Esterase-based resistance in the peach-potato aphid, Myzus persicae (Sulzer), is generally due to one of two alternative amplified carboxylesterase genes, E4 or FE4 (fast E4). The E4 amplified form is distributed worldwide and it is correlated with a particular translocation between autosomes 1 and 3, whereas the FE4 form, which has hitherto not been found to be associated with chromosomal rearrangements, is typical of the Mediterranean regions. In this study, we present for the first time cytogenetic and molecular data on some M. persicae parthenogenetic lineages, which clearly show a chromosomal A1-3 translocation associated with esterase FE4 genes and unrelated to high levels of esterase-based resistance.
桃蚜（Myzus persicae (Sulzer)）中基于酯酶的抗性通常归因于两个选择性扩增的羧酸酯酶基因E4或FE4（快速E4）之一。E4扩增形式分布于全球，它与常染色体1和3之间的特定易位相关，而FE4形式迄今未发现与染色体重排有关，是地中海地区的典型特征。在本研究中，我们首次展示了一些桃蚜孤雌生殖谱系的细胞遗传学和分子数据，这些数据清楚地表明存在与酯酶FE4基因相关且与高水平酯酶抗性无关的染色体A1 - 3易位。
