Fig. 1From: Influence of rhizobacterial volatiles on the root system architecture and the production and allocation of biomass in the model grass Brachypodium distachyon (L.) P. Beauv. In vitro co-cultivation system. B. distachyon Bd21 plantlets were photographed after 10Â days of near-vertical growth without (left) or with (right) exposure to BsuGB03 volatiles. The bacterial compartment contains a Farag et al. [15] medium and the plant compartment contains a Hoagland agar plate. Both growing media are physically separated, which limits plant-bacteria interactions to the exchange of volatiles. The scale bar is 1.75Â cm long. The arrows point the adventitious roots (AR), the secondary roots (SR) and the primary root (PR) locationsBack to article page
