Plant galactinol synthase homologs
View Patent ↗Isolated nucleic acid fragments encoding galactinol synthase are disclosed. Recombinant DNA construct(s) for use in altering expression of endogenous genes encoding galactinol synthase are also disclosed.
1. An isolated polynucleotide comprising:
(a) a nucleotide sequence encoding a polypeptide having galactinol synthase activity, wherein the polypeptide has an amino acid sequence of at least 95% identity when compared to SEQ ID NO: 2, or
(b) a fragment of the isolated polynucleotide in (a) that functions to co-suppress endogenous nucleic acid sequences encoding polypeptides having galactinol synthase activity.
2. The polynucleotide of claim 1 , wherein the amino acid sequence of the polypeptide comprises SEQ ID NO:2.
3. The polynucleotide of claim 1 , wherein the nucleotide sequence comprises SEQ ID NO:1.
4. A vector comprising the polynucleotide of claim 1 .
5. A recombinant DNA construct comprising the polynucleotide of claim 1 operably linked to at least one regulatory sequence.
6. A method for transforming a cell, said method comprising transforming a cell with the polynucleotide of claim 1 .
7. A cell comprising the recombinant DNA construct of claim 5 .
8. A method for producing a plant, said method comprising transforming a plant cell with the polynucleotide of claim 1 and regenerating a plant from the transformed plant cell.
9. A plant comprising the recombinant DNA construct of claim 5 .
10. A seed comprising the recombinant DNA construct of claim 5 .
