摘要： The present inventions relate to a breeding system for the production of polyploid potato seeds, plants, or plant parts where cycles of meiosis, syngamy, and selection are used for interpopulation improvement of progenitor lines, and sexual polyploidization occurs during hybrid production by inducing clonal gamete formation in the parents that are to be crossed. Reciprocal recurrent selection can be used to inform selection of candidate potato lines that are either advanced to a gene editing or genetic modification system or crossed and selected to induce clonal gamete formation by arresting meiotic recombination and chromosome reduction. Crosses of parent plants bearing clonal gametes are planned and executed based upon predicted heterotic performance at the polyploid level. The final product is a homogeneous population of hybrid polyploid potato seed, or derivative thereof, bearing both parents' complete nuclear genomes. In some instances, the method is used to generate seedless plants.

摘要： Compositions and methods are capable of modulating male fertility in a plant. Compositions comprise polynucleotides and polypeptides, and fragments and variants thereof, which modulate male fertility. Expression cassettes comprise a male-fertility polynucleotide, or fragment or variant thereof, operably linked to a promoter, wherein expression of the polynucleotide modulates the male fertility of a plant. Regulatory sequences drive expression in a male-tissue-preferred manner and may be targets to downregulate an operably-linked gene. Mutations that induce nuclear recessive male sterility in subsequent selfing and crossing of wheat lines containing the mutations may be tracked. Male-sterile plants may be maintained by crossing with a maintainer plant. Hybrids can be produced using the male-sterile plants.

摘要： The invention provides a method to produce a mutant gene, wherein said gen comprises a modified promoter and wherein said gene is capable of inducing the parthenogenesis phenotype to a plant. The invention further provides said mutant gene, isolated nucleic acid molecule, construct or vector comprising the same. Also, the invention provides for a method to produce a parthenogenetic plant comprising the mutant gene, and the parthenogenetic plant thus obtained.

摘要： Disclosed is a method for breeding self-compatible potatoes, including the following steps: (1) selecting a self-compatible potato variety material and referring to it as PG6359, and cloning the S-RNase gene of PG6359 through the transcriptome sequencing method; and (2) obtaining two full-length sequences of the S-RNase gene from the cloned S-RNase gene in step (1) and referring to them as Ss11 and Ss12 respectively, and after carrying out an artificial self-pollination for the variety material PG6359, selecting the variety material having the genotype of Ss11Ss11 from the offspring as the female parent, and selecting a self-incompatible material as the male parent, and then obtaining a self-compatible F1 generation by hybridization. The invention overcomes the self-incompatibility of diploid potatoes, and does not require the introduction of any wild potato gene fragments, thereby avoiding linkage drag, and providing a basis for the rapid creation of a diploid potato inbred line.

摘要： Non-transgenic and transgenic plants, preferably crop plants, comprising at least one mutation of the KINTEOCHORE NULL2 (KNL2) protein, especially a mutation causing a substitution of an amino acid within the KNL2 protein, preferably within the C-terminal region of the KNL2 protein, which preferably have the biological activity of a haploid inducer. Further are methods of generating plants and haploid and double haploid plants obtainable by crossing non-transgenic and transgenic plants with wildtype plants as well as methods of facilitating cytoplasm exchange.
