【摘要】 动物基因组基因在植物中不能转录或正确加工。植物不能识别动物基因的转录起始、转录终止和加工信号。用cDNA代替基因组编码序列,在植物中有作用启动子和终止子调节下,来自动物的cDNA都可以在植物中有效地转录和翻译。更多还原

【Abstract】 Animal genomic genes can not be transcripted and efficiently processed in transgenic plants. The promoters of animal genes are not utilized in transferd plant cells. The introns present in chimeric animal genes may also be unpredictably handed. And plant cells do not properly recognize animal gene polyadenyla-tion signals. These troubles are circuvented when animal cDNAs, instead of genomic sequence, were placed under the control of plant promoters, and flanked by plant polyadenylation signals at the 3’ end.更多还原
