Annotated Information

Gene Symbol

  • Os11g0692300 <=> OsXa26,Xa26

Function

  • OsXa26 confers resistance against Xoo at both seedling and adult stages in rice.
  • Xa26 belongs to a multigene family consisting of four members. It encodes a leucine-rich repeat (LRR) receptor kinase-like protein and is constitutively expressed.
  • Significant difference in lesion length was observed among these lines after inoculation with a set of Xoo strains.
  • The resistance conferred by Xa26 is in ̄uenced by the genetic background.

Phenotypic analysis

  • Transgenic plants carrying Xa26 showed enhanced resistance compared with the donor line of the gene in both seedling and adult stages.
