- Key message
- We silenced OsCOI1 in rice plants via RNA interference (RNAi) to determine the role of OsCOI1 in rice defense against rice leaf folder (LF) Cnaphalocrocis medinalis, a chewing insect, and brown planthopper (BPH) Nilaparvata lugens, a phloem-feeding insect
- These results suggest that OsCOI1 is an indispensable signaling component, controlling JA-regulated defense against chewing insect (LF) in rice plants, and COI1 is also required for induction of TrypPI, POD and PPO in rice defense response to LF infestation
- In wild-type rice plants (WT), the transcripts of OsCOI1 were strongly and continuously up-regulated by LF infestation and methyl jasmonate (MeJA) treatment, but not by BPH infestation
- Thus, our study suggests that OsbHLH148 acts on an initial response of jasmonate-regulated gene expression toward drought tolerance, constituting the OsbHLH148-OsJAZ-OsCOI1 signaling module in rice
- Silencing OsCOI1 did not alter LF-induced LOX activity and JA content, but it led to a reduction in the TrypPI content, POD and PPO activity by 62
- MeJA application efficiently suppressed the expression of BR pathway genes, and this inhibition depended on the JA coreceptor OsCOI1

- OsCOI1~OsCOI1a, OsJAZ1~OsTIFY3~EG2, OsbHLH148, a basic helix-loop-helix protein, interacts with OsJAZ proteins in a jasmonate signaling pathway leading to drought tolerance in rice, OsJAZ1, a rice ZIM domain protein, interacted with OsbHLH148 in yeast two-hybrid and pull-down assays, but it interacted with the putative OsCOI1 only in the presence of coronatine
- OsCOI1~OsCOI1a, OsJAZ1~OsTIFY3~EG2, OsbHLH148, a basic helix-loop-helix protein, interacts with OsJAZ proteins in a jasmonate signaling pathway leading to drought tolerance in rice, Furthermore, the OsJAZ1 protein was degraded by rice and Arabidopsis extracts in the presence of coronatine, and its degradation was inhibited by MG132, a 26S proteasome inhibitor, suggesting 26S proteasome-mediated degradation of OsJAZ1 via the SCF(OsCOI1) complex

- OsCOI1~OsCOI1a, OsJAZ8~OsTIFY10c, Involvement of OsJAZ8 in jasmonate-induced resistance to bacterial blight in rice, OsJAZ8 interacted with a putative OsCOI1, which is a component of the SCF(COI1) E3 ubiquitin ligase complex, in a coronatine-dependent manner
- OsCOI1b, OsCOI1~OsCOI1a, Mutation of Oryza sativa CORONATINE INSENSITIVE 1b OsCOI1b delays leaf senescence., The Arabidopsis genome harbors a single COI gene, but the rice (Oryza sativa) genome harbors three COI homologs, OsCOI1a, OsCOI1b, and OsCOI2
- OsCOI1b, OsCOI1~OsCOI1a, Mutation of Oryza sativa CORONATINE INSENSITIVE 1b OsCOI1b delays leaf senescence., The Arabidopsis coi1-1 plants containing 35S:OsCOI1a or 35S:OsCOI1b rescued the delayed leaf senescence during dark incubation, suggesting that both OsCOI1a and OsCOI1b are required for promoting leaf senescence in rice
- OsCOI1~OsCOI1a, OsJAZ9~OsTIFY11a, OsJAZ9 acts as a transcriptional regulator in jasmonate signaling and modulates salt stress tolerance in rice., OsJAZ9 interacts with OsCOI1a, a component of the SCF(COI1) E3 ubiquitin ligase complex, in a coronatine-dependent manner, suggesting that OsJAZ9 is involved in the regulation of JA signaling
- OsCHX14, OsCOI1~OsCOI1a, OsCHX14 is involved in the K+ homeostasis in rice Oryza sativa flowers, Expression profiling confirmed that among 17 CHX genes in rice, OsCHX14 was the only member that showed an expression polymorphism, not only in osjar1 mutants but also in RNAi lines of OsCOI1, another key member of the JA signaling pathway
