Heterospory (i.e. dimorphic spores) is a long-lasting topic discussed in plant biology. It is observed in many of ferns, fern allies, and seed plants. The rise of heterospory and the mechanisms underlying its success in plant evolution are not clearly elucidated. In this short communication, an attempt is made to shed some light on these two questions.
异孢现象(即二型孢子)是植物生物学中一个长期讨论的话题。在许多蕨类植物、蕨类植物近缘类群和种子植物中都有观察到。异孢现象的兴起及其在植物进化中成功的机制尚未得到明确阐明。在这篇简短的通讯中,试图对这两个问题进行一些阐释。
