Abstract
This invention is directed to methods of inducing apomixis in a sexual eukaryote or inducing sexual reproduction in an apomictic eukaryote. More particularly, this invention provides methods of switching from meiosis to apomeiosis and from syngamy to parthenogenesis in a plant. The invention also provides methods of producing an apomictic eukaryote from a sexual eukaryote and a sexual eukaryote from an apomictic eukaryote.
Claims20
A method of inducing apomixis in a sexual eukaryote or sexual reproduction in an apomictic eukaryote, comprising increasing or decreasing glucose or sucrose signaling, osmotic stress, oxidative stress, perceived oxidative stress, or a combination thereof in a female germline cell and/or a female germline-associated tissue in the sexual eukaryote or apomictic eukaryote, wherein apomixis comprises apomeiosis and parthenogenesis and sexual reproduction comprises meiosis and syngamy.
A sexual eukaryote that is induced to reproduce apomictically by inducing apomeiosis, parthenogenesis, or both in the sexual eukaryote by increasing glucose or sucrose signaling, decreasing osmotic stress, decreasing oxidative stress, decreasing perceived oxidative stress, or a combination thereof.
An apomictic eukaryote produced from a sexual eukaryote by decreasing SnRK activity by disrupting an endogenous SnRK gene in the sexual eukaryote.
