Several NAM, ATAF, and CUC (NAC), myeloblastosi (MYB), teosinte branched 1, cycloidea and PCF (TCP), Homeodomain leucine zipper (HD-ZIP) and Basic helix-loop-helix (bHLH) transcription factors accumulated to their highest levels during the transition from the CP to the DP infection stage, the stages during which secondary cell walls are being established and when light-mediated developmental progression is perhaps strongest. Here, STAC3 is linked to infection.
