Example sentences for: avr

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

  • Therefore, SAR and PR gene expression of npr1 mutant plants were assessed in response to a second avr gene ( avrB ). Markedly different results were obtained.

  • However, induction of SA accumulation by ndr1-1 mutant plants was impaired at early time points to a similar extent in response to bacteria carrying either avr gene [ 4 ] . These results suggested that at least two pathways control SAR and PR-1 gene expression.

  • However, avrRpt2 was shown to differ markedly from the other characterized P. syringae avr genes in the responses it elicited on ndr1 mutant plants [ 4 5 7 ] . The apparent challenge to the hypothesis of co-regulation could have been because of the choice of an atypical avr gene.

  • The Arabidopsis ndr1-1 mutant showed drastically impaired induction of SAR and PR-1 gene expression in response to infection with Pseudomonas syringae bacteria carrying the avirulence ( avr ) gene avrRpt2 [ 4 ] . This mutant is also incapable of showing a hypersensitive response (HR) to these bacteria [ 5 6 ] except at very high levels of inoculum [ 7 ] . The HR is a macroscopic leaf collapse.

  • The high levels of inoculum used in the cited study can only be used without causing "false positive" HRs if a bacterial strain that is not a pathogen of Arabidopsis is used to deliver the avr gene product [ 5 7 ] . When sid2 plants were inoculated with 1 × 10 8mL -1of a nonpathogen strain ( P. syringae pv.
