Abstract
The invention provides methods and compositions for the production of transgenic plants, plant cells, embryos, and seeds that produce plants with floral organs that have increased mass and/or size as compared to wild-type plants. The transgenic plants can be transformed with a genetic construct comprising an ipt gene under the control of an APETAL3 promoter.
Claims12
An isolated nucleic acid molecule comprising a polynucleotide molecule encoding isopentenyl transferase (IPT) operably linked to a polynucleotide molecule that comprises a APETALA3 promoter that drives tissue-specific expression in a floral organ;
- wherein a plant comprising said nucleic acid molecule produces flowers that have an increase in the size of the corolla, tube, stigma, style, and ovary;
- and an increase in mass of the sepal and receptacle, whole flower, petal, ovary, stigma, and style compared to flowers produced by a control plant of the same genetic background.
