- Reactive oxygen species(ROS) molecules generated by OsrbohA and OsrbohE regulate different signaling pathways in the plant immune response.

Annotated Information
Function
- OsrbohA and OsrbohE knockdown lines showed that rapid H2O2 generation is caused by OsrbohA.
- Hypersensitive cell death was decreased only in the OsrbohA knockdown line.
- The researchers further demonstrated that among immune related genes, the induction of EL2 and LOX genes is controlled by ROS generated by OsrbohE, whereas expression of Cht-1 gene is regulated by both OsrbohA and OsrbohE.
Expression
- Real-time RT-PCR using specific primer sets for OsrbohA, OsrbohB, OsrbohD, and OsrbohE showed that mRNA levels of OsrbohA in OsrbohA-RNAi3 were decreased compared to the control cells, whereas no change in OsrbohB, OsrbohD, and OsrbohE expression levels were observed in OsrbohA-RNAi3 (Figure 3A).OsrbohE expression levels were also decreased in OsrbohE-RNAi2; however, mRNA transcripts of the other Osrboh homologs were the same as in control cells(Figure 3B).
- EL2, Cht-1, EREBP1, CCD1, and LOX— were selected and the researchers examined the induction patterns of these genes in OsrbohA-RNAi3 and OsrbohE-RNAi2 cultured rice cells.
