“…The observation that non-pathogenic bacteria must be living to induce interactions with plant pathogens is frequently reported, but the opposite has also been noted. Our observations confirm those of HSIEH and BUDDENHAGEN (1974), studying the protection of rice from X. e. pv. oryzae by E. herbieola.…”

Various chromogenic bacteria were isolated from the mowing site in natural and sown meadows and in pastures. Their abihty to protect young ryegrass plants from wilt by simultaneous inoculation with Xanthomonas campestris pv. graminis was tested under low concentrations of the parasite inoculum. From about 200 isolates tested 35 % had a very high protective effect, 45 % a moderate one, and only 20 % had no significant effect. Mixtures of different species of phylloplane bacteria usually gave very good protection. Most of these baeteria live between the leaf-sheaths. In vitro antagonism of the phylloplane bacteria was not related to their protective effect. Avirulent mutant strains of X. c. pv. graminis and pathovars of other grass species, e.g. pv. poae, pv. phlei, and pv. arrhenatheri, have the same protecting effect. Heat killed bacteria were no longer effective.These observations suggest an unspecific reaction of the plant, such as the induction of a general defense mechanism which results in resistance also to the parasite.

“…The in vitro inhibition of the growth of X. c. pv. graminis by certain bacterial strains could be due to acid production lowering the pH of the medium below inhibitory levels, as observed by HsiEH and BUDDENHAGEN (1974). The calcium carbonate got dissolved below the colonies of several isolates, especially yellow ones.…”

Induced Resistance in Pepper Leaves Infiltrated with Purified Bacterial Elicitors from Xanthomonas campestris pv. vesicatoria

Cell components (lipopolysaccharide (LPS), exopolysaccharide (EPS), capsular glycoproteins and the cell envelope) were extracted and purified from cells of compatible and incompatible isolates of Xanthomonas campestris pv. vesicatoria and infiltrated into pepper leaves in an attempt to protect them against a compatible isolate. All cell components induced protection but only EPS and the cell envelope elicited phytoalexins. Therefore, resistance mechanisms other than phytoalexins may exist in pepper leaves and appear to be more effective than phytoalexins.
