Six cDNA clones whose corresponding mRNAs accumulate early during the hypersensitive reaction in tobacco leaves have been classified into 2 groups according to their maximum levels of accumulation in an incompatible versus a compatible interaction with Pseudomonas solanacearum. We present evidence that, at least in the first stages of the interaction, tobacco cell suspensions retain the ability to respond differentially to compatible and incompatible isolates of P. solanacearum. In addition, studies on the effect of a fungal elicitor on the accumulation of the mRNAs corresponding to the cDNA clones in cell suspensions indicate that only one group of genes responds to this treatment.
