双孢蘑菇（Agaricus bisporus）是世界上栽培最广泛的食用菌，已知的栽培历史只有大约300年。因此，它代表了一种理想的生物，不仅可以研究自然进化史，而且可以追溯到驯化早期的进化。在本研究中，我们获得了352 A的线粒体基因组序列。bisporus菌株和来自世界各地4个近缘种的9个菌株。群体有丝分裂基因组学研究表明，所有的A。双孢菌株可分为7个分支，所有驯化的栽培品种仅存在于其中的两个分支中。分子年代学分析表明该种起源于4.6Ma的欧洲，并提出了主要的传播途径。详细的有丝分裂基因组结构研究表明，质粒衍生的dpo基因的插入引起了长片段倒位，dpo基因片段的分布与这7个分支严格对应。我们的研究也表明A. bisporus群体含有30个内含子分布模式（IDP），而所有栽培品种仅含有两个IDP，与其他品种相比明显表现出内含子丢失。无论是发生在驯化之前或之后的损失，这可能表明，这种变化有助于他们适应栽培环境。在线版本包含补充材料，可通过10.1186/s12864-023-09257-w获得。
Agaricus bisporus is the most widely cultivated edible mushroom in the world with a only around three hundred years known history of cultivation. Therefore, it represents an ideal organism not only to investigate the natural evolutionary history but also the understanding on the evolution going back to the early era of domestication. In this study, we generated the mitochondrial genome sequences of 352 A. bisporus strains and 9 strains from 4 closely related species around the world. The population mitogenomic study revealed all A. bisporus strains can be divided into seven clades, and all domesticated cultivars present only in two of those clades. The molecular dating analysis showed this species origin in Europe on 4.6 Ma and we proposed the main dispersal routes. The detailed mitogenome structure studies showed that the insertion of the plasmid-derived dpo gene caused a long fragment (MIR) inversion, and the distributions of the fragments of dpo gene were strictly in correspondence with these seven clades. Our studies also showed A. bisporus population contains 30 intron distribution patterns (IDPs), while all cultivars contain only two IDPs, which clearly exhibit intron loss compared to the others. Either the loss occurred before or after domestication, that could suggest that the change facilitates their adaptation to the cultivated environment.
