Abstract: | Rhizobitoxine is synthesized by the legume symbiont Bradyrhizobium elkanii and the plant pathogen Burkholderia andropogonis. Rhizobitoxine competitively inhibited 1-aminocyclopropane-1-carboxylate (ACC) synthase bLE-ACS2 from the tomato, a key enzyme in the pathway of ethylene biosynthesis. Based on this inhibition of ACC synthase, we have developed a new assay for rhizobitoxine. |
