| Resumo: |
An in vitro system for studying the resistance response of cotton (Gossypium hirsutum L.) to Xanthomonas campestris pv. malvacearum was investigated. Cell suspension cultures, established from hypocotyl-derived callus of cotton cultivar 101-102B, were treated with bacterial extracellular polysaccharides (EPS) extracted from the incompatible race 18 of X. campestris pv. malvacearum. EPS at 600 mug/mL caused pronounced darkening of the suspension cultures, as indicative of cell death, 48 hours after incubation. Protein electrophoresis analysis of the time course of EPS-treated cells showed differential accumulation of several protein bands after 12-24 hours. The time course of protein accumulation and cell death was consistent with an elicitor-mediated hypersensitive response.
