Biochemical genetic basis of downy mildew resistance in pearl millet

Theoretical and Applied Genetics Aims and scope Submit manuscript

Summary

The study of phenolic content and activities of peroxidase and polyphenoloxidase in relation to the degree of downy mildew infection of 12 pearl millet cultivars revealed that these were linearly related to the degree of resistance at both the 30 and 50 day growth stages. Useful electrophoretic differences in peroxidase and polyphenoloxidase were also observed with respect to the expression of resistance.
