Abstract
IN the host tissues infected by various plant pathogens, including viruses, bacteria and fungi, as a rule starch accumulates around the infection area1–3. By contrast, the toxin-induced chlorotic halo formed in White Burley tobacco leaves infected by Pseudomonas tabaci (Wolf and Foster) Stevens fails to show any starch reaction (Fig. 1). The low starch content of the affected area was also shown by quantitative chemical determination4 (Table 1). The assays were made 7 days after needle inoculation.
