Abstract
Hybridization and polyploidization are important evolutionary processes in higher plants and have greatly enriched the diversity of the genus Potamogeton (Potamogetonaceae). To study the phylogenetic relationships and hybrid origin of Potamogeton species, 35 accessions representing 20 species, including diploids, tetraploids and hexaploids, and three hybrids were collected in China and their ribosomal internal transcribed spacers (ITS) were cloned, sequenced and statistically analyzed. The data showed that ITS sequences were informative to analyze the phylogeny of Potamogeton, and the phylogenetic tree revealed that Potamogeton species examined could be mainly divided into two groups (Group I and II), corresponding to subgenus Potamogeton and subgenus Coleogeton, respectively. Then, the evolutionary mechanism on the polyploidy of Potamogeton species was discussed. P. natans probably was an allotetraploid and one of its parent might result from aneuploidy change of species with 2n=28. P. hubeiensis might be derived from the hybridization between P. octandrus and P. cristatus. We suggested that both P. lucens and P. maackianus probably were allotetraploids, and P. obtusifolius might be a diploid hybrid between P. compressus and P. pusillus. Moreover, P. malainoides might have undergone biased concerted evolution toward one of its parent P. wrightii, and P. intortusifolius might be a synonymy of P. × anguillanus.
