      abstract     = {Soil bacteria such as pseudomonads may reduce pathogen
                      pressure for plants, both by activating plant defence
                      mechanisms and by inhibiting pathogens directly due to the
                      production of antibiotics. These effects are hard to
                      distinguish under field conditions, impairing estimations of
                      their relative contributions to plant health. A split-root
                      system was set up with barley to quantify systemic and local
                      effects of pre-inoculation with Pseudomonas fluorescens on
                      the subsequent infection process by the fungal pathogen
                      Fusarium graminearum. One root half was inoculated with F.
                      graminearum in combination with P. fluorescens strain CHA0
                      or its isogenic antibiotic-deficient mutant CHA19. Bacteria
                      were inoculated either together with the fungal pathogen or
                      in separate halves of the root system to separate local and
                      systemic effects. The short-term plant response to fungal
                      infection was followed by using the short-lived isotopic
                      tracer 11CO2 to track the delivery of recent
                      photoassimilates to each root half. In the absence of
                      bacteria, fungal infection diverted carbon from the shoot to
                      healthy roots, rather than to infected roots, although the
                      overall partitioning from the shoot to the entire root
                      system was not modified. Both local and systemic
                      pre-inoculation with P. fluorescens CHA0 prevented the
                      diversion of carbon as well as preventing a reduction in
                      plant biomass in response to F. graminearum infection,
                      whereas the non-antibiotic-producing mutant CHA19 lacked
                      this ability. The results suggest that the activation of
                      plant defences is a central feature of biocontrol bacteria
                      which may even surpass the effects of direct pathogen
                      inhibition.},
