Title:	Construct and method for expressing transgenes using a Brassica bidirectional constitutive promoter
Abstract:	Provided are constructs and methods for expressing multiple genes in plant cells and/or plant tissues using a disclosed bidirectional promoter from Brassica napus or Brassica bidirectional constitutive promoter (BBCP). The constructs provided comprise at least one such bi-directional promoter linked to multiple gene expression cassettes, wherein each of the gene expression cassettes comprises at least one transgene. In some embodiments, the constructs and methods provided allow expression of genes between two and twenty.

Patent Claims:	1. A nucleic acid construct for expressing multiple genes in plant cells and/or tissues, comprising, (a) a bi-directional promoter comprising a nucleotide sequence selected from SEQ ID NO: 2 or 3; and (b) two gene expression cassettes on opposite ends of the bi-directional promoter. 2. The nucleic acid construct of claim 1, wherein the bi-directional promoter comprises at least one enhancer. 3. The nucleic acid construct of claim 1, wherein the bi-directional promoter comprises at least one intron. 4. The nucleic acid construct of claim 1, wherein the bi-directional promoter comprises at least one 5' untranslated region. 5. The nucleic acid construct of claim 1, wherein at least one of the gene expression cassettes comprises two or more genes linked via a translation switch. 6. The nucleic acid construct of claim 1, wherein both the gene expression cassettes comprise two or more genes linked via a translation switch. 7. The nucleic acid construct of claim 5, wherein the translation switch is selected from the group consisting of an internal ribosome entry site (IRES), an alternative splicing site, a polynucleotide sequence coding a 2A peptide, a polynucleotide sequence coding a 2A-like peptide, a polynucleotide sequence coding an intein, a polynucleotide sequence coding a protease cleavage site, and combinations thereof. 8. The nucleic acid construct of claim 5, wherein a gene upstream of the translational switch does not comprise a translation stop codon. 9. The nucleic acid construct of claim 1, wherein the nucleic acid construct of comprises at least four transgenes. 10. The nucleic acid construct of claim 1, wherein the nucleic acid construct comprises between three and twenty transgenes. 11. The nucleic acid construct of claim 10, wherein the nucleic acid construct comprises between four and eight transgenes. 12. The nucleic acid construct of claim 1, wherein neither of the gene expression cassettes comprises an EPSPS coding sequence or paralog. 13. A method for generating a transgenic plant comprising transforming a plant cell with the nucleic acid construct of claim 1 and regenerating a transgenic plant comprising said construct from said plant cell. 14. A method for generating a transgenic plant cell, comprising transforming the cell with the nucleic acid construct of claim 1. 15. A plant cell comprising the nucleic acid construct of claim 1. 16. The plant cell of claim 15, wherein the nucleic acid construct is stably transformed into the plant cell. 17. A transgenic plant or seed comprising the nucleic acid construct of claim 1. 18. The transgenic plant or seed of claim 17, wherein the nucleic acid construct is stably transformed into cells of the transgenic plant or seed. 19. The transgenic plant of claim 17, wherein the transgenic plant is a dicotyledonous plant. 20. The transgenic plant of claim 17, wherein the transgenic plant is a monocotyledonous plant. 21. A method for expressing multiple genes in plant cells and/or tissues, comprising introducing into the plant cells and/or tissues the nucleic acid construct of claim 1. 22. The method of claim 21, wherein the plant cells and/or tissues are stably transformed with the nucleic acid construct of claim 1. 23. A binary vector for Agrobacterium-mediated transformation comprising the nucleic acid construct of claim 1. 24. A method for manufacturing transgenic seeds, comprising introducing the nucleic acid construct of claim 1 into a plant or plant cell, regenerating a transgenic plant from said cell, and collecting seeds from said plant, wherein said seeds comprise said nucleic acid construct. 25. The nucleic acid construct of claim 1, wherein the nucleotide sequence is SEQ ID NO: 2. 26. The nucleic acid construct of claim 1, wherein the nucleotide sequence is SEQ ID NO: 3.
