Arbuscular mycorrhizal symbiosis is conserved across the land plants and is the default nutrient uptake strategy for plants in nature. Plant recognition and accommodation of AM fungi requires signalling through both the α/ß hydrolase DWARF14 -LIKE pathway and the common symbiosis signalling pathway. Loss of D14L completely blocks AM symbiosis and renders roots defective in the normal transcriptional reprogramming required to host AM fungi. In contrast, symbiosis is significantly reduced in CSSP mutants, but fungal contacts can nevertheless still be established. In this talk, epistatic analysis in rice is presented to support the placement of D14L upstream of the CSSP component CCaMK. Phenotypic and gene expression analysis are also presented to suggest NSP1 and NSP2 are essential for AM symbiosis in rice.

Due to having to go online, we are restricting the talks to University of Cambridge and alumni to keep them as informal as possible.
