Figure 9. The CaMV 35S promoter drives expression of CFP or MINI3:CFP in transient bombardment experiments.

Figure 9

CFP signals in seeds bombarded without DNA (A) and with 35::CFP (B) or 35S::MINI3:CFP (C) construct. (D) A model depicting the function of SHB1 in MINI3 and IKU2 expression. SHB1 is likely recruited to the MINI3 and IKU2 promoters by MINI3, which specifically recognizes particular W-box sequences in these promoters. SHB1 or SHB1 together with other proteins activates expression from the MINI3, IKU2, and/or other target gene promoters required for endosperm proliferation and seed cavity enlargement.
