Abstract

Abstract: Oligochitosan is an important elicitor that can induce resistance of plants against pathogens. The process and sites of oligochitosan binding to strawberry cells were investigated by the treatment of using labeled oligochitosan with fluorophore 2-aminoacidone and detecting the emission fluorescence by alaser scanning confocal microscopy (LSCM). Oligochitosan can bind to membrane of strawberry p rotop lasts and cell walls in few minutes. the results indicated that p rotop lastsmembrane and cellwalls are the main binding of oligochitosan. The binding of oligochitosan to binding sites is special.

Key words: Oligochitosan, Strawberry, Binding site, Laser scanning confocalmicroscopy
