The extent of the conservation of synteny and gene order in aphids has been previously investigated only by comparing a small subset of linkage groups between the pea aphid and a few other aphid species. Here we compared the localization of eight scaffolds (covering more than 5 Mb and 83 genes) in respect to the Muller elements identifying orthologous loci spanning all the four chromosomes. Comparison of the genetic maps revealed a conserved synteny across different loci suggesting that the study of the fruit fly Muller elements could favour the identification of chromosomal markers useful for the study of chromosomal rearrangements in aphids. is the first aphid species to have its genome sequenced and the finding that there are several chromosomal regions in synteny between Diptera and Hemiptera indicates that the genomic tools developed in will be broadly useful not only for the study of other aphids but also for other insect species.
以前，人们仅通过比较豌豆蚜和其他几种蚜虫的一小部分连锁群，来研究蚜虫中基因顺序和基因同线性的保存程度。在这里，我们比较了 8 个支架（覆盖超过 5Mb 和 83 个基因）的定位，以确定跨越所有 4 条染色体的 Muller 元件的同源基因座。遗传图谱的比较揭示了不同基因座之间的保守同线性，这表明研究果蝇 Muller 元件有助于确定对研究蚜虫染色体重排有用的染色体标记。是第一个测序基因组的蚜虫物种，并且在双翅目和半翅目之间有几个染色体区域具有同线性，这表明在中开发的基因组工具不仅对其他蚜虫的研究，而且对其他昆虫物种的研究都将具有广泛的用途。
