Rice perception of symbiotic arbuscular mychorrhizal fungi requires the karrikin receptor complex

ABSTRACT: In terrestrial ecosystems plants take up phosphate predominantly via association with arbuscular mycorrhizal fungi (AMF). We discovered that the loss of responsiveness to AMF in the rice deletion mutant hebiba is encoded by the alpha/beta fold hydrolase, DWARF 14 LIKE (D14L), which is one of the 26 deleted genes. It is a component of an intracellular receptor complex involved in the detection of the smoke-compound karrikin. On the basis of the early and pronounced hebiba mutant phenotype, we hypothesized that functional D14L is required for the perception of AM fungi prior to contact. Germinated spore exudates of AMF activate pre-contact plant responses. Therefore, we used RNAseq to monitor the transcriptional changes of hebiba and wild type roots in response to germinated spore exudates,
