我们分析了矮牵牛(Mitchell)二磷酸核酮糖羧化酶小亚基和叶绿素a/b结合蛋白基因和玉米(Zea mays)青铜基因的聚腺苷化位点。多个cDNA克隆的序列分析显示,三组基因的转录本在2或3个位点发生多聚腺苷化。在检测到3个聚腺苷化位点的例子中,中间位点是主要使用的位点。假定的聚A尾部前的聚腺苷化信号与动物一致的序列AATAAA明显不同。在所有被检测的基因中,cDNA克隆的多A尾部的第一个A残基与同源基因组序列中的一个A残基相对应。
We have analyzed the polyadenylation sites for the small subunit of ribulose bisphosphate carboxylase and chlorophyll a/b binding protein genes of Petunia (Mitchell) and the bronze gene of Zea mays. Sequence analysis of multiple cDNA clones revealed that polyadenylation of the transcripts occurred at either 2 or 3 sites for all three groups of genes. In the examples where 3 polyadenylation sites were detected, the middle site was the one predominantly used. Putative polyadenylation signals preceding the poly A tails diverged significantly from the animal consensus sequence AATAAA. In all the genes examined the first A residue in the poly A tail of the cDNA clones corresponded to an A residue in the homologous genomic sequence.
