Induced secretion system of the RR mutant. Surface disinfested BTx623 and RR seeds were grown on sterile MS media (left panel) with and without field soil water extracts (right-top panel) in the growth chambers maintained at 28/25 °C as day/night temperatures. The root images were taken on the 8th day of post germination. Cross section of the root collected from MS media grown seedlings with field soil water extract showed dark red root phenotype only in the RR genotype (right-bottom panel). Scale bar represents 1 cm
