The rplI gene encoding the ribosomal protein L9 was found 4 kbp downstream from the desA gene, but on the opposite strand, in the genome of the cyanobacterium Synechocystis PCC6803. The deduced amino acid sequence is homologous to the sequences of the L9 proteins from Escherichia coli and chloroplasts of Arabidopsis and pea. The gene is present as a single copy in the chromosome and is transcribed as a mRNA of 0.64 kb. An open reading frame of unknown function (ORF291) was found in the upstream region of the rplI gene.
在集胞藻PCC6803的基因组中，编码核糖体蛋白L9的rplI基因位于desA基因下游4千碱基对处，但在相反的链上。推导的氨基酸序列与来自大肠杆菌、拟南芥叶绿体和豌豆的L9蛋白序列同源。该基因在染色体中以单拷贝形式存在，并转录为0.64千碱基的信使核糖核酸。在rplI基因的上游区域发现了一个功能未知的开放阅读框（ORF291）。
