Parasitic weeds represent a major threat to agricultural production across the world. Little is known about which host genetic pathways determine compatibility for any host–parasitic plant interaction. We developed a quantitative assay to characterize the growth of the parasitic weed  Phelipanche aegyptiaca  on 46 mutant lines of the host plant  Arabidopsis thaliana  to identify host genes that are essential for susceptibility to the parasite.  A. thaliana  host plants with mutations in genes involved in jasmonic acid biosynthesis/signaling or the negative regulation of plant immunity were less susceptible to  P. aegyptiaca  parasitization. In contrast,  A. thaliana  plants with a mutant allele of the putative immunity hub gene  Pfd6  were more susceptible to parasitization. Additionally, quantitative PCR revealed that  P. aegyptiaca  parasitization leads to transcriptional reprograming of several hormone signaling pathways. While most tested  A. thaliana  lines were fully susceptible to  P. aegyptiaca  parasitization, this work revealed several host genes essential for full susceptibility or resistance to parasitism. Altering these pathways may be a viable approach for limiting host plant susceptibility to parasitism.
