Research Work
& GA negatively regulates rice immunity through repressing JA signaling.
Gibberellic acid is one important phytohormone promoting rice growth. We demonstrated that GA negatively regulate disease resistance against bacterial blight and blast disease. More importantly, the “Green Revolution” gene, semi-dwarf 1 (sd1) significantly enhanced disease resistance. GA negatively regulate disease resistance through repressing jasmonic acid (JA) signaling via DELLA-JAZ interaction and mutual interference.
& MicroRNA156-IPA1 integrate GA and SA signaling to enhance disease resistance.
Ideal Plant Architecture 1 (IPA1, also named OsSPL14) reduces inefficient tiller number, increases panicle branching, and strength culm. We found that microRNA156 reduces disease resistance, while its two target genes, IPA1 and OsSPL7 enhance disease resistance against bacterial blight. IPA1 and OsSPL7 physically interact with SLR1 (Slender Rice 1), the solely DELLA protein in rice, and stabilizes SLR1. Finally, IPA1 and OsSPL7 increase disease resistance and reduced growth through repressing GA signaling.
The salicylic acid receptor, OsNPR1 physically interact with IPA1 and facilitate the binding of IPA1 on defense-related genes. OsNPR1 enhance the transcriptional activity of IPA1 on both down-regulated genes and up-regulated genes. In the nucleus, IPA1 stabilize OsNPR1 through interfering the interaction between OsNPR1 and OsCullin3a, the E3 ligase for OsNPR1. The mutual enhancement between IPA1 and OsNPR1 boosts rice immunity.
& The molecular mechanism of RNA-directed DNA methylation
We identified the 24-nt siRNA precursors, which range from 25-nt to 50-nt in length. Without four DCLs, the precursors of 24-nt siRNAs could direct DNA methylation at most RdDM loci on whole genome scale. We also demonstrated that four CLASSY genes, encoding chromatin remodeling proteins, is collectively required for Pol IV-RDR2 generating 24-nt siRNAs. In addition, mutation in single or two CLASSY could result in DNA hypermethylation.
Our study found that overexpression of OsGA2ox1, encoding a GA deactivating enzyme, driven by constitutive 35S promoter largely reduces bioactive GA levels and results in dwarfism. The 35S::OsGA2ox1 transgenic rice plants were autonomously silenced and rescued GA levels and plant height. We isolated dozens of five elements mountain (fem) mutants that restored OsGA2ox1 overexpression. Map-based cloning demonstrated that FEM1 encodes OsRDR2, FEM2 encodes a chromatin remodeler (CLSY homologue), FEM3 encodes OsNRPE1b (the largest subunit of RNA polymerase V). Using these fem mutants, we found that RdDM activity is substantially enhanced in reproductive organs and is required for reproductive development. The difference between Pol V-dependent and -independent 24-nt siRNAs is associated with epigenetic modifications (DNA methylation in three contexts, histone modifications).
Main Achievements
Multiple diseases threaten yield production and food safety. Our laboratory focus on rice diseases including bacterial blight, blight leaf streak, and sheath blight. We are dedicated to clone new resistance genes against these diseases, and reveal the underlying mechanism of these genes mediated-immunity. On particular, the trade-off of immunity on yield-related traits is under investigated. Using technology such as molecular marker assistant selection, genome editing and transgene, the disease resistance genes will be applied in rice breeding.
Transgene is the technology to quickly utilize disease resistance genes in crop breeding. Transgenes often be silenced by genomic immunity in rice. The mechanism of gene silencing in Arabidopsis is well demonstrated. In crops, however, the gene silencing machinery is largely unknown. We are cloning the genes that are essential for gene silencing and created new germplasm of suppressing gene silencing.
