摘要： The plant gene TFIID encodes DNA-binding protein necessary for the transcription of all structural genes. Down-regulation of the expression of TFIID, by transformation with a sense or antisense copy of the TFIID gene, prevents expression of the gene, leads to a failure of transcription and, consequently, cell death. Such down-regulation may be targeted to particular cell types or to particular development stages by the selection of suitable promoters. Since TFIID is expressed in all cells at all times, its promoter is truly constitutive in effect and may be used to drive constitutive expression of foreign genes placed downstream thereof.
摘要翻译：植物基因TFIID编码所有结构基因转录所必需的DNA结合蛋白。通过TFIID基因的正义或反义拷贝的转化，TFIID表达的下调阻止基因的表达，导致转录失败，从而导致细胞死亡。这种下调可以通过选择合适的启动子来靶向特定的细胞类型或特定的发育阶段。由于TFIID始终在所有细胞中表达，因此其启动子是真正有组成的，可用于驱动其下游放置的外源基因的组成型表达。

摘要： A method for enhancing the expression of a selected gene in an organism while avoiding or reducing co-suppression involves the synthesis of a DNA which is altered in nucleotide sequence and is capable of expression of a protein, ideally identical to that of a protein already expressed by a DNA already present in the organism. This method ensures that sequence similarity between the two genes is reduced enough to eliminate the phenomenon of co-suppression, allowing the over-expression of a specific protein. The method is particularly suitable in plants.
摘要翻译：增强生物体中所选基因表达的方法，同时避免或减少共抑制，涉及DNA的合成，其在核苷酸序列中被改变并且能够表达蛋白质，理想地与已表达的蛋白质相同已经存在于生物体中的DNA。该方法确保两个基因之间的序列相似性足够减少以消除共抑制现象，允许特异性蛋白质的过表达。该方法特别适用于植物。

摘要： The invention relates to a chemically-inducible plant gene expression cassette and to plant cells transformed therewith. The expression cassette is suitable for use in any dicothyledonous or monocotyledonous plant. It comprises a first promoter operatively linked to a regulator sequence which encodes a regulator protein, and an inducible promoter operatively linked to a target gene, the inducible promoter being activated by the regulator protein in the presence of an effective exogenous inducer whereby application of the inducer causes expression of the target gene. The regulator sequence may be derived from the alcR gene, and the inducible promoter may be derived from the alcA gene promoter (both obtainable from Aspergillus nidulans) A chimeric promoter comprising an upstream regulatory region and a heterologous downstream transcription initiation region is also disclosed. The regulatory sequence may be derived from the alcA gene promoter.
