Disease relevance of rps2

  • The array was used to compare the responses of wild-type, rps2 and ndr1 mutant plants to infection by a Pseudomonas syringae strain expressing avrRpt2 [1].
 

High impact information on rps2

  • Transgenic RPS2 and rps2 plants that contain the glucocorticoid-inducible avrRpt2 gene will provide a powerful new tool for the genetic, physiological, biochemical, and molecular dissection of an avirulence gene-specified cell death response in both resistant and susceptible plants [2].
  • Growth of P. syringae pv. tomato DC3000 expressing avrRpt2EA was 10-fold higher than that of P. syringae pv. tomato DC3000 in an Arabidopsis rps2 mutant, indicating that avrRpt2EA promotes virulence of P. syringae pv. tomato DC3000 on Arabidopsis similar to P. syringae pv. tomato avrRpt2 [3].
  • In the maize mt genome, two rps2 genes were identified and both are transcribed, although at different levels [4].
  • These experiments show that the wild-type allele at the rps2 locus, RPS2, encodes a component of a signal transduction pathway that responds to a signal generated by avrRpt2 and that RPS2 is required for the elicitation of an HR [5].
