Other claims from this paper (6)
- Mechanism AvrM14 homodimerization promoted biologically relevant mRNA cap cleavage in vitro.
- Observation Related Melampsora effectors retained mRNA cap cleavage activity.
- Intervention effect Wild-type AvrM14 expression in plants suppressed immune-related reactive oxygen species relative to catalytically dead AvrM14.
- Intervention effect Wild-type AvrM14 expression changed the abundance of circadian-rhythm-associated transcripts relative to inactive AvrM14.
- Intervention effect Wild-type AvrM14 reduced M1-triggered hypersensitive cell death relative to inactive AvrM14.
- Mechanism The authors infer that fungal Nudix effectors with mRNA-decapping activity can interfere with plant immunity.
