Abstract
C. Liu, X. Huang, X. Wang, X. Zhang and G. Li. 2006. Phylogenetic studies on two strains of Antarctic ice algae based on morphological and molecular characteristics. Phycologia 45: 190–198. DOI: 10.2216/03-88.1The taxonomic characterization of two strains of Antarctic ice algae, Chlamydomonas sp. ICE-L and Chlamydomonas sp. ICE-W, were analyzed on the basis of morphological and molecular traits. The results indicate that they are the same species and belong to Chlamydomonas (Chlorophyta). According to 18S rDNA and ITS-1 sequences they are very close relatives of Chlamydomonas sp. Antarctic 2E9, if not ide.gified as such. They belong to the ‘monadina clade’, Cd. monadina and Cm. subdivisa as the sister group, on the basis of 18S rDNA sequence. They occur in ‘Chlamydomonas clade’ according to rbcL sequencing and are close relatives of Cd. kuwadae. The ITS sequences of ICE-L and ICE-W are 1302 base pairs and 1300 base pairs in length, the longest Volvocales ITS sequences ever reported.
