Abstract
In one aspect, the present invention provides an expression cassette comprising a promoter operably linked to a nucleic acid molecule of interest, which is operably linked to a terminator, further comprising a heterologous intron that enhances expression of the nucleic acid molecule of interest, wherein the heterologous intron is selected from the group comprised of SEQUENCE ID NO. 1 (iZm10430-02), SEQUENCE ID NO. 2 (iZm10430-01) SEQUENCE ID NO. 3 (iZm008975-01), SEQUENCE ID NO. 4 (iZm005854-01), SEQUENCE ID NO. 5 (iZm010719-01), and SEQUENCE ID NO. 6 (iZm007840-01). In another aspect, the present invention provides an expression cassette comprising a promoter operably linked to a nucleic acid molecule of interest, which is operably linked to a heterologous terminator that enhances expression of the nucleic acid molecule of interest, wherein the heterologous terminator is selected from the group of SEQUENCE ID NO. 7 (tZmHSP70-01), SEQUENCE ID NO. 8 (tZmUbi158-01), SEQUENCE ID NO. 9 (tZmUbi1-01), SEQUENCE ID NO. 10 (tZmUbi361-01).
