# − unless stated differently: with -3xFLAG (*) untagged (**), or −YFP _N (***) tagged construct.

Indicated constructs were expressed alone or co-expressed with either MtNFP or MtLYK3 in Nicotiana leaves, and the infiltrated regions were marked. Macroscopic symptoms of cell death were scored 48 hai: only infiltrations that resulted in confluent death of (nearly) the entire infiltrated region were scored and are presented as a fraction of total infiltrations performed.
