Abstract
Changes in accumulation of total phenolics,phenolic acids,phenolic polymers and activity of cell wall bound peroxidase (POD) were investigated in leaves of rice exposed to nickel treatment.Ten soluble phenolic acids and seven bound phenolic acids were detected.The levels of soluble chlorogenic acid and salicylic acid were significantly promoted by nickel treatment,whereas the contents of their bound forms remained unchanged.Nickel treatment evidently increased the concentrations of both soluble and bound ferulic acid.However,nickel treatment led to a significant decrease in the contents of soluble syringic acid and p-coumaric acid but an increase in those of their bound forms.Moreover,the pronounced accumulation of phenolic polymers and enhancement in activities of cell wall bound POD,either with ferulic acid or syringaldazine as its substrate,were registered in rice leaves following nickel treatment.The present results combined with the previous study suggest that the accumulation of phenolic acids and phenolic polymers are involved in the establishment of nickel-induced resistance against bacterial blight in rice.
