The features and problems of taxonomical identification of green algae are discussed in this review. The examples of the polyphyly in some genera of Chlorophyta and the difficulties of selection of diagnostic morphological properties are given. The new approach to study of biodiversity – DNA-barcoding are considered, its steps and requirements to DNA-barcodes are described. The advantages and disadvantages of eventual DNA-barcodes for green algae are shown. The data on successful usage of certain primers are presented for a number of green algae.
Keywords: DNA-barcoding, green algae, molecular markers
