Recently diverged species often show incomplete reproductive isolation and subsequently experience hybridization and introgression. The plant genus Mimulus includes many such examples of closely related taxa that prove useful for studying incipient speciation. However, Sandstedt et al. (4) show that in contrast to other Mimulus species, species of the M. tilingii complex are characterized by strong postzygotic isolation mediated by multiple barriers. This finding highlights the diverse speciation histories of related plant groups. This article is protected by copyright. All rights reserved.

文摘：合子后隔离在 Mimulus 物种形成中的作用

最近分化的物种通常表现出不完全的生殖隔离，随后会经历杂交和基因渗入。植物属 Mimulus 包括许多密切相关的分类群的例子，这些例子证明对研究早期物种形成很有用。然而，Sandstedt 等人。(4) 表明，与其他 Mimulus 物种相比，M. tilingii 复合体物种的特征是由多重屏障介导的强合子后隔离。这一发现突出了相关植物群的不同物种形成历史。本文受版权保护。版权所有。
