Abstract

Fusarium wilt or Panama wilt disease Banana is one of the most disastrous plant diseases. In the present studies, the response of Grand Naine variety of banana plants, when interacting with dead or alive pathogen, Fusarium oxysporum f.sp. cubense (Foc), a causative agent of fusarium wilt disease of banana were investigated. The induced response of plants was evaluated in terms of induction of defense-related  enzymes, viz., Peroxidase (POX), Polyphenol Oxidase (PPO), ß-1,3 Glucanae, Chitinase and Phenoloics. Plants interacted with live pathogen resulted early induction of defense to check penetration as well as antimicrobial productions. However, pathogen overcome the defense of plant and caused disease. Interaction with dead pathogen resulted in acceleration of defense response in plants and so that plants inoculated with dead pathogen showed resistance to forced inoculation of live pathogens. Results obtained in the present study that the dead pathogen was able to raise defense response in plants and provide resistance to fusariam wilt disease of banana upon subsequent exposure. This study showed that dead pathogen could be a potential candidate like a plant vaccine before the onset of disease to combat fusarium wilt disease of banana.
