NIN and infection: The replacement of PACE within the L. japonicus (Fabales) 3-kb NIN promoter with PACE sequence variants (NINpro::Species abbreviation PACE:NIN) originating from Casuarina glauca (Fagales), Datisca glomerata (Cucurbitales) or Dryas drummondii (Rosales) restored the complete infection process in nin-15 to similar level as NINpro:NIN, demonstrating the functional conservation of PACE from nodulating species across the entire FaFaCuRo clade (Fig. 3c and Extended Data Fig. 9).
