  • Publication number: 20240188502
    Abstract: The present disclosure provides novel methods and compositions for the maturation and regeneration of plantlets from microspore-derived embryos. The compositions provided herein include a liquid maturation composition comprising a first plant hormone and about 430 mM to about 880 mM of a monosaccharide solute, a disaccharide solute, or a polysaccharide solute. The methods provided herein include the steps of contacting a microspore-derived embryo with a liquid maturation medium for a time period sufficient to produce a matured microspore-derived embryo, transferring the matured microspore-derived embryo to a substrate, and regenerating the plantlet from the matured microspore-derived embryo.

  • Publication number: 20230329166
    Abstract: The invention provides novel methods for liquid-mediated delivery of pollen grains to enclosed stigmas in recipient female flowers. For example, methods for liquid-mediated pollination are provided. The methods provided include collecting pollen from a donor plant, suspending the collected pollen in a liquid solution, and introducing said solution to an enclosed stigma of a recipient flower bud on a recipient plant, thereby pollinating the flower with the pollen from the donor plant.

  • Publication number: 20230157233
    Abstract: The invention provides novel methods for microspore embryogenesis and the production of doubled haploid embryos. For example, the methods provided include obtaining a plurality of flower buds from a donor plant, determining the developmental stage of microspores comprised within said flower buds, selecting flower buds comprising microspores at a desired developmental stage, treating said flower buds, isolating microspores from said flower buds, and culturing said microspores in induction medium or treating said isolated microspores with a chromosome doubling agent.
