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 the use of Argonaute systems in plants for genome engineering, and compositions used in such methods.

Pairs of plants are provided in which complementing constructs result in suppression of a parental phenotype in the progeny. Methods to generate and maintain such plants and methods of use of said plants, are provided, including use of parental plants to produce sterile plants for hybrid seed production. Also provided are methods for maintaining a homozygous recessive condition and for repressing transmission of transgenes.

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.

This disclosure concerns compositions and methods for promoting transcription of a nucleotide sequence in a plant or plant cell, employing a promoter from a Glycine max egg cell gene. Some embodiments relate to a promoter or a 5′ UTR from a Glycine max egg cell gene that functions in plants to promote transcription of operably linked nucleotide sequences. Other embodiments relate to a 3′ UTR or a terminator from a Glycine max egg cell gene that functions in plants to promote transcription of operably linked nucleotide sequences.

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.

The present invention is directed to seedless fruit producing plants. The present invention also comprises methods for production of said plants and the use of nucleic acids encoding cyclin SDS like proteins for the production of seedless fruits.
