Other claims from this paper (9)
- Intervention effect Exogenous ABA compromised rice resistance to compatible M. grisea strains.
- Intervention effect ABA suppressed transcriptional upregulation of WRKY45 induced by SA, benzothiadiazole or blast infection.
- Intervention effect ABA suppressed transcriptional upregulation of OsNPR1 induced by SA, benzothiadiazole or blast infection.
- Intervention effect OsNPR1 overexpression largely negated ABA-enhanced blast susceptibility.
- Observation ABA-responsive genes were induced reciprocally to WRKY45 and OsPR1b in compatible blast interaction, but only marginally in incompatible interaction.
- Observation ABA was detected in M. grisea hyphae and conidia and in culture media.
- Mechanism The authors suggest that fungal ABA could trigger host ABA signaling at infection sites.
- Mechanism The authors infer ABA acts upstream of WRKY45 and OsNPR1 in rice SA signaling.
- Mechanism The authors suggest that the SA–ABA signaling balance determines rice–M. grisea interaction outcomes.
