Abstract

A quantitative analysis of organic acid in leaves of barnyard grass revealed that the contents of trans-aconitic acid were high, suggesting that this compound may act as an antifeedant against brown planthoppers. However, trans-aconitic acid could not be detected in the phloem sap which was considered to be the main nutrient source for brown planthoppers. trans-Aconitic acid was formed in vitro from cis-aconitic acid through the aconitate isomerase activity which was detected only in the leaf sheath, but not in the leaf blade.
