The rice Os02g0120800 was reported as OsRacB in 2006 [1] by researchers from Korea.

Annotated Information

Gene Symbol

  • Os02g0120800 <=> OsRacB,RacB

Function

  • OsRacB functions as a potential regulator for a basal disease resistance pathway in rice.

Phenotypic analysis

  • Transgenic rice plants over-expressing OsRacB showed increased symptom development in response to rice blast pathogens.
  • Additionally, fluorescence microscopy of green fluorescent protein (GFP):OsRacB-transformed onion cells and Arabidopsis proto-plasts revealed OsRacB association with plasma membrane (PM), suggesting that PM localization is required for proper function of OsRacB.

Expression

  • Its mRNA was strongly expressed in leaf sheath (LS) and in panicles, but was very weakly expressed in young and mature leaves.
  • The basal mRNA level of OsRacB in LS of two-week-old seedlings was strongly down-regulated upon wounding by cut and treatment with jasmonic acid.
  • A dramatic down-regulation in the OsRacB transcripts was also found in plants inoculated with the blast pathogen, Magna-porthe grisea.

Evolution

  • OsRacB is a single copy gene in the genome of rice, shared 98% identity with HvRacB at the amino acid level.

You can also add sub-section(s) at will.
