    摘要: The present invention relates to the use of DNA sequence motifs to regulate gene expression in a tissue- or developmental-specific manner in transgenic plants. The invention generally relates to the engineering and use of G-box related sequence motifs, specifically Iwt and PA motifs, which function as cis-elements of promoters, to regulate the expression of heterologous genes in transgenic plants. PA enhances high level expression in roots, low level expression in leaves and little or no expression in seeds. By contrast, Iwt confers preferential expression in seeds, but in a developmentally-regulated manner.

    摘要: A transacting DNA binding factor is disclosed. The ASF-1 protein factor specifically binds to the sequence motif TGACG found upstream of the promoter in many plant genes. Co-expression of this protein factor augments the level of expression of the up-regulated promoter containing the TGACG motif.

    摘要: A group of genes including GhCIR1 from cotton (Gossypium hirsutum), and AtCIR1 and AtCIR2 from Arabidopsis thaliana promote shoot regeneration in plants even in the absence of cytokinin. In the presence of cytokinin, the genes significantly improve transformation efficiency. The genes can be used as an enhancer as well as a selectable marker of transformation in plants. The proteins encoded by the novel genes have a homeodomain (HD) at the N-terminus and a highly divergent domain at the C-terminus. The proteins share a common structural motif.

    摘要: The present invention relates to methods for promoting somatic embryogenesis from a plant cell, tissue, organ, callus or cell culture, by overexpressing a PGA37 gene in the tissue or organ. In one embodiment, such overexpression can be used as a silent selectable marker for transgenic plants. In another embodiment, such expression can be used to confer apomixis to a plant. In another embodiment, such overexpression can be used to create haploid plants, which can be used to produce dihaploid plants.

    摘要: A plant gene, Esr 1, has been found which when overexpressed in plant cells results in cells which have cytokinin-independent cell growth. This feature allows the encoded protein ESR1 to be used as a selectable marker of transformed cells by growing the transformed cells on cytokinin-free media. It has also been found that overexpression of ESR1 in cells grown in the presence of cytokinins results in a higher regeneration of plants. This feature allows the gene to be used to obtain greater regeneration of plant cells.

    摘要: A chemically inducible promoter is described that may be used to transform plants, including tobacco and lettuce, with genes which are easily regulatable by adding the plants or plant cells to a medium containing an inducer of the promoter or by removing the plants or plant cells from such medium. The promoter described is one that is inducible by a glucocorticoid which is not endogenous to plants. Such promoters may be used with a variety of genes such as ipt or knotted1 to induce shoot formation in the presence of a glucocorticoid. The promoter may also be used with antibiotic or herbicide resistance genes which are then regulatable by the presence or absence of inducer rather than being constitutive. Other examples of genes which may be placed under the control of the inducible promoter are also presented.

    摘要: Chemically inducible promoters are described that may be used to transform plants, including tobacco and lettuce, with genes which are easily regulatable by adding the plants or plant cells to a medium containing an inducer of the promoter or by removing the plants or plant cells from such medium. The promoters described are ones that are inducible by a glucocorticoid or estrogen which is not endogenous to plants. Such promoters may be used with a variety of genes such as ipt, CKI1, or knotted1, to induce shoot formation in the presence of an appropriate inducer. The promoters may be used with genes which induce somatic embryos such as Lec1 or SERK to prepare somatic embryos which can be grown into seedlings and then into plants. The promoter may also be used with antibiotic or herbicide resistance genes which are then regulatable by the presence or absence of inducer rather than being constitutive. Other examples of genes which may be placed under the control of the inducible promoter are also presented.
