How can you use “avirulent” in a sentence? Here are some example sentences to help you improve your vocabulary:
The goals of this work were twofold: to use cDNA microarrays to characterize the primary response of intestinal epithelial cells to a well-studied intracellular pathogen, L. monocytogenes , and to try to identify host gene-expression programs which are induced by specific stages of the infection by comparing the wild-type expression profile to that of mutants which are either incapable of intracellular growth and thus avirulent, or which cannot initiate actin polymerization in host cell cytoplasm.
The Pst DC3000 expressing avrRpm1 gene induces hypersensitive cell death in Col-0 plants and was used to infect plants for constructing the avirulent bacterial library.
The sagA/pel mutant of isolate CS101 fails to express β-hemolysin, SpeB, SK or surface M and M-related proteins [ 4 ] . Based on prior studies from our laboratory [ 9 10 ] , we predicted that this isolate would be avirulent in the mouse skin air sac model.
In contrast to SAR induction, induction of PR-1 by avirulent bacteria has been shown to occur in npr1 mutants [ 11 ] . It is, however, reduced in extent and delayed.
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 ] .
