Abstract
Greenhouse experiments revealed a reduced viability of a RecA(-) Sinorhizobium meliloti strain in non-sterile soil during a heat period compared with an isogenic RecA(+) strain. The higher sensitivity to heal stress of the S. meliloti RecA(-) strain was demonstrated during short- and long-term heat stress experiments under controlled conditions in a growth cabinet using different microcosm systems. Live/dead staining of the rhizobial cells showed that the increased sensitivity to heat stress of the RecA(-) S. meliloti strain was due to its higher mortality compared to the isogenic RecA(+) strain. These results demonstrate for the first time the importance of the recA function for survival of S. meliloti under heat stress conditions in soil.
