测定了甘蔗叶绿体基因组的全序列。它是一个环状双链DNA分子，大小为141，182 bp，由一个83，048 bp的大单拷贝、一个12，544 bp的小单拷贝和一对各为22，795 bp的反向重复区组成。在单子叶植物中的比较分析表明，甘蔗叶绿体基因组与玉米非常相似，但与水稻或小麦不同。甘蔗和玉米之间的rps 16-trnQ（UUG）区域，然而，长度多态性被确定。对于等于或大于5 bp的插入/缺失，在甘蔗叶绿体基因组中总共鉴定出53个插入事件和31个缺失事件。在所鉴定的84个位点中，有47个位点（56.0%）的一对直接重复序列以串联方式并排定位。植物进化过程中的重组事件进行了讨论，在两个网站之间的甘蔗和烟草叶绿体基因组。
The complete nucleotide sequence of the chloroplast genome of sugarcane (Saccharum officinarum) has been determined. It is a circular double-stranded DNA molecule, 141,182 bp in size, and is composed of a large single copy of 83,048 bp, a small single copy of 12,544 bp, and a pair of inverted repeat regions of 22,795 bp each. A comparative analysis among monocots showed that the sugarcane chloroplast genome was very similar to maize but not to rice or wheat. Between sugarcane and maize at the rps16-trnQ (UUG) region, however, a length polymorphism was identified. With regard to insertions/deletions equal to or longer than 5 bp, a total of 53 insertion and 31 deletion events were identified in the sugarcane chloroplast genome. Of the 84 loci identified, a pair of direct repeat sequences was located side by side in a tandem fashion in 47 loci (56.0%). A recombination event during plant evolution is discussed at two sites between the sugarcane and tobacco chloroplast genomes.
