Despite the tremendous success of Arabidopsis thaliana, no single model can represent the vast range of form that is seen in the approximately 250,000 existing species of flowering plants (angiosperms). Here, we consider the history and future of an alternative angiosperm model--the snapdragon Antirrhinum majus. We ask what made Antirrhinum attractive to the earliest students of variation and inheritance, and how its use led to landmark advances in plant genetics and to our present understanding of plant development. Finally, we show how the wide diversity of Antirrhinum species, combined with classical and molecular genetics--the two traditional strengths of Antirrhinum--provide an opportunity for developmental, evolutionary and ecological approaches. These factors make A. majus an ideal comparative angiosperm.
尽管拟南芥取得了巨大成功，但没有一个单一的模型能够代表现存约25万种开花植物（被子植物）所展现出的丰富多样的形态。在此，我们探讨另一种被子植物模型——金鱼草（Antirrhinum majus）的历史与未来。我们思考是什么让金鱼草吸引了最早研究变异与遗传的学者，以及它的应用如何推动了植物遗传学的里程碑式进展，进而促成了我们目前对植物发育的理解。最后，我们展示了金鱼草物种的广泛多样性，结合经典遗传学和分子遗传学——金鱼草的两大传统优势——如何为发育生物学、进化生物学和生态学研究方法提供了契机。这些因素使金鱼草成为理想的被子植物比较研究对象。
