| 英文摘要 | Isoetes hypsophila Hand.-Mazz. (lsoetaceae) is an endangered quillwort endemic to the Qinghai-Tibetan Plateau. Genetic variation and population structure of 12 I. hypsophila populations were examined by using amplified fragment length polymorphism (AFLP) markers. Eight primer pairs produced a total of 472 unambiguous bands, of which 229 (48.5%) were polymorphic. Intra-population genetic variation of Isoetes hypsophila was low (P(p) = 14.9%, H(E) = 0.039, hs = 0.084 and I = 0.061). The F statistics calculated by different approaches consistently revealed high genetic differentiation among populations, contributing approximately 50% of total gene diversity. Four genetic groups corresponding to four geographic regions were detected, indicating significant geographic structure. Our results suggest that both ongoing evolutionary forces (e.g., inbreeding system, bottlenecks resulting from fluctuation of water level) and historical events (e.g., orogenic movements which reduce gene flow among populations, repeated population retreat, and recolonization during ice ages), may have contributed to the genetic structure of I. hypsophila. In conservation, attention should be paid to preserving every population, and intra-region translocations can currently be recommended. |
