Reengineering a hormone receptor- a new strategy to counter defense hijacking

Recent studies have identified the plant jasmonate (JA) hormone receptor as one of the common targets of pathogen virulence factors. In this collaborative study recently published in the Proceedings of the National Academy of Science, Li Zhang et al. modified the JA receptor and showed that transgenic Arabidopsis plants with the modified JA receptor gained resistance to certain bacterial pathogens that secrete a potent JA-mimicking toxin, but not at the expense of susceptibility to pests and other pathogens.
