Defense Response in Slash Pine: Chitosan Treatment Alters the Abundance of Specific mRNAs

Abstract

We used differential display to identify chitosan responsive cDNAs in slash pine cell cultures. Two clones that showed increased mRNA abundance had sequence similarity to genes with roles in major plant defense responses, clone 18 to cinnamic acid 4-hydroxylase, and clone 30 to chitinase.
