The present invention relates generally to the field of recombinant fatty acid synthesis, particularly in transgenic plants. The application describes genes involved in fatty acid synthesis and provides methods and vectors for the manipulation of fatty acid composition of plant oils. In particular, the invention provides constructs for achieving the integration of multiple heterologous genes involved in fatty acid synthesis into the plant genome, such that the resulting plants produce altered levels of polyunsaturated fatty acids. Also described are methods for enhancing the expression of fatty acid biosynthesis enzymes by co-expressing a silencing suppressor within the plant storage organ.

The present invention relates to methods of synthesizing long-chain polyunsaturated fatty acids, especially eicosapentaenoic acid, docosapentaenoic acid and docosahexaenoic acid, in recombinant cells such as yeast or plant cells. Also provided are recombinant cells or plants which produce long-chain polyunsaturated fatty acids. Furthermore, the present invention relates to a group of new enzymes which possess desaturase or elongase activity that can be used in methods of synthesizing long-chain polyunsaturated fatty acids. In particular, the present invention provides ω3 destaurases, Δ5 elongases and Δ6 desaturases with novel activities. Also provided are methods and DNA constructs for transiently and/or stably transforming cells, particularly plant cells, with multiple genes.

The present invention provides a new plant gene-rice high temperature resistance 1 gene (Rice High Temperature Resistance 1, HTR1) and encoded protein thereof. Also disclosed is the use of the high temperature resistance gene, especially for the enhancement of high-temperature resistance of plants in plant variety improvement and cross breeding.

The problem to be solved by this invention is to provide a method of gene introduction for a genus Sorghum plant and a method for producing a transformed genus Sorghum plant with a higher efficiency than the conventionally known Agrobacterium method. This invention provides a gene introduction method of a genus Sorghum plant characterized by using a medium with an increased concentration of a nitrogen source and/or an increased concentration of inorganic ions selected from magnesium ion, potassium ion, calcium ion and sodium ion, in a step of preparing a plant tissue material of a genus Sorghum plant, a step of inoculation with Agrobacterium and/or a co-cultivation step. This invention also provides a method for producing a transformed plant using the gene introduction method of this invention.

Provided herein are methods for increasing plant cell transformation efficiency. These methods include exposing the plant cells to a liquid medium containing a surfactant. Following exposure to the surfactant-containing medium, the cells can become more amenable to transformation and may be genetically transformed using methods known in the art. Exposure of the cells to the surfactant-containing medium prior to transformation can increase plant transformation efficiency when compared to transformation efficiency of cells not exposed to the surfactant-containing medium.

Improved methods and means are provided to modify in a targeted manner the genome of a plant cell or plant at a predefined site via bacterial transformation.

The present invention provides methods for the transformation of viable explants from wheat seeds to permit production of transgenic wheat plants. The present invention also relates to methods for producing such explants and related embodiments.

The present invention belongs to the field of plant genetic engineering. Specifically, the invention relates to a method for base editing in plants. More particularly, the invention relates to a method for performing efficient base editing to a target sequence in the genome of a plant (such as a crop plant) by a Cas9-cytidine deaminase fusion protein, as well as plants produced through said method and progenies thereof.

A method of modifying a glycosylation pattern of a polypeptide-of-interest in a plant or plant cell is provided. The method comprising expressing in a plant or plant cell transformed to express at least one glycosidase in a subcellular compartment, a nucleic acid sequence encoding the polypeptide-of-interest, such that the at least one glycosidase and the polypeptide-of-interest are co-localized to the subcellular compartment of the plant or plant cell, thereby modifying the glycosylation pattern of the polypeptide-of-interest in the plant or plant cell.
