Disease relevance of PSPTO_1949

  • Within-species flagellin polymorphism in Xanthomonas campestris pv campestris and its impact on elicitation of Arabidopsis FLAGELLIN SENSING2-dependent defenses [1].
  • We also compared FLARE gene sets and genes induced in basal or gene-for-gene interactions upon different Pseudomonas syringae treatments, and infer that Pseudomonas syringae pv tomato represses the flagellin-initiated defense response [2].
 

High impact information on PSPTO_1949

  • Arabidopsis thaliana FLAGELLIN SENSING2 (FLS2), a transmembrane leucine-rich repeat kinase, confers flagellin responsiveness [1].
  • In addition, the purified phytotoxin coronatine, a known virulence factor of P. syringae, suppresses the flagellin-induced NHO1 transcription [3].
  • Direct expression of DC3000 effectors in protoplasts indicated that at least nine effectors, HopS1, HopAI1, HopAF1, HopT1-1, HopT1-2, HopAA1-1, HopF2, HopC1, and AvrPto, are capable of suppressing the flagellin-induced NHO1 expression [3].
  • However, the importance of flagellin perception for disease resistance has, until now, not been demonstrated [4].
 

Analytical, diagnostic and therapeutic context of PSPTO_1949

  • We surveyed the early transcriptional response of Arabidopsis cell cultures and seedlings within 60 min of treatment with flg22, a peptide corresponding to the most conserved domain of flagellin [2].
  • HrpA was separated from the major contaminant, the flagellin, by gel filtration to a fraction containing HrpA as well as its three N-terminally truncated forms [5].
