Other claims from this paper (11)
- Intervention effect Exogenous ABA enhanced basal resistance of rice against Cochliobolus miyabeanus relative to control plants.
- Mechanism ABA-induced resistance restricts fungal progression in the rice mesophyll.
- Mechanism ABA-induced resistance does not rely on boosted expression of salicylic acid-, jasmonic acid- or callose-dependent resistance mechanisms.
- Mechanism ABA-induced resistance requires a functional Galpha-protein in rice.
- Mechanism ABA steers its positive effect on rice brown spot resistance through antagonistic cross talk with ethylene signalling.
- Intervention effect Genetic disruption of ET signalling makes rice less vulnerable to Cochliobolus miyabeanus attack.
- Intervention effect Genetic disruption of ET signalling gives rice a level of resistance similar to ABA-treated wild-type plants.
- Intervention effect ABA treatment alleviates pathogen-induced activation of the ET reporter gene EBP89 in rice.
- Intervention effect Knockdown of OsMPK5 derepresses pathogen-triggered EBP89 transcription in rice.
- Intervention effect Knockdown of OsMPK5 compromises ABA-induced resistance in rice.
- Mechanism ABA enhances rice resistance to Cochliobolus miyabeanus at least in part by suppressing pathogen-induced ET action in an OsMPK5-dependent manner (model).
