Annotated Information

Gene Symbol

  • Os05g0454200 <=> bgl, OsRopGEF10

Function

  • Map-based cloning revealed that the bgl locus encodes OsRopGEF10, one of eleven OsRopGEFs in rice. RopGEFs (guanine nucleotide exchange factors for Rop) activate Rop/Rac GTPases, acting as molecular switches in eukaryotic signal transduction by replacing the bound GDP (inactive form) with GTP (active form) in response to external or internal cues.
  • In yeast two-hybrid assays, OsRopGEF10 interacts with OsRac1, one of seven OsRac proteins; consistent with this, both proteins are localized in the plasma membrane.
  • OsRopGEF10 activates OsRac1 to turn on the molecular signaling pathway for SP development.


Expression

  • In agreement with the timing of SP initiation on the leaf epidermis, OsRopGEF10 is most strongly expressed in newly developing leaves before emergence from the leaf sheath.
