(2) Expression of NRG1 in A. thaliana(At) confers recognition to HopQ1 and restricts Ptogrowth: HopQ1 and GFP reporters were transiently expressed in 35s:NbNRG1 transgenic At lines using biolistic delivery, and HR was evaluated by quantifying a reduction of the GFP signal resulting from cell death; found a greater reduction in GFP signal in 3/5 NRG1 lines, compared to GUS lines; in these 3 lines, Ptoproliferation was also reduced in infection assays
