Abstract
Injection of Red Mexican bean leaves with Pseudomonas phascolicola Race 2 (compatible, 18 h before P. mors-prunorum or P. phaseolicola Race 1 (incompatible), or simultaneous inoculation with compatible and incompatible bacteria (3:1) greatly delayed the appearance of hypersensitive responses. When compatible bacteria were inoculated 12 h or less before incompatible bacteria, or when the ratio of these bacteria was 1:1 or 0.3:1 in simultaneous inoculation, hypersensitive responses did develop. Earlier inoculation with incompatible bacteria delayed the appearance and severity of disease symptoms following later inoculation with compatible bacteria. When selected areas of leaves were inoculated with compatible bacteria, effects on hypersensitive responses were confined to these areas when the whole leaf was inoculated later with incompatible bacteria. Inoculation through the upper leaf surface with incompatible bacteria did not affect susceptible responses when compatible bacteria were inoculated 24 h later through the lower surface. Treatment of leaves with heat-killed bacteria or live bacteria in numbers insufficient to cause hypersensitive responses did not prevent development of these responses following later inoculation with incompatible bacteria. Use of heat-killed bacteria did suppress hypersensitive responses in tobacco leaves. Injection of leaves with cycloheximide (20 p.p.m.) 30 min before inoculation with incompatible bacteria suppressed leakage of electrolytes and browning of tissues associated with hypersensitive responses. Cycloheximide had little effect on leakage of electrolytes from leaves inoculated with compatible bacteria or with the development of susceptible responses. Exposure of leaves to chloroform vapour delayed hypersensitive responses by 24 h; treatment with peroxidase had no effect.
