Abstract
We isolated two major zwitterionic glycosphingolipids (ZGLs) from the phytopathogenic filamentous fungus Trichoderma viride. Structural analyses showed that the ZGLs (designated Tv-ZGL2 and Tv-ZGL3) were the same as the glycosphingolipids ZGL2 and ZGL4 from Acremonium sp., which are described in our previous paper. ZGLs have the following structure: Man(alpha1-6)GlcN(alpha1-2)Ins-P-Cer (Tv-ZGL2) and phosphocholine (PC)-->6Man(alpha1-6)GlcN(alpha1-2)Ins-P-Cer (Tv-ZGL3). To determine whether these ZGLs have functional roles in plant-fungus interaction, we tested to determine whether they would induce defense responses in cultured rice cells. We found that T. viride's ZGLs elicited expression of the PAL and PBZ1 genes, both of which are associated with pathogen resistance. Tv-ZGL2 induced cell death at a moderate rate. Tv-ZGL3, which contains a PC moiety, induced a high level of cell death in rice cells.
