Differential phenotypes of <i>L. japonicus</i> ecotypes MG-20 and Gifu B-129 against <i>Pto</i>.

<p><b>A</b>. Symptom development following bacterial infiltration in leaves from both ecotypes. Central leaflets were infiltrated using a needleless syringe as described in Materials and Methods. Eventually, lateral leaflets were marked with a black pen just for identification purposes. Pictures were taken immediately before inoculation and after a period of 24, 48 or 72 h. B. Measurement of <i>Pto</i> growth within MG-20 and Gifu B-129 infiltrated leaves. Data points represent the mean ± SD of three replicate experiments. Bacterial levels at 24, 48 and 72 hpi were statistical analyzed and compared against bacterial levels at 0 hpi, ** p<0.01. Black squares, MG-20; white squares, Gifu B-129.
