Polar Organizing Protein PopZ Is Required for Chromosome Segregation in Agrobacterium tumefaciens.

Despite being perceived as relatively simple organisms, many bacteria exhibit an impressive degree of subcellular organization. In , the evolutionarily conserved polar organizing protein PopZ facilitates cytoplasmic organization by recruiting chromosome centromeres and regulatory proteins to the cell poles. Here, we characterize the localization and function of PopZ in , a genetically related species with distinct anatomy.
