Reexamination of the genus Pterocladiella (Gelidiaceae, Rhodophyta) in Korea based on morphology and rbcL sequences

摘要: Although Pterocladiella is a well-known agar-producing red algal genus, its taxonomy in Korea appears to be confused. In the present study, we demonstrate occurrence of nana and P. tenuis, as well capillacea on basis morphological plastid rbcL sequence comparisons. commonly occurs along coasts has regular pinnate branches with abundant second-order branches, growing up 10 cm length. intertidal zone Jeju distinguished by small size thalli (up 5 cm) third-order branches. tenuis distributed mostly subtidally southern coast irregular rarely 19 We determined sequences from specimens (15 four France) downloaded 28 GenBank. Analyses all 47 revealed that each three species was consistently resolved. always formed sister clade at base. Given 12 haplotypes have been found date, analysis fast-evolving gene across range should highlight genetic diversity.
