茄子的驯化起源研究——综合谱系地理学、历史学和语言学证据

茄子是一种世界性的重要蔬菜作物， 但茄子驯化起源的地点和次数一直模糊不清。谱系地理学方法是解决此类问题的重要手段，同时，历史学和语言学证据也有重要的辅助作用。为此，我们将在茄子野生祖先种的分布区内广泛取样，并搜集各地茄子的栽培品种，利用谱系地理学方法研究单倍型在种群内、种群间的地理分布格局，重建茄子及其野生祖先种的谱系分化历史；同时搜集各地有关茄子的语言学和历史学证据，以期追溯茄子驯化起源的过程。这不仅可以帮助解决上述茄子的驯化起源问题，而且有助于深入理解茄子及其野生祖先种的遗传多样性，可以为茄子野生种质资源的有效收集、保存和利用提供依据。

Eggplant (Solanum melongena L.) is one of the most important vegetable crops in the world. However, the questions about its domestication origin location(s) and single or multiple domestication(s) are still unknown. Phylogeography is a suitable approach in resolving the two questions.Evidence from history and linguistics are also instructive. We will do population samples in the distribution areas of the wild ancestors of eggplant and collect different eggplant cultivars. Then phylogeographical methods will be conducted to reveal the geographical distributions of various haplotyes. The history of lineages differentiation of eggplant and its wild ancestors will be reconstructed. On the same time, we will collect and analyze data from history and linguistics to trace the domestication process of the eggplant. This work will not only resolve the questions about eggplant domestication origin, but also contribute key information on the genetic diversity of wild eggplant populations, and lay solid scientific foundations for the collection, conservation and utilization of the useful germplasm of the wild eggplant.
