Effects of BR Treatment on the Chitinase Activity of the Intercellular Fluid in Maize

doi:10.7668/hbnxb.2015.S1.065

Abstract

Abstract: Chitin is a major component of most fungal cell wall,but does not exist in plants.But the chitinase are widespread in higher plant,plants can hydrolysis chitin by chitinase and so have the ability to resist the fungus infection.In order to study the mechanism of BR in improving the maize resistance to disease,we analyzed the chitinase activity of the intercellular fluid in maize after BR treatment.The results showed that the chitinase activity had no significant change after 100 nmol/L eBL (Epicastasterone) treatment,but the chitinase activity was lower after 10 nmol/L eBL treatment than that of the control.So there was different effect on maize disease resistance using different concentration of BR.

Key words: Maize, Chitinase, Brassinosteroid
