We describe the characterization of a novel Tn 5lacZ colonization mutant of the efficiently
colonizing Pseudomonas fluorescens strain WCS365, mutant strain PCL1210, which is at …

A colonization mutant of the efficient root-colonizing biocontrol strain Pseudomonas
fluorescens WCS365 is described that is impaired in competitive root-tip colonization of …

Pre‐replication complexes (pre‐RC) assemble on replication origins and unwind DNA in the
presence of chromatin proteins. As components of Escherichia coli pre‐RC, two histone‐like …

Single-molecule experimentation has contributed significantly to our understanding of the
mechanics of nucleoprotein complexes that regulate epigenetic switches. In this minireview …

In our studies of lac repressor tetramer (T)-lac operator (O) interactions, we observed that the
presence of extended regions of non-operator DNA flanking a single lac operator sequence …
