The invention providesplants and seeds thereof that are self-compatible, rapid-cycling and lack inbreeding depression. For instance, the invention provides plants and seeds of theline designated B3. The invention thus relates to plants, seeds and tissue cultures ofplants that are self-compatible, rapid-cycling and lack inbreeding depression, such asline B3, and methods to produce and propagate said plants by crossing such aplant with itself, or anotherplant. The invention further relates to seeds and plants produced by such crossing. Educational materials, such as a kit comprising saidplants are also provided by the invention.

[object Object]

The present invention provides genetic identification and use information about a family of genes, the FLOWERING LOCUS C (FLC) genes, that is part of the regulate the timing of the onset of flowering in plants. This information enables creation of transgenic plants in which the timing of the flowering of the plants has been selectively altered. Since these genes natively act to delay the time of flowering in plants, enhancing activity of the FLC protein delays the timing of flowering initiation while inhibiting the activity of FLC advances the timing of the start of flowering. A representative number of samples of the gene family are described. Members of the gene family are demonstrated to work in other plant species as well.

Alteration of flowering time in plants

The invention provides vernalization-related polypeptides, nucleic acids and methods of using the same for inducibly-conferring epigenetic change on a target gene in plant or non-plant settings.

Vernalization-related molecules and methods for inducibly-conferring epigenetic changes

The present invention discloses the function, the cDNA sequences, and the expressed amino acid sequences of two genes the expression of which reduced bioactive GA levels and the height of a plant. This information enables creation of dwarf transgenic plants or transgenic plants with a specific dwarf organ.

Dwarfism genes and dwarf plants

The present invention provides an FPA polynucleotide sequence which is involved in controlling the flowering time of plants. The present invention also provides a vector incorporating the protein coding sequence, or a portion or homolog thereof, as well as a genetically modified plant. Also disclosed are methods of producing a genetically modified plant in which the flowering time of the plant has been selectively altered, and methods for reducing the activity of FLC mRNA in plants containing the FLC gene.

Floral induction gene

The present invention discloses the function, the cDNA sequences, and the expressed amino acid sequences of two genes the expression of each of which delayed the flower initiation time of a plant. This information enables creation of transgenic plants with altered flower initiation time.

Dominant gene delaying flowering

The identification of senescence-specific promoters from plants is described. Using information from the first senescence-specific promoter, SAG12 from Arabidopsis, other homologous promoters from another plant have been identified. Such promoters may be used to delay senescence in commercially important plants.

Transgenic plants with altered senescence characteristics

A genetic construct comprising an SAG12 promoter sequence operably connected to a protein-coding DNA sequence not natively connected to the promoter sequence is disclosed. Preferably, this SAG12 promoter sequence is the first 602 bp of SEQ ID NO:2 and the protein-coding sequence encodes isopentenyl transferase.
