Abstract

The Sinorhizobium-legume interaction is sensitive to a number of environmental factors: one of the important stresses is soil acidity. Low pH imposes severe constraints on legume productivity. In the Sinorhizobium-Medicago partnership, prokaryotic partner is the most acid-sensitive. The isolation of acid-tolerant Sinorhizobium strains from the eastern and southern Mediterranean rim have allowed the successful development of medic pastures on over I million ha of land in Western Australia, posing two important questions: • How do acid-tolerant strains differ from acid-sensitive counterparts? • How do agriculturally important root nodule bacteria respond to low pH? Knowledge of the genetic circuits required and activated by the cell in acidic conditions is vital to understand the response and survival of bacteria in these conditions. The molecular basis of acid tolerance has been investigated with several approaches (Glenn et al. 1999).
