Hydrogen peroxide (H(2)O(2)) efflux was measured from Medicago truncatula root segments exposed to purified Nod factor and to poly-GalUA (PGA) heptamers. Nod factor, at concentrations > 100 pM, reduced H(2)O(2) efflux rates to 60% of baseline levels beginning 20 to 30 min after exposure, whereas the PGA elicitor, at > 75 nM, caused a rapid increase in H(2)O(2) efflux to >200% of baseline rates. Pretreatment of plants with Nod factor alters the effect of PGA by limiting the maximum H(2)O(2… CONTINUE READING
