comments:
  - Overexpression of STF3 increased nodulation, RNAi knockdown decreased nodulation.
  - STF3 is induced by the blue light activated transcription factor CRY1 and expressed mainly in leaves.
  - The protein product of STF3 migrates from shoots to roots.
  - After migration, it is phosphorylated by calcium/calmodulin dependent protein kinase (CCaMK), which is activated by rhizobial infection.
  - Phosphorylation causes STF3 and FT2a to form a complex.
phenotype_synopsis: STF3 promotes nodulation by inducing expression of nodule signalling pathway 1 (NSP1), nodule inception (NIN), and nuclear factor Y (NFY) genes.

comments:
  - Overexpression of FT2a increased nodulation while RNAi knockdown decreased nodulation.
  - FT2a is induced by the transcription factors GmCRY1 and CONSTANS.
  - It is mainly expressed in leaves and migrates from shoots to roots.
  - In the shoots, the product of FT2a forms a complex with the phosphorylated product of STF3.
phenotype_synopsis: FT2a is known for stimulating flowering but it also positivley regulates nodulation.
