   * It was shown in pepper and tomato lines without //Bs2 //that mutations of catalytic residues in the glycerolphosphodiesterase did not interfere with the ability of the plant to recognize AvrBs2 through the cognate R gene //Bs2//  and trigger disease resistance. This finding suggests that recognition of AvrBs2 is independent of its glycerolphosphodiesterase enzyme activity (Zhao //et al//., 2011).   * It was shown in pepper and tomato lines without //Bs2 //that mutations of catalytic residues in the glycerolphosphodiesterase did not interfere with the ability of the plant to recognize AvrBs2 through the cognate R gene //Bs2//  and trigger disease resistance.
