Members of the euasterid angiosperm family Solanaceae have been characterized as remarkably diverse in terms of flower morphology and pollinator type. In order to test the relative contribution of phylogeny to the pattern of distribution of floral characters related to pollination, flower form and pollinators have been mapped onto a molecular phylogeny of the family. Bilateral flower symmetry (zygomorphy) is prevalent in the basal grades of the family, and more derived clades have flowers that are largely radially symmetric, with some parallel evolution of floral bilateralism. Pollinator types ('syndromes') are extremely homoplastic in the family, but members of subfamily Solanoideae are exceptional in being largely bee pollinated. Pollinator relationships in those genera where they have been investigated more fully are not as specific as flower morphology and the classical pollinator syndrome models might suggest, and more detailed studies in some particularly variable genera, such as Iochroma and Nicotiana, are key to understanding the role of pollinators in floral evolution and adaptive radiation in the family. More studies of pollinators in the field are a priority.
茄科植物具有显著多样化的花形态和传粉者类型。为了测试系统发育对与传粉相关的花部特征分布模式的相对贡献，我们将花形态和传粉者映射到该科的分子系统发育树上。双边花对称性（左右对称）在科的基部等级中很常见，而更衍生的类群的花主要是辐射对称的，花的双边性也有一些平行进化。在茄科中，传粉者类型（“综合征”）极其同形，但是在茄亚科中，成员主要是蜜蜂传粉。在那些被更充分研究的属中，传粉者关系并不像花形态和经典传粉综合征模型所暗示的那样具体，而在一些特别可变的属（如 Iochroma 和 Nicotiana）中进行更详细的研究是理解传粉者在花部进化和适应性辐射中的作用的关键。在该科中，更多地研究野外传粉者是当务之急。
