摘要: It has been considered that genus Cosmarium including Staurastrum had the problems in grouping by morphological characters. Sequence data for Cytochrome Oxidase subunit III (coxIII) were employed to compare with taxa of two divisions this genus, sections each, evaluating taxonomic stability these The division and section systems not coincided phylogeny inferred from coxIII sequences, as previous reports us using nuclear rDNA ITS chloroplast rbcL sequence comparisons genus. Two placed within a same clade each other, one taxon was grouped Arthrodesmus clade. genera, Staurastrum, cannot be regarded monophyletic result. Mitochondrial gene useful phylogenetic tool evaluate evolutionary relationships desmids case land plants.耀Ѐ€€က
