Xb15 encodes a PP2C that negatively regulates the XA21-mediated innate immune response.
Contents
Annotated Information
Function
- The rice XA21 protein is representative of the large class of non-RD RKs predicted to be involved in plant innate immunity. XB15 encoded by Xb15 Is an XA21 Binding Protein.
Mutation
- To explore the role of Xb15 in resistance, the researchers examined whether constitutive overexpression of Xb15 would affect resistance to Xoo. The resulting transgenic plants (NTAP-XB15, pollen donor) were crossed with another Kitaake line possessing an N-terminal Myc-epitope-tagged XA21, under control of its native promoter (Myc-XA21, pollen recipient).

Evolution
- The researchers next compared the PP2C domain of XB15 with other evolutionary related proteins from the reference plant species rice and Arabidopsis, such as Arabidopsis POL and POL-like proteins (PLLs) (Figure 2).
