OsFD4 promotes the rice floral transition via florigen activation complex formation in the shoot apical meristem. OsFD4 promotes the rice floral transition via florigen activation complex formation in the shoot apical meristem

We used mutant analysis, protein–protein interaction assays and DNA affinity purification (DAP) sequencing coupled to in silico prediction of binding syntaxes to study several bZIP proteins that assemble into florigen activation/repressor complexes (FACs/FRCs). Overall design: DAP-seq of OsBZIP42, OsBZIP69, and OsBZIP77
