Coping with High Temperature: A Unique Regulation in A. tumefaciens
Elevation of temperature is a frequent and considerable stress for mesophilic bacteria. Therefore, several molecular mechanisms have evolved to cope with high temperature. We have been studying the response of Agrobacterium tumefaciens to temperature stress, focusing on two aspects: the heat-shock response and the temperature-dependent regulation of methionine biosynthesis. The results indicate that the molecular mechanisms involved in A. tumefaciens control of growth at high temperature are unique and we are still missing important information essential for understanding how these bacteria cope with temperature stress.
