t0“Pea SYM8 Symbiosis Gene”
e0“We made a mutation changing the aspartate to valine and identified a missense mutation (changing alanine to valine adjacent to the aspartate residues) in this predicted filter region; both mutations caused a loss of function”

- Intervention effect Mutation of sym8 in R25 blocks nodulation, mycorrhization, and Nod-factor-induced calcium spiking.
- Observation Four new pea sym8 alleles belong to the same complementation group as R25.
- Observation Pea sym8 mutants phenotypically resemble Medicago truncatula dmi1 mutants.
- Observation Pea sym8 mutants map to a syntenic location.
- Intervention effect The cloned pea DMI1 ortholog complements a Medicago truncatula dmi1 mutant for nodulation.
- Observation All five pea sym8 mutants carry mutations in the DMI1 ortholog.
- Observation The pea SYM8 gene is the DMI1 ortholog.
- Observation A predicted SYM8 channel structure has four aspartate residues forming its opening.
- Intervention effect An alanine-to-valine missense mutation in the predicted filter region caused loss of function.
- Observation An arginine-to-isoleucine missense mutation in a proposed linker domain caused loss of function.
