Os01g0136400 is a new dominant gene, for bacterial blight resistance in rice, Xa25(t), which conferred resistance to Philippine race 9 (PXO339) of X.

Annotated Information
Function
The xa25, localized in the centromeric region of chromosome 12
, mediates race-specific resistance to Xoo strain PXO339 at both seedling and adult stages by inhibiting Xoo growth. It encodes a protein of the MtN3/saliva family, which is prevalent in eukaryotes, including mammals.
Expression
Transformation of the dominant Xa25 into a resistant rice line carrying the recessive xa25 abolished its resistance to PXO339. The encoding proteins of recessive xa25 and its dominant allele Xa25 have eight amino acid differences. The expression of dominant Xa25 but not recessive xa25 was rapidly induced by PXO339 but not other Xoo strain infections. The nature of xa25-encoding protein and its expression pattern in comparison with its susceptible allele in rice–Xoo interaction indicate that the mechanism of xa25-mediated resistance appears to be different from that conferred by most of the characterized R proteins.
Evolution
Char- acterization of more R genes against Xoo will facilitate evaluation of this inference. In a previous study, we identi- fied and mapped a new R gene against Xoo in rice. This gene localized in rice chromosome 12 and was tentatively named as Xa25(t) (Chen, Wang & Zhang 2002).
