Abstract

[To achieve fine control of Physarum polycephalum-based computing devices, a diverse library of plasmodium modulators is required. In this chapter, we review our recent findings on the application of genetically transformed plant roots as a chemomodulatory platform for Physarum. Hairy roots produced by genetic transformation with Agrobacterium rhizogenes are a metabolically productive source of bioactive plant compounds. Transgenic roots of the medicinal plant Valeriana officinalis were developed by stable integration of A. rhizogenes root-inducing genes into the plant genome. An axenic hairy root line was massively propagated in vitro and the culture biomass was characterized in Physarum plasmodium. Hairy roots elicited a robust, positive chemotactic response and augmented maze-solving behavior. In a simple plasmodium circuit, introduction of hairy roots stimulated the oscillation patterns of the slime molds surface electrical potential. We propose that the V. officinalis root culture platform is a sustainable source of modulatory biomass for the development of future slime mold computing devices.]
