| 英文摘要 | Ceratopteris thalictroides (L.) Brongn. (Parkeriaceae) is a difficult fern species to taxonomically classify. Three cryptic species were revealed in the previous studies, referred to as the north type, the south type, and the third type. Because much of the distribution range of C. thalictroides in China was not included in the sampling of the previous studies, the taxonomic complexity of C. thalictroides in China remained uncertain. In order to identify the uncharacterized cryptic species, we examined four chloroplast DNA (cpDNA) non-coding regions and compared sequence variation within this species complex. Sequence data were obtained from 143 individuals in 24 populations throughout the natural distribution of the species in China. Nineteen haplotypes were identified. Molecular systematic and phylogeographical analyses revealed two genetically distinct clusters of cpDNA haplotypes in China. One cluster included haplotypes associated with the north type, and another with the south type cryptic species. The N (ST) value was significantly higher than the G (ST) value (N (ST) = 0.768 > G (ST) = 0.434, P < 0.05), indicating the presence of a significant phylogeographical structure of C. thalictroides in China. The results of AMOVA analysis showed a significant inter-group differentiation (F (ST) = 0.918; P < 0.001). Analyses based on different, but complementary methods suggest that in China, C. thalictroides contains only two of the cryptic species (the north and south types). Two haplotypes, H8 and H17, of the interior node in the minimum-spanning network (MSN) of cpDNA haplotypes are widespread. The origin of the widespread haplotypes in China may have resulted from long-distance dispersal to China. |
