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 invention provides a compositions and methods for controlling phenotypic traits in plants. Genes of interest are placed under the control of a gene switch to allow inducible control or expression of a gene of interest “on-demand” by treatment of the plant with a chemical ligand.

The present invention provides recombinant DNA constructs, vectors and molecules useful for attenuating and/or refining the expression of a florigenic FT gene or transgene using targeting sequences of small RNA molecules. Transgenic plants, plant cells and tissues, and plant parts comprising the recombinant constructs, vectors, and molecules are also provided. Transgenic plants comprising a florigenic FT transgene may produce more bolls, siliques, fruits, nuts, or pods per node on the transgenic plant via suppression, relative to a control or wild type plant. Methods are further provided for introducing the recombinant DNA constructs, vectors, and molecules into a plant, and planting transgenic plants in the field including at higher densities. Transgenic plants of the present invention may provide greater yield potential than wild type or control plants.

A method of inducing genetic recombination, including: allowing a protein having DNA double-stranded cleavage activity to act in cells of a eukaryotic organism which is a polyploidy inherently possessed by a eukaryotic organism. In eukaryotic organisms, various genetic recombination generates new genome set composition. This is done to obtain a population of eukaryotic organisms that hold the modified genomic set.

Provided herein are genetically-altered Solanaceae plants, compositions related to the Solanaceae plants, and methods of making the Solanaceae plants.

The present invention includes a seed, a plant, a protoplast, a hybrid and methods of making the same of a cotton cultivar recombinantly modified overexpresses at least one of AtRAV1, AtRAV2 to confer longer fibers to transgenic cotton plants under drought conditions without an effect on yield.

There is described herein a mutant, non-naturally occurring or transgenic plant or part thereof having reduced expression of the gene encoding Terminal Flower 1 (TFL1) or reduced activity of the protein encoded by TFL1, said TFL1 comprising, consisting or consisting essentially of (i) a polynucleotide sequence comprising, consisting or consisting essentially of a sequence having at least 72% sequence identity to SEQ ID NO:7 or SEQ ID NO:8 or SEQ ID NO:10 or SEQ ID NO:11 or SEQ ID NO:19 or SEQ ID NO:20; or (ii) a polypeptide encoded by the polynucleotide set forth in (i); or (iii) a polypeptide having at least 72% sequence identity to SEQ ID NO:9 or SEQ ID NO:12 or SEQ ID NO:21; wherein the expression or activity of the polynucleotide or the polypeptide set forth in (i), (ii) or (iii) is reduced as compared to a control plant in which the expression or activity of the polynucleotide or the polypeptide set forth in (i), (ii) or (iii) has not been reduced.

Polynucleotides incorporated into nucleic acid constructs have been introduced into plants and were ectopically expressed. The encoded polypeptides of the invention have been shown to confer at least one regulatory activity and confer earlier flowering, longer floral organ retention, increased cold tolerance, greater tolerance to water deprivation, altered carbon-nitrogen balance sensing, increased low nitrogen tolerance, and/or increased tolerance to hyperosmotic stress as compared to a control plant.

Provided are isolated polynucleotides and nucleic acid constructs which comprise a nucleic acid sequence at least 80% identical to a nucleic acid sequence selected form the group consisting of SEQ ID NOs: 1-219, 367-5628, 9688-9700, and 9709-9752; and isolated polypeptides which comprise an amino acid sequence at least 80% homologous to an amino acid sequence selected from the group consisting of SEQ ID NOs: 220-366, 5629-9400, 9701-9708, and 9753-9796. Also provided are transgenic cells and plants expressing same and methods of using same for increasing yield, growth rate, biomass, vigor, oil content, seed yield, fiber yield, fiber quality, nitrogen use efficiency, and/or abiotic stress of a plant.

Cloning and use of an Arachis hypogaea L. flowering habit gene AhFH1 and allelic variants thereof are provided. Through experiments, the Arachis hypogaea L. flowering habit gene AhFH1 and two defunctionalized allelic variants thereof are determined. The defunctionalized allelic variants can cause the change from alternate flowering Arachis hypogaea L. to continuous flowering Arachis hypogaea L. Through overexpression of the gene AhFH1 or supplementary expression of a promoter of the gene itself, a continuous flowering Arachis hypogaea L. variety can be changed into alternate flowering Arachis hypogaea L.; and through knockout or expression suppression of the gene AhFH1, alternate flowering Arachis hypogaea L. can be changed into continuous flowering Arachis hypogaea L. Marker-assisted selection (MAS) breeding is realized for allelic variants of the gene using molecular markers.
