Clusters of ST_ kinases, PKc-like proteins and HTH-Xre players show altered expression during phase variation.

Legend: A description of the microarray is provided in Table 1 legend. Column headings: ID = MXAN # and description refers to annotation; both are derived from the M. xanthus genome [43]; fold change represents the increase or decrease in expression and is derived from coefficient value. +  =  increased expression; -  =  decreased expression.
