Provided herein is a method for improving growth, stress tolerance and productivity of a plant. Also provided herein is a method for increasing seed quality of a plant. Specifically, the disclosure provides a method for improving growth, stress tolerance and productivity of a plant, comprising: providing a transgenic plant, which includes a reduced expression on an MYBS2 gene as relative to its wild-type counterpart; and a method for increasing seed quality of a plant, comprising: providing a seed from a transgenic plant, which overexpresses a full-length MYBS2 gene or a mutant MYBS2 gene as relative to its wild-type counterpart.

Provided are isolated polynucleotides and recombinant DNA constructs encoding polypeptides useful for conferring accelerated or delayed flowering time and/or maturity. Compositions (such as plants or seeds) comprising these recombinant DNA constructs; and methods utilizing these recombinant DNA constructs are also provided.

The present invention relates to non-transgenic and transgenic plants, preferably crop plants, comprising at least one mutation of the KINTEOCHORE NULL2 (KNL2) protein, especially a mutation causing a substitution of an amino acid within the KNL2 protein, preferably within the C-terminal region of the KNL2 protein, which preferably have the biological activity of a haploid inducer. Further, the present invention provides methods of generating the plants of the present invention and haploid and double haploid plants obtainable by crossing the plants of the present invention with wildtype plants as well as methods of facilitating cytoplasm exchange.

The present invention provides a polynucleotide which enables the modulation of the seed vigour, and in particular enhances the seed vigour, and more particularly enables the modification of the speed of germination. A plant seed comprising the said polynucleotide is also provided. A method of producing the plant seed, method for improving the germination and vigour of plant seed, transgenic plant and the use of the polynucleotide of the invention for producing plants growing seeds with improved germination and vigour characteristics are also provided. The invention particularly concerns Brassica, more particularly Brassica oleracea.

The invention provides methods and compositions for identifying transgenic seed that contain a transgene of interest, but lack a marker gene. Use of an identification sequence that results in a detectable phenotype increases the efficiency of screening for seed and plants in which transgene sequences not linked to a gene of interest have segregated from the sequence encoding a gene of interest.

The invention relates to plant transcription factor polypeptides, polynucleotides that encode them, homologs from a variety of plant species, and methods of using the polynucleotides and polypeptides to produce transgenic plants having advantageous properties compared to a reference plant. Sequence information related to these polynucleotides and polypeptides can also be used in bioinformatic search methods and is also disclosed.

The present invention relates to mutant gibberellin 2-oxidase (GA2ox) genes and uses thereof. In particular, the effective mutations disclosed herein can reduce GA2ox enzymatic activity to different extents, leading to various degrees of GA deficient yet beneficial agronomic traits in transgenic plants.

A modified plant is provided. The modified plant includes a polynucleotide including a promoter operably linked to a coding sequence. The coding sequence encodes a transcription factor that has at least 30% sequence identity to one or more of SEQ ID NOs: 27, 204, 10, 19, 1-9, 11-18, 20-26, 28-203, 205, 237, or 242-310. The promoter is non-cognate with respect to the coding sequence. Also provided is a method for producing a modified plant having increased seed yield and/or oil content in comparison to a reference plant by transformation. Also provided is a method for producing a modified plant having increased seed yield and/or oil content in comparison to a reference plant by editing.

Transgenic seed for crops with enhanced agronomic traits are provided by trait-improving recombinant DNA in the nucleus of cells of the seed where plants grown from such transgenic seed exhibit one or more enhanced traits as compared to a control plant. Of particular interest are transgenic plants that have increased yield. The present invention also provides recombinant DNA molecules for expression of a protein, and recombinant DNA molecules for suppression of a protein.

Disclosed are rice environmental conditional-lethal mutant gene osesl1, an encoding protein and use thereof The gene osesl1 has a nucleotide sequence shown as SEQ ID NO: 1 in the Sequence Listing. The encoding protein thereof has an amino acid sequence shown as SEQ ID NO: 2. After heading of osesl1 mutant rice, seed embryo lethal phenotype appears at 12 days after pollination, exhibiting darkening at the junction between embryo and endosperm. When an average temperature is below 22° C., a seed embryo is normal; when the average temperature is above 28° C., the seed embryo is lethal; when the temperature is between 22° C. and 28° C., the seed embryo is lethal under long daylight conditions (>13 h) and normal under short daylight conditions (<13 h). Use of the gene osesl1 in controlling seed embryo development of rice is further provided.
