| detection and molecular analysis of plant- and insect-associated bacteria harboring aconitate isomerase involved in biosynthesis of trans-aconitic acid as antifeedant in brown planthoppers. | the activity of aconitate isomerase, which is involved in the biosynthesis of trans-aconitic acid as antifeedant in brown planthoppers, was detected in pseudomonas fluorescens lrb3w1 and pseudomonas putida maff301685 but not in pseudomonas putida maff301684. the enzyme activity was induced in the presence of trans-aconitate, and therefore bacteria showing the enzyme activity were easily detected by their ability to grow on the minimal medium containing trans-aconitate as the sole carbon source ( ... | 1997 | 9216883 |
