Research Abstract

Green leaf hopper is one of the serious rice pests. Rice plant with GRH2 and GRH4 genes shows a high level of the resistance against this insect species. In this study, the mechanism for the resistance has been tried to wlucidated. Ten compounds including one peptide with D-form were isolated and identified as antifeeedants against her.
