Model representing proposed mechanism of action for ZmGos2-zmm28 in maize. Distinct ZMM28 protein complexes (in blue) (Fig. 4A) interact with direct target gene promoters (in gray) (Fig. 4B) to regulate transcription, with downstream impacts on biochemical and physiological processes including photosynthesis (in green), nitrogen assimilation (in yellow), and growth regulating hormone reception (in coral) leading to enhanced plant growth and increased grain yield. Question mark represents unidentified transgenic ZMM28 protein–protein interaction partners.
