- Key message
- Notably, stable transgenic expression of AGO18 confers broad-spectrum virus resistance in rice
- AGO18 is specifically induced by viral infection and required for antiviral immunity
- In this manuscript, we show that Oryza sativa indica Argonaute protein AGO18 is required for male gametophyte development likely to through a small RNA-mediated mechanism
- Although expression of rice AGO18 in specific stages of male gametogenesis has been documented, its major functions in plant development remain poorly understood
- Here, we show that Oryza sativa indica AGO18 is involved in male gametophyte development
- Our results indicate a distinct role for rice AGO18 in male fertility
- Mechanistically, the JA-responsive transcription factor JAMYB directly binds to the AGO18 promoter to activate AGO18 transcription
- Connection
- AGO18~OsAGO18, miR528, Jasmonate Signaling Enhances RNA Silencing and Antiviral Defense in Rice., Here, we show that jasmonate (JA) signaling transcriptionally activates Argonaute 18 (AGO18), a core RNA silencing component that promotes rice antiviral defense through sequestering miR168 and miR528, which repress key antiviral defense proteins
- AGO18~OsAGO18, miR168, Jasmonate Signaling Enhances RNA Silencing and Antiviral Defense in Rice., Here, we show that jasmonate (JA) signaling transcriptionally activates Argonaute 18 (AGO18), a core RNA silencing component that promotes rice antiviral defense through sequestering miR168 and miR528, which repress key antiviral defense proteins
- AGO18~OsAGO18, JAmyb~OsJAmyb~OsMYB21, Jasmonate Signaling Enhances RNA Silencing and Antiviral Defense in Rice., Mechanistically, the JA-responsive transcription factor JAMYB directly binds to the AGO18 promoter to activate AGO18 transcription
- AGO18~OsAGO18, OsMIR168a, CRISPR-Cas9 mediated OsMIR168a knockout reveals its pleiotropy in rice., Intriguingly, OsAGO18, a member of a new AGO clade that is conserved in monocots, was confirmed to be a target of OsMIR168a not only by informatic prediction but also by expression analysis and a cell-based cleavage assay in the OsMIR168a mutants
- AGO18~OsAGO18, OsMIR168a, CRISPR-Cas9 mediated OsMIR168a knockout reveals its pleiotropy in rice., Many protein-coding genes and miRNAs showed differential expression in the OsMIR168a mutants, suggesting OsMIR168a exerts a major transcriptional regulatory role, likely through its potential target genes such as OsAGO1s and OsAGO18
