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 beta-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. (C) 2018 Elsevier B.V.
