Organization diagram of response regulator genes and proteins in the M. xanthus genome. RR genes were divided into three categories based on genetic organization. In the second layer, RRs are divided according to the presence or absence of output domains. In the third layer, RRs are divided according to transcriptional regulation during development. Note that in the third layer, not all RR genes are included because they are not all present on the M. xanthus DNA microarray or they were not tested by qRT-PCR.
