| Research Abstract |
Plants quickly respond to pathogenic invasion. As the result, the secondary metabolism is activated. Therefore, we may use the information obtained from this plant-microbe interaction for secondary metabolite production. For this purpose, we are very much interested in what type of stimulating factors are involved in the activation of the metabolism. We investigated the stimulating factors and we attempted to prepare those, since these eliciting factors can be applicable to produce new secondary metabolites in the plant cell system and a large suply is required. The results of our investigation were listed below.
1) The elicitor activities of deacetylated chitin oligomers to legume plants were investigated.
2) A facile method for preparation of deacetylated chitin oligomers using lysozyme was developed
3) Elicitor-active oligosaccharides from laminaran was purified and thier structures were elucidated.
4) A structure-activity relationship study for elicitor-active oligosaccharide from laminaran was performed.
