Isolated polynucleotides and polypeptides encoded thereby are described, together with the use of those products for making transgenic plants with increased tolerance to abiotic stress (e.g., high or low temperature, drought, flood).

Insecticidal toxins described herein are fused toxin peptides made up of a targeting domain fused to a toxin domain. The targeting peptide generates a specific association with mosquitoes by causing the fused toxin peptide to bind mosquitoes in a way that leads to the insecticidal activity. Transgenic plants described herein are mosquitocidal by expressing an insecticidal toxin protein in nectar that includes a targeting peptide to ensure specificity against mosquitoes. These transgenic plants serve as role models for safety, since they are non-crop plants and specific to one mosquito species.

ABSTRACT

This invention relates to compositions and methods for modifying Homologous to E6AP C-Terminus (HECT) E3 Ubiquitin Protein Ligase (UPL) genes in plants, optionally to improve yield traits. The invention further relates to plants having increased improved yield traits produced using the methods and compositions of the invention.

The present invention relates to a method for increasing the expression and/or promoting correct folding of a heterologous polypeptide of interest in a plant cell, comprising co-expressing the heterologous polypeptide of interest with a polypeptide encoding a mammalian chaperone protein. The invention also relates to plant cells and plants, which either transiently or stably, co-express the heterologous polypeptide of interest and the chaperone protein.

Provided are compositions comprising polynucleotides encoding modified MFT polypeptides. Also provided are recombinant DNA constructs, plants, plant cells, seed, and grain comprising the polynucleotides. Additionally, methods using the polynucleotides in plants to increase seed oil and/or protein content are also provided herein.

The present disclosure provides compositions and methods for generating plants that can grow in saline conditions, or remove a salt or other impurity from water, for example plants that can remove sodium chloride from salt or sea water, and plants that can produce purified water from salt or sea water.

Provided herein are modified tomato plants comprising an introduced modification of genomic DNA at the SlFSR gene or a transcription regulatory region thereof. In some instances, the introduced modification is heritable. In some instances, the introduced modification is an epigenetic such as hypermethylation. Also provided are progeny plants produced from the modified tomato plants, tomato seeds and tomato fruit produced by the modified tomato plants or progeny plants. Also provided are methods of making and growing the modified tomato plant and obtaining modified tomato fruit as well as nucleic acid reagents useful in the methods.

The present invention relates to a method for producing a recombinant viral vector from hairy roots of a plant, in particular from hairy roots of a plant belonging to the Brassicaceae family. The invention also relates to a transgenic plant, a hairy root culture and a recombinant viral vector obtainable by the method of the invention.

Compositions and methods are provided for an inducible, high efficiency intra-genomic homologous recombination (IGHR) system in plants, that can be used for non-chimeric, heritable gene targeting. The advantage of IGHR approach to targeted integration is that every cell contains donor DNA and nuclease-encoding sequences, so that there are many potentially homology-directed targeting events that can occur during plant development.
