Abstract

Provided herein are regulatory elements, such as promoters and terminators, derived or obtained from various Glycine species. Such regulatory elements are useful for expression cassettes for plants, such as soybean. Such expression cassettes generally contain a promoter and terminator sequence to control expression of each coding sequence. For certain traits, such as insect resistance and herbicide tolerance, it may be desirable to use promoters and terminators with medium to high constitutive expression.

First claim

What is claimed is:

1 . An expression cassette comprising a nucleotide sequence having at least 99% identity with one or more of SEQ ID NO: 4 wherein the nucleotide sequence is operably linked to a heterologous nucleotide sequence.

2 . An expression cassette comprising a first nucleotide sequence having at least 99% identity with one or more of SEQ ID: NO: 4 and a second nucleotide sequence having at least 99% identity with one or more of SEQ ID NO: 10, wherein the first and/or second nucleotide sequence are operably linked to a heterologous nucleotide sequence.

3 . The expression cassette of claim 1 , wherein the heterologous nucleotide sequence is a nucleic acid of interest that encodes an RNA or protein of interest.

4 . The expression cassette of claim 3 , wherein the RNA or protein of interest is capable of conferring upon a plant a desired characteristic selected from the group consisting of antibiotic resistance, virus resistance, insect resistance, disease resistance, resistance to other pests, herbicide tolerance, improved nutritional value, improved performance in an industrial process, or altered reproductive capability.

5 . The expression cassette of claim 1 , wherein the heterologous nucleotide sequence encodes a selectable marker or wherein the expression cassette further comprises a selectable marker.

6 . A vector comprising the expression cassette of claim 1 .

7 . The vector of claim 6 , wherein the vector is a plasmid, virus, or Agrobacterium.

8 . A plant cell comprising the expression cassette of claim 1 or vector of claim 6 .

9 . The plant cell of claim 8 , wherein the plant cell is a dicot cell.

10 . The plant cell of claim 9 , wherein the plant cell is a Glycine max cell.

11 . A transgenic plant comprising the plant cell of claim 8 .

12 . The transgenic plant of claim 11 , wherein the plant is a dicot.

13 . The transgenic plant of claim 12 , wherein the plant is a Glycine max plant.

14 . A seed from the transgenic plant of claim 11 .

15 . A method, comprising introducing the expression cassette of claim 1 or vector of claim 7 into a plant or plant cell.

16 . The method of claim 15 , further comprising placing the plant or plant cell under conditions whereby an RNA or protein of interest and/or a selectable marker is expressed from the expression cassette or vector.

17 . The method of claim 15 , further comprising crossing the plant to a second plant or self-crossing the plant to produce a progeny plant.

18 . A transgenic plant produced by the method of claim 15 , or a plant part thereof, wherein the plant part comprises a nucleotide sequence having at least 99% identity with one or more of SEQ ID NO: 4 wherein the nucleotide sequence is operably linked to a heterologous nucleotide sequence.

19 . The transgenic plant, or part thereof, of claim 18 , wherein the plant is a dicot, optionally wherein the plant is a Glycine max plant.
