Finding new elicitors that induce resistance in rice to the white-backed planthopper Sogatella furcifera

We used the relative induction of GUS activity as a screening tool for identifying new chemical elicitors that induce resistance in rice to the white-backed planthopper Sogatella furcifera. [Display omitted] Herein we report a new way to identify chemical elicitors that induce resistance in rice to herbivores. Using this method, by quantifying the induction of chemicals for GUS activity in a specific screening system that we established previously, 5 candidate elicitors were selected from the 29 designed and synthesized phenoxyalkanoic acid derivatives. Bioassays confirmed that these candidate elicitors could induce plant defense and then repel feeding of white-backed planthopper Sogatella furcifera.
