Contents
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.
