The complete nucleotide sequence of a rice nuclear 17S rRNA gene (rDNA) has been determined. The rice rDNA is 1812 bp long and its G + C content is 51.3%. This nucleotide sequence shows 79%, 80% and 80% homology to those of yeast, Xenopus laevis and rat 18S rDNAs, respectively. Divergency of nucleotide sequences is largely attributed to five blocks of highly variable regions, where eukaryotic specific sequences can be observed.
已确定水稻核17S rRNA基因(rDNA)的完整核苷酸序列。水稻rDNA长1812 bp,其G + C含量为51.3%。该核苷酸序列与酵母、非洲爪蟾和大鼠的18S rDNA序列的同源性分别为79%、80%和80%。核苷酸序列的差异主要归因于五个高度可变区,在这些区域可观察到真核生物特有的序列。
