      Foxtail Millet Lipoxygenase Activity in Response to Pyricularia setariae Causing Blast Infection    
A. Muni Kumari*, D. Ganga Bhavani, S. Babulla, S. Ayesha Banu
ABSTRACT
 

Foxtail millet is an important staple food having good nutritional values. The fungus Pyricularia setariae causes Blast infection in foxtail millet leading to the crop loss. Lipoxygenase (LOX) activity is essential for a plant in growth, resistance to infections, and stress conditions. The present study focuses on LOX activity in foxtail millet seedlings during the course of germination and infected condition. The resistant variety of foxtail millet seedlings was exhibiting more LOX activity than susceptible seedlings, and pH 6.5 was optimum for the LOX activity. LOX activity was more in foxtail millet leaf when compared with root and stem. LOX activity was more in germinating seedlings on the day three. One-fold increase in LOX activity on infection with P. setariae causing blast infection was observed in resistant seed varieties of foxtail millet..
