Abstract

Downy mildew disease of pearl millet caused by Sclerospora graminicola is a major threat in pearl millet growing areas. In the present study, partially purified ns-LTP extracts isolated from different seed materials (maize, rice and wheat) and evaluated for their efficacy of hypersensitive response and in inducing defence related enzymes against downy mildew pathogen. Hypersensitive reaction responses (HR) were observed in all the crude ns-LTP treated pearl millet seedlings followed by challenge inoculation and there was also an increase in the activity of defense enzymes. The maximum PAL, POX and LOX activities of 252.3, 77.8 and 59.4 U, respectively was observed in rice ns-LTP treated seedlings followed by maize and wheat seedlings. This combined action of these defence enzymes and HR may account for increased downy mildew disease resistance in pearl millet.
