Title

Bradyrhizobium sp. strain ORS278 promotes rice growth and its quorum sensing system is required for optimal root colonization

Other claims from this paper (4)

Intervention effect ORS278 promotes domesticated rice growth.
Intervention effect Cinnamoyl-HSL-deficient QS mutants had reduced rice growth promotion relative to ORS278.
Intervention effect QS mutants were impaired in rice root colonization.
Mechanism Genes controlled by cinnamoyl-HSL appear important in rice association with ORS278.
