Protection of groundnut plants from rust disease by application of glucan isolated from a biocontrol agent Acremonium obclavatum

Prior treatment of groundnut leaves with glucan isolated from a biocontrol agent, Acremonium obclavatum, protected against the rust disease. Glucan treated leaves showed increased levels of chitinase and β-1,3-glucanase in the apoplastic fluid. An increase in endogenous levels of salicylic acid also...

Description
Summary:Prior treatment of groundnut leaves with glucan isolated from a biocontrol agent, Acremonium obclavatum, protected against the rust disease. Glucan treated leaves showed increased levels of chitinase and β-1,3-glucanase in the apoplastic fluid. An increase in endogenous levels of salicylic acid also was observed in treated leaves. Treated leaves also showed a significant reduction in rust disease development in groundnut leaves. Enhanced activities of glucanohydrolases of treated groundnut leaves might have affected the biotrophic rust pathogen, which is known to colonize in the apoplastic spaces.
