摘要： The present disclosure provides a modified CenH3 protein that, when present in a plant, allows the plant to be used as a haploid inducer line for plant breeding purposes. Polynucleotides encoding such modified CenH3 proteins, chimeric genes and vectors comprising such polynucleotides, host cells, and plants comprising such polynucleotides, chimeric genes or vectors are also provided. Additionally, methods for making such plants as well as methods for producing haploid or doubled haploid plants using such plants are disclosed.

摘要： It was found that plants comprising modified CENPC protein comprising one or more active mutations which affect the functioning of CENPC protein yet allow plants expressing said modified CENPC protein to be viable, are able to induce haploid offspring after a cross to or with a wild type plant comprising a endogenous CENPC protein. The invention relates to generation of haploid and doubled haploid plants.

摘要： It was found that plants with loss of functional Msi2 protein due to a nucleotide polymorphism resulting in the introduction of a premature stop codon in the Msi2 protein, are able to induce haploid offspring after a cross to or with a wild type plant comprising a functional Msi2 protein. The invention relates to generation of haploid and doubled haploid plants.

摘要： The present invention relates to a method for obtaining rubber from rubber-containing plant material, the method comprising the steps of subjecting a composition comprising rubber-containing plant material and a fermentation culture to conditions allowing anaerobic fermentation, wherein the composition preferably has a water content of less than 95 wt. %. The fermentation preferably does not involve movement of the rubber-containing plant material (or parts thereof), and preferably the fermentation is performed in the absence of oxygen ventilation. Additionally, it is preferred that the fermentation culture is cycled through the composition by percolation. A further step of the method involves obtaining the rubber from the composition.

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： The present invention relates to a method for obtaining Taraxacum plants of considerable size and substantial rubber content, preferably by providing Taraxacum plants having a relatively large genome size and/or having a specific percentage of Taraxacum koksaghyz (TKS) derived genes and a specific percentage of Taraxacum officinale (TO) derived genes; selecting these plants for the presence or absence of certain markers; and subsequently selecting the plants on plant size, and on genome size.
