Defense related enzymes are the key to any resistance or plant pathogen studies. The biochemical response of Sesamum against Macrophomina phaseolina infection was investigated by comparing normal and diseased plants. Induction of infection in Sesamum by Macrophomina induces a significant increase in the activities of polyphenols polyphenol oxidases and phenylalanine ammonia-lyase. The investigation was carried in RT-46 variety at different ages after different time intervals of infection, which shows increase in activities of all defense related proteins to varying degrees at different stages of infection. Induction of the synthesis of enhanced levels of protein along with increasing phenolic content in the inoculated plants activates the defense system in Sesamum against the target pathogen
