“Zoom-in” view of the only area of the 2-D gels that shows differentially accumulated protein spots when the healthy plant of the susceptible species WVa700 (panel A) was inoculated with the pathogen R. solanacearum (panel B). The spot number is in accordance with the number used in Table 2. The tomato stem cell wall proteome was separated between pH 3–11 (non linear IPG stripes) and in the molecular mass range between 100 and 10 kDa. However, the basic pI side of the 2-D gel containing poorly separated proteins was removed before fixing and staining. All the shown spots regulation was consistently reproduced in three biological replications and is statistically significant (Student’s t test, P ≤ 0.05)
