  • INCREASING PLANT TRANSFORMABILITY BY CYTOTYPE TRANSFER
    Publication number: 20220174901
    Abstract: A method of altering or transferring the cytotype of a plant line. In particular, transferring the cytotype of a transformation-recalcitrant plant line, e.g., a transformation-recalcitrant maize line, from a transformation-recalcitrant cytotype to a transformable cytotype so that the line becomes transformable while preserving its nuclear genome. The newly-transformable line may be produced using methods including backcrossing and/or haploid induction.

  • HAPLOID INDUCTION COMPOSITIONS AND METHODS FOR USE THEREFOR
    Publication number: 20180332790
    Abstract: Provided here are methods of using a mutated patatin-like phospholipase II? (“pPLAII?,” renamed here MATRILINEAL) to induce haploid induction in plants, cloning a pPLAII? to induce haploid induction in plants, and genetically engineering a plant to contain a mutated pPLAII?. Also provided are methods of applying topical and spray chemicals, lipids, and RNAi molecules to plants during pollination in order to induce haploid production. Further provided are methods of chemically treating plants during pollination to induce haploids while also reducing embryo abortion and increasing seed set.
