How can you use “pr-” in a sentence? Here are some example sentences to help you improve your vocabulary:

The HR occurs in response to infection with avirulent bacteria at levels of inoculum that cause a large percentage of leaf cells to undergo programmed cell death (PCD) [ 8 ] . In contrast to results with avrRpt2, P. syringae bacteria carrying the avirulence genes avrB , avrRpm1 , avrPphB or avrRps4 elicit an exaggerated HR relative to that on the wild-type Columbia parent [ 5 7 ] . In a study in which bacteria carrying avrB were chosen as a representative member of this class, in further contrast to results with avrRpt2 , these bacteria were capable of eliciting SAR and PR-1 induction on ndr1-1 mutant plants [ 4 ] .
However, the analogous experiment with PR-5 induction gave the opposite results.
This study could not address the question as to whether the HR-associated pathway alone was sufficient to induce SAR and PR-1 because SA accumulation did occur late in the response.
As the double mutant was susceptible to disease caused by this bacterial strain (data not shown), perhaps this residual gene induction was due to the virulence function of avrRpt2 [ 23 ] . Mutant npr1 plants have previously been shown to be impaired in induction of PR-1 but not PR-5 in response to virulent bacterial pathogen [ 19 ] .
The correlation between ability to elicit the HR and to elicit SAR and PR-1 induction led to the model that the second pathway was caused by signals associated with hypersensitive cell death.
