| Mutant Symbol | R38 |
|---|
| Allele Symbol | dmi2-4 |
|---|
| Gene and Mutation Location | DMI2 (NORK) (Conserved Gly changed to Glu in the kinase subdomain X which might interact with the substrate) |
|---|
| Symbiotic Phenotype Brief | Calcium flux+, Calcium spiking-, Has+, Hab-, Enod gene induction-, Ccd-, Hac-, Inf-, Nod-, Myc+ |
|---|
| Phenotype Detail | Nod-; defective in calcium spiking; root hair tip swelling (Has) but are blocked for branching (Hab-); block in the induction of ENOD11 and ENOD40; dramatically reduced induction of RIP1; lack cortical cell division; no infection threads (Inf-); no root curling (Hac-) in response to live bacteria; Myc+ phenotype; Recessive |
|---|
| Single gene targeted? | yes |
|---|
| Extra Information | A recent paper by Esseling et al., 2004 showed that when care is taken not to induce touch response, the dmi2 mutant root hairs respond morphologically like the wild type to nod factor. |

| Mutagenesis Method | EMS |
|---|
| Mutant Class | Nod- |
|---|
| Allelism | not allelic to dmi1, dmi3 or nsp1, determined by complementation test |
|---|
| The earliest development stage known to be affected | Calcium spiking |
