对植物驯化历史的了解有助于了解植物适应和多样化的一般机制，并可以指导旨在改善栽培物种的育种计划。栽培树牡丹（属芍药L.）是世界上最流行的观赏植物之一；然而，它们的驯化历史仍未得到解决。在此，我们探讨了中国历史栽培牡丹（即普通和耀斑栽培的树牡丹）的驯化是一个单一的事件还是独立的驯化。本研究利用14个核微卫星标记和全国553种牡丹的综合资料，包括普通牡丹、斑牡丹和可能成为栽培牡丹的野生种或亚种，即芍药（Paeonia rockii ssp）。罗基，P.罗基。atava， P. jishanensis和P. decomposition。分配方法、主成分分析和近似贝叶斯计算为吉山牡丹和罗基牡丹这两种不同的异域野生品种的独立驯化提供了明确的证据。分别atava。这项研究提供了第一个来自不同物种和地点的栽培树木独立驯化的例子。这项工作也为最受欢迎的木本观赏植物之一的驯化历史提供了至关重要的见解。栽培的牡丹代表了平行和趋同进化的一个有趣的例子。本研究结果对改进牡丹的育种策略和了解牡丹的驯化、多样化和适应机制具有重要意义。
An understanding of plant domestication history provides insights into general mechanisms of plant adaptation and diversification and can guide breeding programmes that aim to improve cultivated species. Cultivated tree peonies (genus Paeonia L.) are among the most popular ornamental plants in the world; yet, the history of their domestication is still unresolved. Here, we explored whether the domestication in China of historically cultivated peonies, that is, the common and flare cultivated tree peonies, was a single event or whether independent domestications occurred. We used 14 nuclear microsatellite markers and a comprehensive set of 553 tree peonies collected across China, including common tree peonies, flare tree peonies and the wild species or subspecies that are potential contributors to the cultivated tree peonies, that is, Paeonia rockii ssp. rockii, P. rockii ssp. atava, P. jishanensis and P. decomposita. Assignment methods, a principal component analysis and approximate Bayesian computations provided clear evidence for independent domestications of these common tree and flare tree peonies from two distinct and allopatric wild species, P. jishanensis and P. rockii ssp. atava, respectively. This study provides the first example of independent domestications of cultivated trees from distinct species and locations. This work also yields crucial insight into the history of domestication of one of the most popular woody ornamental plants. The cultivated peonies represent an interesting case of parallel and convergent evolution. The information obtained in this study will be valuable both for improving current tree peony breeding strategies and for understanding the mechanisms of domestication, diversification and adaptation in plants.
