Abstract
Methods and compositions for modulating plant development are provided. Polynucleotide sequences encoding isopentenyl transferase (IPT) polypeptides are provided, as are the amino acid sequences of the encoded polypeptides. The sequences can be used in a variety of methods including modulating root development, modulating floral development, modulating leaf and/or shoot development, modulating senescence, modulating seed size and/or weight and modulating tolerance of plants to abiotic stress. Transformed plants, plant cells, tissues and seed are also provided.
Claims9
A method of modulating cytokinin level in a plant, comprising transforming said plant with a construct comprising a promoter operably linked to a polynucleotide selected from the group consisting of:
- (a) a nucleotide sequence encoding a polypeptide comprising an amino acid sequence having 95% identity to SEQ ID NO:
- 4 or 7, wherein said polypeptide has cytokinin synthesis activity and comprises the consensus sequence of SEQ ID NO:
- 9;
- and
- (b) a nucleotide sequence comprising the coding sequence of SEQ ID NO:
- 3 or 6.
