter region. Substitution of the 3'-end(More)
We reported previously that chloroplast DNA binding factors bind to therbcL promoter R2 (-33 to 229 from ATG) region inZea mays. In this study, we investigated transcriptional activity in the high salt extracts of chloroplast, and identifiedrbcL R2 region-specific binding proteins in high-salt extracts. In-vitro transcription and dot blot assays revealed(More)
A PCR-linked reverse DNA hybridization method using two different specific rpoB DNA probes (Avp and Intp) of Mycobacterium avium and Mycobacterium intracellulare, respectively, were evaluated for the differentiation and identification of M. avium and M. intracellulare culture isolates. Among the 504 culture isolates tested by this method, 48 strains showed(More)
