Abstract
The present invention provides a genetically modified plant and a method for producing such a plant characterized as having modulated flower meristem development. As an illustrative example, the invention provides genetically modified tobacco and aspen plants characterized as having early floral meristem development and comprising a structural gene encoding the LEAFY protein in its genome.
Claims28
A genetically modified plant having in its genome a heterologous nucleic acid sequence encoding a flower meristem identity protein selected from the group consisting of LEAFY, APETALA1 and a combination thereof, wherein said plant is characterized as having accelerated flower meristem development.
A seed which germinates into a plant having in its genome a heterologous nucleic acid sequence wherein said sequence encodes a flower meristem identity protein selected from the group consisting of LEAFY, APETALA1 and a combination thereof, and wherein said seed is capable of germinating into a plant having accelerated flower meristem development.
A vector comprising a nucleic acid sequence comprising at least one structural gene encoding a flower meristem identity protein selected from the group consisting of LEAFY APETALA1, and a combination thereof, that accelerates flower meristem development, operably associated with a promoter.
A method of producing a genetically modified plant characterized as having early flower meristem development, said method comprising:
- contacting a plant cell with a vector comprising a nucleic acid sequence comprising a structural gene encoding a flower meristem identify protein selected from the group consisting of LEAFY, APETALA1 and a combination thereof for modulated flower meristem development, said gene operably associated with a promoter, to obtain a transformed plant cell;
- producing a plant from said transformed plant cells;
- and
- selecting a plant exhibiting said early flower meristem development.
