| 英文摘要 | Revealing cryptic diversity is of great importance for effective conservation and understanding macroevolution and ecology of plants. Ottelia, a typical example of aquatic plants, possesses extremely variable morphology and the presence of cryptic diversity makes its classification problematic. Previous studies have revealed cryptic Ottelia species in Asia, but very little is known about the molecular systematics of this genus in Africa, a center of species diversity of Ottelia. In this study, we sampled Ottelia ulvifolia, an endemic species of tropical Africa, from Zambia and Cameroon. We used six chloroplast DNA regions, nrITS and six polymorphic microsatellite markers to estimate the molecular diversity and population genetic structure in O. ulvifolia. The phylogenetic inference, STACEY and STRUCTURE analyses supported at least three clusters within O. ulvifolia, each representing unique flower types (i.e., bisexual yellow flower, unisexual yellow flower and bisexual white flower types). Although abundant genetic variation (> 50%) was observed within the populations, excessive anthropogenic activities may result in genetic drift and bottlenecks. Here, three cryptic species of O. ulvifolia complex are defined, and insights are provided into the taxonomy of Ottelia using the phylogenetic species concept. |
