Identification of Pseudomonas syringae pv. tomato genes induced during infection of Arabidopsis thaliana.

abstract：:To investigate the possible role of accessory subunits of Escherichia coli DNA polymerase III holoenzyme (HE) in determining chromosomal replication fidelity, we have investigated the role of the dnaX gene. This gene encodes both the tau and gamma subunits of HE, which play a central role in the organization and funct...
