High impact information on PDF1

  • The GUS expression in transgenic plants disappeared when a mutation that abolishes binding of ATML1 was introduced into the PDF1 l1 box sequence of the construct [1].
  • The Arabidopsis thaliana PROTODERMAL FACTOR1 (PDF1) gene encoding a putative extracellular proline-rich protein is exclusively expressed in the L1 layer of shoot apices and the protoderm of organ primordia [1].
  • Our analysis revealed that the minimum region necessary to confer L1-specific expression of PDF1 is confined within a 260-bp fragment upstream of the transcription start site [1].
  • Unlike the wild type, dnd2 plants responding to virulent and avirulent P. syringae exhibited elevated expression of both salicylate-dependent PR-1 and jasmonate and ethylene-dependent PDF1 [2].
  • In this report, we isolated and characterized a novel recessive mutant, cex1, conferring constitutive JA-responsive phenotypes including JA-inhibitory growth and constitutive expression of JA-regulated AtVSP, Thi2.1 and PDF1 [3].
 

Biological context of PDF1

 

Analytical, diagnostic and therapeutic context of PDF1

  • In situ hybridization revealed that the expression of PDF1 is exclusively limited to the L1 layer of vegetative, inflorescence and floral meristems and to the protoderm of organ primordia [4].
