The disclosure provides a plant of variety NUN 53050 CUP as well as seeds and plants and fruits thereof. NUN 53050 CUP is a parthenocarpic pickling cucumber variety comprising resistance to Cladosporium cucumerinum (Cucumber Scab) and Erysiphe chicoracearum (Powdery Mildew).

Methods and materials for modulating cold tolerance levels in plants are disclosed. For example, nucleic acids encoding cold tolerance-modulating polypeptides are disclosed as well as methods for using such nucleic acids to transform plant cells. Also disclosed are plants having increased cold tolerance levels and plant products produced from plants having increased cold tolerance levels.

A method for introducing a genome editing enzyme into a plant cell includes: treating the cell with plasma; and then bringing the cell into contact with the genome editing enzyme in the presence of a di- or higher-valent metal cation.

The invention provides seeds and plants of tomato hybrid DRTC6031. The invention thus relates to the plants, seeds, plant parts, and tissue cultures of tomato hybrid DRTC6031 and to methods for producing a tomato plant produced by crossing such plants with themselves or with another plant, such as a tomato plant of another genotype. The invention further relates to seeds and plants produced by such crossing. The invention further relates to plants, seeds, plant parts, and tissue cultures of tomato hybrid DRTC6031 comprising introduced beneficial or desirable traits.

The disclosure relates to melon variety NUN 71248 MEM as well as seeds and plants and fruits thereof. NUN 71248 MEM is a Honeydew melon variety comprising resistance to Podosphaera xanthii Race 1 (IR), Race 2 (IR), and Race 5 (IR), Muskmelon Necrotic Spot Virus (MNSV), and Aphis gossypii (Ag).

Conventional gene transformation requires tissue culture, and some elite lines have very low transformation efficiency in tissue culture. The disclosure relates to methods of in planta transformation. In some aspects, an axillary meristem of a plant is wounded and contacted with a transformation agent. The wounded axillary meristem is then regenerated and treated with a selection step, resulting in transformed tissue that can produce transgenic seeds.

A method to transforming a plant includes coating a microparticle having a diameter of 0.3 to 0.9 μm with at least one type of nucleic acid, bombarding a shoot apex of the plant with the coated microparticle using a gene gun, growing the shoot apex bombarded with the coated microparticle to obtain a plant body, and selecting a transformed plant body from the plant body. The shoot apex is selected from the group consisting of a shoot apex of an embryo of a fully mature seed, a shoot apex of a young bud of a tuber, and a shoot apex of a terminal bud or a lateral bud.

The present invention relates to a method for conducting high-throughput and directed mutagenesis for sugarcane resistance to glyphosate by plasma. The method is as follows: sugarcane embryonic calli are irradiated by a plasma instrument under a sterile condition for mutagenesis, wherein the mutagenesis power is 140˜200 W, the discharging distance is 35˜45 mm, the mutagenesis time is 110˜140 s and the protective gas is nitrogen; buffering culture, moderate/high concentration of glyphosate stress screening, differentiation into seedlings, glyphosate stress screening of bottle seedlings and stress screening via spraying glyphosate on the leave surfaces of potted plants are conducted for the treated calli. The present invention has the advantages of safe operation, simplicity, practicability, high handling capacity, low contamination, and due to implementation of directed stress screening, high screening efficiency, decreased subsequent screening workload and visual identification of resistant mutant strains.

The invention provides seeds and plants of tomato line FIR-XM15-4367. The invention thus relates to the plants, seeds, plant parts, and tissue cultures of tomato line FIR-XM15-4367 and to methods for producing a tomato plant produced by crossing such plants with themselves or with another plant, such as a tomato plant of another genotype. The invention further relates to seeds and plants produced by such crossing. The invention further relates to plants, seeds, plant parts, and tissue cultures of tomato line FIR-XM15-4367 comprising introduced beneficial or desirable traits.

The present invention is directed to methods and compositions for breeding plants with an altered flavor or odor profile. Particularly, next generation plant breeding technologies are utilized for producing plants with target genes edited to reduce pungency in flavor or odor. The breeding method is capable of producing mustard plants in which the mustard bomb reaction is disarmed and/or plants with a reduced pungency and/or bitterness in flavor and/or odor.
