摘要： 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.

摘要： Provided are isolated cDNAs. In some embodiments, the isolated cDNA are selected from the group consisting of: (a) a nucleic acid having at least 90% identity to SEQ ID NO: 33, SEQ ID NO: 37, SEQ ID NO: 52 or SEQ ID NO: 53, optionally wherein the percent identity is calculated over the entire length of SEQ ID NO: 33, SEQ ID NO: 37, SEQ ID NO: 52 or SEQ ID NO: 53; (b) a nucleic acid having at least 95% identity over nucleotides 91-1452 of SEQ ID NO: 33; (c) a nucleic acid that is the reverse complement of either of (a) or (b); and (d) a nucleic acid that encodes a polypeptide comprising an amino acid sequence that is at least 95% identical to SEQ ID NO: 54, or SEQ ID NO: 55, or SEQ ID NO: 56, or SEQ ID NO: 57 optionally wherein the percent identity is calculated over the entire length of SEQ ID NO: 54, or SEQ ID NO: 55, or SEQ ID NO: 56, or SEQ ID NO: 57.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.
