Abstract

The gene encoding subunit III of cytochrome oxidase (COXIII) has been identified in the sunflower mitochondrial genome. The COXIII coding region is located 570 bp downstream of a 477 bp open reading frame (ORFB). Sequence comparisons and hybridization experiments show that ORFB sequences are conserved in other plant mitochondrial genomes. Nucleotide and amino acid sequence comparisons suggest that RNA editing is required in sunflower mitochondria to synthesize a functional COXIII polypeptide.

摘要

细胞色素氧化酶（COXIII）亚基III的编码基因已在向日葵线粒体基因组中被鉴定出来。COXIII编码区位于一个477bp的开放阅读框（ORFB）下游570bp处。序列比较和杂交实验表明，ORFB序列在其他植物线粒体基因组中是保守的。核苷酸和氨基酸序列比较表明，向日葵线粒体中需要进行RNA编辑以合成功能性的COXIII多肽。
