    • The present invention relates generally to constructs and in particular genetic constructs comprising polynucleotide sequences capable of release in covalently closed, circular form from a larger nucleotide sequence such as, but not limited to, a genome of a eukaryotic cell. Preferably, once released, a polynucleotide sequence is reconstituted in a form which permits expression of the polynucleotide sequence. In one embodiment, the reconstituted polynucleotide sequence comprises a coding sequence with all or part of an extraneous nucleotide such as, but not limited to, intronic sequence or other splice signal inserted therein. Expression and in particular transcription of the coding sequence involves splicing out the extraneous sequence. The release and circularization is generally in response to a stimulus such as a protein-mediated stimulus. More particularly, the protein is a viral or prokaryotic or eukaryotic derived protein or developmentally and/or tissue specific regulated protein. The construct of the present invention is particularly useful in conferring genetic resistance against pathogens or inducing apoptosis or other cell death mechanisms useful, for example, in treating cancer or inducing male or female sterility in plants. The constructs permit, therefore, site specific expression and/or developmentally regulated expression of selected genetic sequences.
    • 本发明一般涉及构建体,特别是包含能够以较大核苷酸序列例如但不限于真核细胞基因组以共价闭合的环形形式释放的多核苷酸序列的构建体,特别是遗传构建体。 优选地,一旦释放,以允许多核苷酸序列表达的形式重构多核苷酸序列。 在一个实施方案中,重构的多核苷酸序列包含具有全部或部分外来核苷酸的编码序列,例如但不限于插入其中的内含子序列或其他剪接信号。 表达,特别是编码序列的转录涉及剪接外来序列。 释放和环化通常响应于诸如蛋白质介导的刺激的刺激。 更具体地,蛋白质是病毒或原核或真核衍生的蛋白质或发育和/或组织特异性调节蛋白。 本发明的构建体特别可用于赋予病原体的遗传抗性或诱导凋亡或其它细胞死亡机制,例如用于治疗癌症或诱导植物中的雄性或雌性不育。 因此,构建体允许选择的遗传序列的位点特异性表达和/或发育调节表达。
