The present invention concerns a nucleic acid molecule capable of expressing, in at least one plant tissue, a chimeric protein comprising a polygalacturonase (PG) of fungal, bacterial or insect origin and a plant polygalacturonase inhibitor protein (PGIP) plant capable of inhibiting said PG. The present invention also relates to transgenic plants that express said chimeric protein.

The invention provides seed and plants of tomato hybrid SV2794TD and the parent lines thereof. The invention thus relates to the plants, seeds and tissue cultures of tomato hybrid SV2794TD and the parent lines thereof, and to methods for producing a tomato plant produced by crossing such plants with themselves or with another tomato plant, such as a plant of another genotype. The invention further relates to seeds and plants produced by such crossing. The invention further relates to parts of such plants, including the fruit and gametes of such plants.

Provided herein are compounds and methods for increasing disease resistance and/or root length in plants.

Compositions and methods are provided for regulated expression of a guide RNA/Cas endonuclease system in a plant cell, plant and seed. Compositions and methods are also provided for genome modification of a target sequence in the genome of a plant or plant cell. The methods and compositions employ a regulated guide RNA/Cas endonuclease system to provide an effective system for modifying or altering target sites within the genome of a plant, plant cell or seed.

Provided are constructs and methods for expressing a transgene in plant cells and/or plant tissues using gene regulatory elements obtained from Brassica napus.

Disclosed herein are methods of controlling insect pests, in particular Leptinotarsa spp. which infest crop plants, and methods of providing plants resistant to such pests. Also disclosed are polynucleotides and recombinant DNA molecules and constructs useful in such methods, insecticidal compositions such as topical sprays containing insecticidal double-stranded RNAs, and solanaceous plants with improved resistance to infestation by Leptinotarsa spp. Further disclosed are methods of selecting target genes for RNAi-mediated silencing and control of Leptinotarsa spp.

Compositions and methods for down-regulating genes through oral administration of RNAi molecule encapsulated in plant cells are provided.

The invention provides seed and plants of tomato hybrid DR0603TC and the parent lines thereof. The invention thus relates to the plants, seeds and tissue cultures of tomato hybrid DR0603TC and the parent lines thereof, and to methods for producing a tomato plant produced by crossing such plants with themselves or with another tomato plant, such as a plant of another genotype. The invention further relates to seeds and plants produced by such crossing. The invention further relates to parts of such plants, including the fruit and gametes of such plants.

The invention pertains to a method for synthesizing a product of interest by culturing a microalgal cell producing the product of interest in the dark in a culture medium comprising an organic acid as a fixed carbon source, wherein the microalgal cell is a facultative heterotroph. The product of interest can be a microalgal biomass, a pigment, terpene, recombinant molecule, biogas, or a precursor thereof. In an embodiment, the culture medium comprises urea as a primary source of nitrogen. In one embodiment, the microalgal cell belongs to the order Chlamydomonadales. A method of identifying and isolating a microalgal cell having a preferred characteristic that is suitable for synthesis of a product of interest is also provided, the method comprising identifying and isolating a non-mutagenized or recombinant microalgal cell from a microalgal culture using a fluorescence activated cell sorting technique and/or a phototaxic response.
