Embodiment 1
[0043] Embodiment 1, the method for cultivating the transgenic wheat that iron content improves in grain
[0044] 1. Experimental materials
[0045] 1. Construction of pBAC47P vector:
[0046] The pSP72 vector of Promega Company was used as the starting vector, the promoter of wheat high molecular weight glutenin subunit 1Dx5 was inserted between HindIII and Sal I, and the NOS terminator was inserted between Kpn I and EcoR I. The NOS terminator comes from the pBI121 vector of Clontech Company in the United States. The 1Dx5 promoter is derived from the plant expression vector pBPC30.
[0047] The nucleotide sequence of the promoter of wheat high-molecular-weight glutenin subunit 1Dx5 is shown as nucleotides 1-857 at the 5' end of SEQ ID NO:3. The nucleotide sequence of the NOS terminator is shown as nucleotides 1625-1887 at the 5' end of SEQ ID NO:3.
[0048] 2. Jinghua No. 1 is a Beijing-approved wheat variety cultivated by the Crop Institute of Beijing Academy of Agricultur...
