Abstract excerpt

α-Zeins, the major maize endosperm storage proteins, are transcriptionally regulated by Opaque2 (O2) and prolamin-box-binding factor 1 (PBF1), with Opaque11 (O11) functioning upstream of them. However, whether O11 directly binds to α-zein genes and its regulatory interactions with O2 and PBF1 remain unclear. Using the small-kernel mutant sw1, which exhibits decreased 19-kDa and increased 22-kDa α-zein, we...
