Abstract
Official abstract text for this publication.
The present invention concerns an isolated polynucleotide responsible of haploid induction in maize plants and related processes. Additionally, the invention relates to plants that have been genetically transformed with the polynucleotide of the invention. The invention also relates to a process for screening a mutant plant population for enhanced haploid induction by using said isolated polynucleotide. The invention further relates to molecular markers associated with haploid induction in maize plants and their use in quality control for inducer lines.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for isolating a mutant haploid inducer sequence in a plant other than maize comprising: (1) determining the presence in a plant population of a sequence that is orthologous to: (a) a polynucleotide comprising or consisting of SEQ ID NO: or (b) a polypeptide encoded by the polynucleotide of (a); and selecting said sequence as an orthologous sequence if it codes for a polypeptide which is expressed in pollen or a pollen tube of the plant, and which comprises a lipid anchor domain in its C-terminal and N-terminal polypeptide sequence; (2a) screening a mutant plant population, other than maize, to identify a mutant haploid inducer of the orthologous sequence determined in (1); or (2b) generating a mutant, haploid inducer, of the orthologous sequence selected in (1) by using a gene editing method, wherein said mutant haploid inducer of the orthologous sequence codes for a polypeptide which does not comprise a lipid anchor domain in its C-terminal polypeptide sequence; and (3) isolating said mutant haploid inducer sequence. 2. The process according to claim 1 , wherein the orthologous sequence identified in (2a) is a fragment. 3. A plant other than maize having a mutant haploid inducer sequence isolated by the method according to claim 1 . 4. The process according to claim 1 , wherein the plant other than maize is not a cereal.
