Yes. The MCS region of pCAMBIA vectors does'nt have the promoter and terminator. Alternatively, for example if you opt to use pCAMBIA1305.1, you replace the reporter gene (GUS) and instead clone your gene of interest utilizing the available restriction sites viz., NcoI, SpeI on one side and NheI, PmlI on the other side. By this way you don't have to clone the promoter and terminator additionally.

Thanks for the valuable information.

If its pCAMBIA 1302, use any of these sites NcoI, BglII, SpeI, PmlI, Bst EII, That will place your target gene between 35S promoter and nos terminator; Selection of these sites will also decide if GFP will be fused to your target or not.

Thank you all for the kind and prompt reply.

However, my doubt was, if the MCS has to be used, whether the regulatory sequences (Promotor and terminator) are to be cloned compulsorily along with the gene of interest . Because, there must be an eukaryotic expression cassette to express any gene in the plants, which is not there in the MCS.

Yes, in that case you must include an intact gene expression cassette comprising the promoter ---- gene ---- terminator

Thank you.

If you do not make your gene cassette complete (Promoter-Coding seq-Terminator) your gene may not express well.

Yeah. The regulatory components are must.
