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.

The present invention provides novel DNA molecules and constructs, including their nucleotide sequences, useful for modulating gene expression in plants and plant cells. The invention also provides DNA molecules and constructs, including their nucleotide sequences, useful for expressing proteins in plants to promote symbiotic infection. The invention also provides plants and plant cells transgenic plants, plant cells, plant parts, seeds, and commodity products comprising the DNA molecules operably linked to heterologous transcribable polynucleotides, along with methods of their use.

The present disclosure provides modified, transgenic, or genome edited/mutated corn plants that are semi-dwarf and have one or more improved ear traits relative to a control plant, such as increase in ear area, increased single kernel weight, increased ear fresh weight, increased number of florets, and mitigated flowering delay. The modified, transgenic, or genome edited/mutated corn plants comprise a transgene encoding one or more CONSTANS (CO) or CONSTANS-like (COL) polypeptide and 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.

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 present invention relates to excision of explant material comprising meristematic tissue from seeds, and storage of such material prior to subsequent use in plant tissue culture and genetic transformation. Methods for tissue preparation, storage, and transformation are disclosed, as is transformable meristem tissue produced by such methods, and apparati for tissue preparation.

The present invention relates to excision of explant material comprising meristematic tissue from cotton seeds. Methods for tissue preparation, storage, transformation, and selection or identification of transformed plants are disclosed, as are transformable meristem tissues and plants produced by such methods, and apparati for tissue preparation.

A transgenic rice plant containing in its genome a recombinant DNA construct that includes a first nucleic acid having a sequence of a first Golden 2-like transcription factor (GLK) gene operably linked to its natural promoter and 5′ untranslated region (5′UTR), and a second nucleic acid having a sequence of a second GLK gene operably linked to its natural promoter and 5′UTR, the second GLK gene being distinct from the first GLK gene. The first GLK gene and the second GLK gene are both from a C4 plant and the transgenic rice plant exhibits a 65-106% increase in shoot biomass and a 50-95% increase in grain yield, as compared to an untransformed wild-type rice plant. Also provided is a method for producing the transgenic rice plant and a recombinant DNA construct that can be used in the method.

The compositions and methods are provided that enhance the selection of transgenic plants having two T-DNA molecules integrated into a plant genome at different physical and genetic loci. The compositions are DNA constructs that comprise novel arrangements of T-DNA molecules containing genes of interest, positive selectable marker genes, and conditional lethal genes. The methods disclosed herein comprises transforming a plant cell to comprise the DNA constructs of the present invention, regenerating the plant cell into a plant and identifying independant transgene loci, where the selectable marker genes or transgenic elements can be segregated in the progeny.

The present invention relates to excision of explant material comprising meristematic tissue from cotton seeds. Methods for tissue preparation, storage, transformation, and selection or identification of transformed plants are disclosed, as are transformable meristem tissues and plants produced by such methods, and apparati for tissue preparation.

The technology provided herein generally relates relates to genetically modified higher plants, for example C3 and C4 plants, and subsequent generations thereof, comprising stable and/or transient expression of at least one gene-product (e.g. mRNA or protein) of the “Chlamydomonas reinhardtii CO2 concentrating mechanism” (CCM), wherein the expression takes place in the intermembrane space and/or one or more subcellular compartments of the chloroplasts of the higher plant, and wherein this expression increases one or more of the characteristics selected from the group of photosynthetic rate, photosynthetic carbon fixation, chlorophyll level and/or biomass of the genetically modified higher plant (T0) and/or of the T1 and/or T2 generation or any subsequent plant generation of said genetically modified higher plant.
