Abstract: Provided here are methods of using a mutated patatin-like phospholipase IIα (“pPLAIIα,” renamed here MATRILINEAL) to induce haploid induction in plants, cloning a pPLAIIα to induce haploid induction in plants, and genetically engineering a plant to contain a mutated pPLAIIα. 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.

Abstract: Provided are isolated cDNAs comprising a nucleotide sequence having at least 90% identity to SEQ ID NO: 33, SEQ ID NO: 37, SEQ ID NO: 52 or SEQ ID NO: 53. Also provided are expression cassettes; vectors; transgenic plant cells; plants, plant parts, and seeds; isolated polypeptides; amplicons and informative fragments of the presently disclosed nucleic acids; compositions that include amplification primer pairs; methods for producing plants that exhibit HI; methods for identifying the presence or absence of an allele associated with HI in a plant; methods for introgressing Haploid—inducing nucleotide sequences into plants; and methods for selecting parental plants predicted to produce progeny generations with plants that exhibit Haploid Induction trait.

Abstract: The presently disclosed subject matter relates to using a haploid inducing line (whether existing or created) and transforming the haploid line so that it encodes cellular machinery capable of editing genes. The transformed haploid inducing line is used as a parent in a cross between two plants. During pollination, the parental gametes fuse to form an embryo; and the gene editing machinery is also delivered to the embryo at this time. During embryonic development, one set of parental chromosomes are lost, and the gene editing machinery operates on the remaining set of chromosomes. Thus, at least one haploid progeny with edited genes is produced from the cross.
