A heat-tolerant tomato plant exhibiting a high capacity for developing seed-containing fruits under high temperature conditions is provided. The present invention relates to a method for producing a heat-tolerant tomato plant comprising introducing a genetic mutation into a tomato plant, wherein the mutation improves the pollen viability and the capacity for developing seed-containing fruits under high temperature conditions compared with wild-type plant; and a heat-tolerant tomato plant into which the mutation has been introduced.

Nucleotide sequences encoding RTL polypeptides are provided herein, along with plants and cells having increased levels of RTL gene expression, increased levels of RTL transcription factor activity, or both. Plants with increased levels of at least one RTL gene expression that exhibit reduced ethylene sensitivity, increased yield, increased abiotic stress tolerance, or any combination of these, are provided. Methods for increasing yield, and abiotic stress tolerance in plants, by modulating RTL gene expression or activity, are also provided.

The invention provides materials and methods for producing coreless fruit, or plants that produce coreless fruit. The invention involves combining reduced expression of AGAMOUS (AG) with parthenocarpy. Parthenocarpy can be induced by hormone treatment, or can be provided by reduced or eliminated expression of PISTILATA (PI) or APETALA3 (AP3). The invention provides methods and materials for producing the plants and coreless fruit by genetic modification (GM) and non-GM means. The invention also provides the plants and coreless fruit.

The present invention relates to a plant of the species Solanum lycopersicum comprising in its genome at least one copy of a mutant allele of the wild type ACO4 gene, wherein said mutant allele when present in homozygous form causes the fruits having an increased fruit firmness after the fruits entered the full red stage. The present invention further relates to a seed from which a plant according to present invention can be grown, a plant grown from the seed according to the present invention, a fruit produced by a plant according to the present invention and a part of a plant according to the present invention. The present invention further relates to a method for producing tomato fruit having an increased shelf life comprising growing a plant according to the present invention. The present invention further relates to a method of identifying and/or selecting a plant or plant part according to the present invention. The present invention further relates to a method of producing a plant of the species Solanum lycopersicum comprising in its genome at least one copy of a mutant allele of the ACO4 gene according to the present invention. The present invention further relates to the use of a plant of the species Solanum lycopersicum of the present invention for consumption or as a source of propagation material.

A genetically modified fruit-producing plant, said plant having sufficiently reduced total Polyphenol Oxidase (PPO) activity relative to a wild type of said plant to reduce browning in the fruit of said plant relative to said wild type, wherein the reduced total PPO activity results from a reduction in activity of at least two PPO isoenzymes in said plant relative to said wild type, or a cell, seed, seedling, part, tissue, cell, fruit or progeny of said plant.

Disclosed is a method for the production of a plant of the Cucurbitaceae family by mutating seeds to induce a mutation of 1-aminocyclopropane-1-carboxylate synthase 8 (ACS8) and growing a plant from the mutated seed, with the plant having a androecy or androecious tendency.

The present invention relates to ethylene insensitive EIN/EIL polypeptides, and nucleotide sequences encoding the EIN/EIL polypeptides. Further, the invention relates to plants having reduced ethylene insensitivity and methods for preparing these. Lastly, the invention relates to products and crops from plants as well as processed products derived from the products and crops.

A genetically modified fruit-producing plant, said plant having sufficiently reduced total Polyphenol Oxidase (PPO) activity relative to a wild type of said plant to reduce browning in the fruit of said plant relative to said wild type, wherein the reduced total PPO activity results from a reduction in activity of at least two PPO isoenzymes in said plant relative to said wild type, or a cell, seed, seedling, part, tissue, cell, fruit or progeny of said plant.

Provided herein are tomato plants and plant parts comprising altered expression, activity, or function of an SlAN2like transcription factor and/or an SlMYB-ATV transcription factor, and increased anthocyanin content. The tomato plants or plant parts provided herein can comprise one or more mutations in the Aft gene and the ATV gene. Also disclosed herein are compositions and methods of producing tomato plants and plant parts comprising increased anthocyanin content.

The present invention relates to a transcription factor gene that plays a key role in Solanaceae fruit ripening. Plants overexpressing the gene have fruits with deeper pigmentation and ripen more rapidly than controls. The invention also relates to transgenic plants comprising said gene, and methods of making said plants.
