Multiple groESL operons are not key targets of RpoH1 and RpoH2 in Sinorhizobium meliloti.

Journal of bacteriology - 1 May 2006

Bittner Alycia N, Oke Valerie

Abstract excerpt

Among the rhizobia that establish nitrogen-fixing nodules on the roots of host plants, many contain multiple copies of genes encoding the sigma factor RpoH and the chaperone GroEL/GroES. In Sinorhizobium meliloti there are two rpoH genes, four groESL operons, and one groEL gene. rpoH1 mutants are defective for growth at high temperature and form ineffective nodules, rpoH1 rpoH2 double mutants are unable to form...
