The present invention provides compositions and methods for producing a transgenic plant that exhibits altered characteristics resulting from over expression or under expression of a novel polypeptide PtM3 or its homolog PtM4. The altered characteristics resulting from over-expression include at least one of the ability to convert axillary meristem to floral meristem; to accelerate flowering i.e., early flowering; to increase fruit production; to increase nut production; to increase seed output; to increase branching; to increase flower production; to increase fruit yield; to increase flower yield and a combination thereof. The altered characteristics resulting from suppressed expression include at least one of complete sterility; partial sterility (sterility of only one sex of a bisexual plant); reduced pollen production; decreased flowering; increased biomass and combinations thereof. Furthermore, once the transgenic plant is sterile, additional exogenous sequences may be incorporated into the sterile plant genome, resulting in other desired plant characteristics. Related promoter, gene constructs, methods, antibodies and kits are also provided.

This invention relates to plants having modified reproductive capacity. In particular, it relates to a plant reproductive tissue specific promoter, the PrAG1 promoter isolated from, and its use in promoting transcription/expression of associated sequences in plant reproductive tissue, including for the purpose of producing plants which have diminished reproductive capacity or which are sterile.

Plants having modified reproductive capacity

An Agrobacterium-mediated transformation and regeneration method for plants including a transformation method to produce transgenic plants with an altered lignin composition.

Genetic transformation and regeneration of plants

The invention relates to genetically engineering the wood color of woody plants by incorporation of the lignin pathway gene O-methyltransferase into the genome of the plants.
