“…In conclusion, although previous studies concerning molecular identification of some algae from other Middle East countries (Attaran-Fariman and Javid, 2013;AttaranFariman and Bolch, 2014) are available, to the best of our knowledge, this preliminary study is the first phylogenetic investigation to determine the algal diversity of Anatolian freshwaters and contains the first reports for Chlorella sorokiniana and Heterochlorella luteoviridis species. In addition to these 2 new records, it also contains the first phylogenetically identified true Chlorella vulgaris isolates.…”

IntroductionMany coccoid algae are very difficult to identify because of their extremely small size and simple morphology, and they have been referred to as "little green balls" (Callieri and Stockner, 2002). These little green balls have often been reported as Chlorella Beijerinck or Chlorella vulgaris Beijerinck (Fawley et al., 2004). Since C. vulgaris "Beijerinck strain" (SAG 211-11b) was first described and isolated in axenic culture about 120 years ago, Chlorella strains have been used as model organisms in plant physiology and biochemical research (Burja et al., 2001). Furthermore, mass cultures of Chlorella have been used in agriculture as a single cell protein both for humans and animals, in biotechnology as recovery agents for waste treatment, and in biofuel technology as microbial energy producers (Golueke and Oswald, 1964;Fogg, 1971;Soeder, 1976;Abbott and Cheney, 1982).Among the over 100 traditionally defined Chlorella species, a lack of morphological characters led to the adoption of various approaches, including several combinations of physiological, biochemical, and serological studies, for identifying Chlorella species (John et al., 2003). The morphologically-defined species are considered very artificial and house many cryptic taxa. Using molecular data, Huss et al. (1999) demonstrated that only 5 "true" species could be regarded as part of the genus Chlorella. Materials and methods Chlorella isolationsEnvironmental water samples were taken from the

In the north part of the Oman and Arabian seas phytoplankton blooms occur during and after the north-east monsoon every year (Attaran-Fariman and Javid, 2013;Latif et al, 2013).

Morphology and genetic affinities of a novel Chattonella isolate (Raphidophyceae) isolated from Iran’s south coast (Oman Sea)

The morphology and genetic affinity of a novel raphidophyte belonging to the genus Chattonella Biecheler is described for the first time from the Oman Sea along the south-east coast of Iran. While morphologically very similar to Chattonella subsalsa Biecheler, the Iranian isolates contain a distinct red eyespot. A comparison of LSU-rDNA and rDNA-ITS show that the Iranian isolate is genetically distinct from other Chattonella subsalsa strains isolated from across a wide global range and indicates that the Iranian isolates represent a distinct species related to Chattonella subsalsa.

Harmful algal blooms (HABs) threaten the aquatic ecosystems due to either poisonous effects on living organisms or oxygen-consuming. So HABs’ accurate identification, including red tide, is crucial. This study aimed to molecular identification of dominant species during tide period in nine stations along Alexandria region at Egyptian costs during one year. Samples were collected weekly before water discoloration but daily during red tide intensive growth from both 50 cm below the surface and 3 m depth over the bottom from the water surface. The red tide detection was highly from early August to half of September, since its highest peak with a maximum frequency inside the Eastern Harbor. The examined cultures samples isolated during red tide had four dominant species. Peroxidase profile showed an expression pattern of three loci (Px1, Px2, and Px3) in most species. The Px2 was the only heterozygous locus among the three loci in all species. Protein profiling showed that 17 bands out of 65 were specific to the species. The phylogenetic relationships derived from profiles of protein and 18S rRNA gene operon sequences for the four isolated species were mostly similar. We identified the four dominant HABs species as Aplanochytrium sp., Chlamydomonas sp., Cryptophyceae sp., and Psammodictyon sp. based on their 18S rRNA sequences and deposited them at DDBJ/EMBL/GenBank database. Aplanochytrium sp. is recorded as a red tide causative species for the first time in the screened region despite belonging to the defunct fungi.
