What is Inhibition of the development of leaf rust (Puccinia recondita) by treatment of wheat with allopurinol and production of a hypersensitive-like reaction in a compatible host about?

The effect of allopurinol [4‐hydroxypyrazolo (3,4‐ d) pyrimidine], a purine analogue inhibitor of xanthine oxidase (XO) enzyme, was studied in the host–pathogen combination of __Triticum aestivum__–__Puccinia recondita__ f.sp. __tritici__. Analysis of purines and pyrimidines in the allopurinol‐treated wheat seedlings showed marked accumulation of xanthine, suggesting the __in____planta__ inhibition of XO activity. In the incompatible wheat–rust interaction application of allopurinol as a drench, even at the highest concentration (50 __μ__m), did not change the hypersensitive reaction phenotype; only the number of lesions was slightly reduced. Allopurinol treatment decreased the augmented rate of electrolyte leakage and lipid peroxidation associated with the hypersensitive response (HR), an effect probably related to the inhibition of rust development by allopurinol. By contrast, in the case of the compatible wheat–leaf‐rust combination the reaction type was strongly affected. The formation of uredia and production of uredospores were diminished or completely inhibited depending on the concentration of allopurinol, which was applied either as a drench (3.125–50 __μ__m) or as a folia
