Title:	MADS gene regulatory sequences for expressing gene products in plant reproductive tissue
Abstract:	Expression cassettes causing specific regulatory control of transgene expression in plants, wherein the expression cassettes include regulatory sequences from the MADS gene family for expression of recombinant gene products in the reproductive tissue of plants for the purpose of generating abiotic stress tolerant plants.

Assignee:	Syngenta Participations AG (Basel, CH)
Application Number:	13/284,091
Patent Claims:	1. An expression cassette for expression of a nucleic acid molecule product in the reproductive tissue of a plant, comprising: a) a promoter, a first exon; a first intron, and a second exon of a plant MADS gene, wherein said promoter, first exon, intron, and second exon are the 5'-regulatory sequence of said expression cassette; wherein said 5'-regulatory sequence has been engineered 1) to include a translational initiation codon at approximately the 3' end of said 5'-regulatory sequence, 2) to eliminate restriction endonuclease sites that hinder manipulation by recombinant DNA methods, and 3) to modify any additional translation initiation codons upstream of said translation initiation codon to be inoperable so that the MADS gene's protein coding sequence is silent, while preserving the length of the 5'-regulatory sequence in the expression cassette; b) a 3'-regulatory sequence of a plant MADS gene; and c) a nucleic acid molecule operably linked to said 5'-regulatory sequence and said 3'-regulatory sequence, wherein the product of the expression of said nucleic acid molecule is targeted to the reproductive tissue of a plant. 2. The expression cassette of claim 1, wherein the product of said nucleic acid molecule when expressed in a plant makes said plant abiotic stress tolerant. 3. The expression cassette of claim 1, wherein when expressed in a plant the product of said nucleic acid molecule increases the sink strength in said reproductive tissue of said plant. 4. The expression cassette of claim 2, wherein said nucleic acid molecule is a sucrose transporter gene. 5. The expression cassette of claim 2, wherein said nucleic acid molecule is an invertase gene. 6. The expression cassette of claim 2, wherein said nucleic acid molecule is a RNA interference molecule directed against an invertase gene. 7. The expression cassette of claim 1, wherein said nucleic acid molecule is a nucleic acid molecule encoding a trehalose-6-phosphate phosphatase protein. 8. The expression cassette of claim 7, wherein said nucleic acid molecule is depicted by SEQ ID NO. 531. 9. The expression cassette of claim 1, wherein said expression cassette is depicted by SEQ ID NO. 532. 10. The expression cassette of claim 1, wherein said expression cassette is depicted by SEQ ID NO. 536, 537, 538, or 539. 11. The expression cassette of claim 2, wherein said nucleic acid molecule is a trehalose metabolism gene. 12. The expression cassette of claim 2, wherein said nucleic acid molecule is a RNA interference molecule directed against a trehalose metabolism gene. 13. A recombinant vector comprising the expression cassette of claim 1. 14. A transgenic plant cell comprising the expression cassette of claim 1. 15. A transgenic plant comprising the transgenic plant cell of claim 14. 16. A transgenic plant according to claim 15, wherein said plant is a monocot plant. 17. A transgenic plant according to claim 15, wherein said plant is a maize plant. 18. A transgenic plant according to claim 15, wherein said plant is a rice plant. 19. Transgenic seed from the transgenic plant of claim 15. 20. The expression cassette of claim 1, comprising a 5'-regulatory sequence selected from the group consisting of SEQ ID NOS. 6, 12, 20, 28, 506, 34, 39, 43, 47, 51, 55, 59, 63, 67, 71, 75, 79, 83, 87, 91, 95, 99, 103, 107, 111, 115, 119, 123, 127, 131, and 526 and a 3'-regulatory sequence selected from the group consisting of SEQ ID NOS. 10, 16, 24, 30, 507, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, 76, 80, 84, 88, 92, 96, 100, 104, 108, 112, 116, 120, 124, 128, 132, and 527.
