Abstract:

Internal transcribed spacer (ITS) sequences of nuclear ribosomal DNA from 30 taxa of section Camellia were sequenced and analyzed. Taking C. sinensis as an outgroup, phylogenetic analysis of ITS sequences was conducted by using PAUP4.0. The results indicated that the most plant in section Camellia formed a monophyletic group. This group could be divided into two main clades (clade I and clade II). The clade I included the species distributed in central south and southeast of China, supported by bootstrap value of 79 %. The species distributed in southwest China formed another clade with bootstrap value of 92 %. The taxonomic and evolutional relationships in section Camellia were discussed based on the phylogenetic analysis of ITS sequences, morphological characters and geographical distribution.

Key words: Camellia, Section Camellia, ITS sequence, phylogeny
