摘要:
The present invention is directed toward rice lines containing mutant allele ROXY that exhibit non-transgenic resistance to the herbicide oxyfluorfen. The invention relates to the seeds, plants and plant parts of rice plants containing mutant allele ROXY and to methods for producing a rice plant by crossing rice plants containing mutant allele ROXY with itself or another rice cultivar. The invention further relates to methods for producing a rice plant containing mutant allele ROXY containing in its genetic material one or more transgenes and to the transgenic rice plants and plant parts produced by those methods. This invention also relates to methods for producing other rice cultivars, lines or plant parts derived from rice plants containing mutant allele ROXY and to the rice plants, varieties, and their parts derived from the use of those methods. The invention further relates to transferring mutant allele ROXY to different genetic backgrounds.
摘要:
The present invention relates generally to the fields of genetic engineering and plant molecular biology. Specifically, the invention concerns nucleic acids and polypeptides which confer fungal disease resistance in plants, in particular, resistance to Septoria tritici blotch (STB) disease. Accordingly, the invention relates to isolated nucleic acids and polypeptides which are capable of conferring resistance to the STB disease and the use thereof in generating and identifying STB resistant plants. The invention also encompasses expression vectors comprising said polynucleotides and plants exhibiting resistance to STB disease. The nucleic acids, polypeptides, expression vectors, plants and methods of the present invention may usefully find application in agricultural biotechnology.

The present invention discloses novel DNA construct composition to provide strain non-specific and/or race non-specific broad spectrum tolerance against phytopathogen in host plant. The DNA construct composition comprises ofat least one novel RNAi construct, at least one promoter and at least one transcriptional terminator so designed to produce RNAi gene construct to down-regulate pathogen specific gene target by way of RNAi mediated gene silencing and consequently inhibiting growth of phytopathogen. The RNAi gene constructs are designed for both single gene targets and multi-gene targets. This invention also discloses method of preparing novel DNA construct and the method to control phytopathogens.

The present invention relates to the field of lettuce breeding, in particular to Quantitative Trait Loci for resistance against the lettuce aphid Nasonovia ribisnigri biotype Nr: 1 and to cultivated lettuce comprising one or more of these Quantitative Trait Loci.
摘要:
The invention relates to a new gene that produces a protein which is capable of inferring oomycete resistance, more preferably resistance to Phytophthora infestans when expressed in a plant, wherein said nucleotide sequence encodes a protein that is encoded by the protein produced by the nucleotide sequence of Fig.10 or the protein depicted in Fig. 11 or a nucleotide sequence that codes for a protein that has an identity of at least 95% with said protein produced by the nucleotide sequence of Fig. 10 or the protein depicted in Fig. 11. The invention also relates to a method for providing at least partial resistance or increasing resistance in a plant against an oomycete infection comprising providing a plant or a part thereof with a nucleotide sequence as indicated above or a functional fragment thereof, preferably wherein said plant is a plant from the Solanaceae family, more preferably Solanum tuberosum .
摘要:
One aspect of the present invention relates to a nucleic acid construct that includes a nucleic acid molecule that encodes FLAGELLIN-SENSING 3 ("FLS3") protein; a 5' heterologous DNA promoter sequence; and a 3 ' terminator sequence, where the nucleic acid molecule, the DNA promoter sequence, and the terminator sequence are operatively coupled to permit transcription of the nucleic acid molecule. The present invention also relates to a method of imparting disease resistance to a plant. This method involves transforming a plant or a plant seed with a nucleic acid molecule that increases expression of an FLS3 protein, where said transforming is effective in imparting disease resistance to the transformed plant or to a transgenic plant produced from the transformed plant seed. The present invention also relates to methods of expressing a nucleic acid molecule in a plant, identifying a candidate plant suitable for breeding that displays enhanced disease resistance, and enhancing efficiency of transformation of a plant by Agrobacterium .
摘要:
The present invention is related to a method for the transformation of sugar beet protoplasts comprising the steps of: – obtaining protoplasts from stomatal guard cells isolated from a sugar beet plant, - transforming the protoplasts with a nucleic acid construct comprising a nucleotide sequence of interest and a selection marker sequence, - applying to an in vitro culture of said protoplasts, one or more ALS inhibitors at a concentration that is lethal to the in vitro culture of the protoplasts and - regenerating sugar beet plants from the surviving protoplasts having integrated the nucleic acid construct comprising the sequence of interest and the selection marker sequence, wherein the selectionmarker sequence is the mutated BvALS113 sequence carrying in its sequence a mutation at amino acid 113 position from Alanine to Tyrosine.
摘要:
The present invention relates to Brassica sequences comprising pod-preferential promoter activity. Provided are recombinant genes comprising the pod-preferential promoter operably linked to a heterologous nucleic acid sequence, and cells and plants comprising the recombinant gene. The promoters can be used to alter gene expression specifically in the pods and to alter seed yield, seed quality, abiotic stress tolerance, or biotic stress tolerance.
