The invention provides Scaevola plants that produce at least one flower with a floral phenotype characterised by at least one of: a fused, or partially fused, dorsal slit, a radially, or near radially symmetrical, arrangement of petals, and delayed senescence. The phenotype is a result of reduced or eliminated expression or activity of a CYCLOIDEA2 (CYC2) gene or protein, and or presence of a novel allele designated the FUSED allele. The invention further provides plant cells, plant parts, propagules, seeds and tissue cultures of such plants. The invention further provides methods for the productions and selection of such plants, plant cells, plant parts, propagules, seeds and tissue cultures.

The present disclosure provides the identification of genes involved in sucker growth in tobacco. Also provided are promoters that are preferentially active in tobacco axillary buds. Also provided are modified tobacco plants comprising reduced or no sucker growth. Also provided are methods and compositions for producing modified tobacco plants comprising reduced or no sucker growth.

Novel sugarcane-derived flowering-inducing genes each encoding a protein comprising the amino acid sequence of SEQ ID NO: 2 or 4 (the ScFT6 gene and the ScZCN16 gene), by which the flowering time is accelerated more slowly than conventionally known flowering-inducing genes, are provided.

This invention relates to compositions and methods for modifying NAC7 genes in plants, optionally to improve yield traits. The invention further relates to plants having improved plant architecture and/or improved yield traits produced using the methods and compositions of the invention.

The present invention relates to the identification of monocot FLC sequences, such as wheat FLC sequences, as well as their uses in modulating flowering time, seed development and seed germination.

The present disclosure provides modified, transgenic, or genome edited/mutated corn plants that are semi-dwarf and have one or more improved ear traits and yield relative to a control plant, such as increased ear area, increased ear volume, increased single kernel weight, increased ear fresh weight, increased ear diameter, increased ear length, increased yield, increased kernels per ear, decreased ear tip void, and decreased ear void. The modified, transgenic, or genome edited/mutated corn plants comprise a transgene encoding one or more CONSTANS (CO) or CONSTANS-like (COL) polypeptides and a transgene encoding one or more MADS-box polypeptides, and can also have a reduced expression of one or more GA20 or GA3 oxidase genes. Also provided are methods for producing the modified, transgenic, or genome edited/mutated corn plants.

Isolated polynucleotides and polypeptides, and recombinant DNA constructs are useful for conferring delayed or accelerated flowering time and maturity. Compositions (such as plants or seeds) comprise these recombinant DNA constructs; and methods utilize these recombinant DNA constructs. The recombinant DNA constructs comprise a polynucleotide operably linked to a promoter that is functional in a plant, wherein said polynucleotides encode late flowering polypeptides.

The present invention relates to new double stranded RNA (dsRNA) structures and their use in modulating flowering in plants. The present invention also relates to methods of modulating the time of plant flowering.

Isolated polynucleotides and polypeptides, and recombinant DNA constructs are useful for conferring delayed or accelerated flowering time and/or maturity.

The recombinant DNA constructs comprise a polynucleotide operably linked to a promoter that is functional in a plant, wherein said polynucleotides encode late flowering polypeptides.

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.
