Effects of temperature on the protocooperation between plants and Bacillus amyloliquefaciens S499

Abstract: When applied in open fields, the efficacy of biological control agents may be strongly affected by environmental factors such as temperature and water availability. The protocooperation between Bacillus amyloliquefaciens S499 and plants has been chosen as a model to investigate how temperature and water regime may modulate the beneficial interaction between the two bionts. On this purpose, the effect of temperature on the ability of S499 to induce systemic resistance and to produce surfactin in planta has been investigated in this work.
