Phylogenetic Relationships Among Eleven Yellow-Flowered Camellia Species Based on Random Amplified Polymorphic DNA
11种金花茶植物的RAPD分析及其系统学意义

Eleven species of yellow-flowered Camellia were analyzed using random amplified polymorphic DNA (RAPD) markers. Fourteen decanucleotide primers of arbitrary sequences were selected from 140 primers for DNA amplification. 201 bands were used as markers. Based on the RAPD data, a phenogram has been constructed. The result shows that: (1) C. micrantha and C. fusuiensis are closely related to C. achrysantha ; (2) C. chrysan- thoides and C. grandis form a monophyletic group with C. xiashiensis; (3) There is a close relationship among C. longzhouensis, C. ptilosperma, C. longruiensis, which form another monophyletic group; (4) C. impressinervis is highly divergent from all the othertaxa.
