Abstract:
Interaction between plant and a phytopathogens causes the induction of defense system in plant against that pathogen which is regulated by a complex network of different signals, as a result of which they produce a large amount of secondary metabolites i.e., phenolic compounds, PR proteins and other enzymes. Plant β-1,3-glucanases are the major PR proteins and belong to the PR-2 family, which are believed to play an important role in plant defence against the phytopathogens. So this study was carried out to analyze the modification in β-1,3-glucanases specific activity in Sesame (Sesame indicum L.) plant after the infection with the pathogen [Macrophomina phaseolina (Tassi) Goid.]. For the experiment, 7 days and 14 days old Sesame plants were used. The specific activity of β-1,3-glucanases enzyme in infected plants was considerably exceeded in contrast to control plants. The obtained results give important information concerning the plant-pathogen interactions, in the defense response for Sesame improvement programs seeking the adaptation to diverse range of fungal attack along with adverse environmental factors.
