DMI3 (The CaM-binding domain and the remaining of DMI3 is deleted. Only first 326 aa of the protein were kept)
Symbiotic Phenotype Brief
Nod+Fix-
Phenotype Detail
Roots transformed with DMI3 1-326 showed strong ENOD11-GUS expression in epidermal cells, primarily of lateral roots, in the absence of Nod factor treatment 53% of root systems. The ENOD11-GUS expression induced by the deletion construct was observed in a similar zone of epidermal cells to that of the ENOD11 induction by Nod factor. No bacterially infected nodules were found in complementation tests with dmi3-1.
Single gene targeted?
yes
Extra Information
The deletion in DMI3 1-326 leads to constitutive substrate phosphorylation in vitro that is independent of Ca2+ and CaM. The DMI3 1-326 mutation is driven by the 35S promoter.
