| 摘要 |
The present invention relates to non-transgenic and transgenic plants, preferably crop plants, having biological activity of a haploid inducer and comprising a polynucleotide which comprises a nucleotide sequence encoding a centromer histone H3 (CENH3) protein, wherein the polynucleotide comprises at least one mutation causing an alteration of the amino acid sequence of the CENH3 protein, and to a part of the part. Further, the invention provides methods of generating the inducer plants, methods of generating haploid and double haploid plants using the inducer plants as well as methods of facilitating cytoplasm exchange. |
