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.
本发明涉及具有单倍体诱导体生物活性的非转基因植物和转基因植物,优选作物植物,该植物包含多核苷酸,该多核苷酸包含编码中心粒组蛋白H3(CENH3)蛋白的核苷酸序列,其中该多核苷酸包含至少一个导致CENH3蛋白氨基酸序列改变的突变,本发明还涉及该部分的一部分。此外,本发明还提供了产生诱导植物的方法、使用诱导植物产生单倍体和双单倍体植物的方法以及促进细胞质交换的方法。
