“…corticola. Elliptochloris subsphaerica possesses a pyrenoid and a more complex, multi-lobed chloroplast (Reisigl 1964). In E. reniformis, adult cells are mostly non-globular and chloroplast is typical by deeply lobed chloroplast, usually with three to more lobes (Watanabe 1977;Ettl & Gärtner 1995;Hanagata et al 1998).…”

We investigated a previously unidentified subaerial corticolous strain of the genus Elliptochloris TschermakWoess. The alga shares the generic morphological characters with Elliptochloris bilobata, the type species of the genus, but it has a thicker cell wall of adult globular cells, different chloroplast structure and it also differs in shape of elliptical autospores. The differences of the autospore shape between both species were evaluated using landmark-based geometric morphometrics. The 18S rDNA gene sequence of the new alga forms a monophyletic clade with the authentic strain of E. bilobata within the green algal class Trebouxiophyceae close to representatives of the genus Coccomyxa. We describe the new alga as Elliptochloris bilobata var. corticola var. nov.

“…The taxonomic position of this organism has been the subject of debate since it was first characterized. In the Culture Collection Algae of Charles University of Prague (CAUP), strain H4301 is named Myrmecia incisa Reisigl based on the description by Reisigl [1]. However, in Romania the same organism is named Lobococcus incisus (Reisigl) Reisigl, which is a synonym of M. incisa [2].…”

cDNA library of Myrmecia incisa H4301 was constructed using λ phage vectors. The library consisted of 1.5×10 6 clones with a recombination rate of 90%, and 1942 clones were randomly sequenced. All 1854 readable expressed sequence tags (ESTs) were clustered into 596 non-redundant sequences (NRSs), among which 126 NRSs were from 1384 ESTs, showing a high redundancy. Among the 596 NRSs, 30 were ribosomal RNA, and 152 significantly matched with those available in NCBI database and JGI Genome Portal, the latter were divided into nine subcategories. Overall, 59 NRSs were involved in photosynthesis, the respiratory electron transport chain, ATP synthesis, oxidation reduction, fatty acid biosynthesis, glucose metabolism, protein metabolism, and small molecular metabolism, suggesting that these genes were abundantly transcribed during energy and substance metabolism. Acyl-carrier protein, ferrodoxin and fatty acid elongase genes obtained from this cDNA library enabled presumption of a possible biosynthesis pathway of ArA in M. incisa. Codon usage analysis of 142 NRSs with 17798 codons in the predicted coding regions showed that the average G+C content level of the total codons was 55.39%, and that of the third position in base trimers was 66.42%, indicating a strong bias toward cytosine and/or guanosine in this algal genome. Among all synonymous codons, NAG was most favored, while NUA was most avoided. Phylogenic trees inferred from ribulose-1,5-bisphosphate carboxylase/oxygenase small subunit genes and the extra partial sequences of 18S rRNA obtained from this library demonstrated that M. incisa belonged to Trebouxiophyceae and was significantly clustered with M. incisa SAG 2007, Lobosphaera tirolensis, M. bisecta, and Parietochloris incisa, but was clearly distant from P. pseudoalveolaris and P. alveolar. Transmission electron microscopy revealed pyrenoids traversed by many parallel thylakoids membranes, while starch grains were only clearly observed when cells were grown under nitrogen stress. Based on combined investigation of the phylogeny and morphological characteristics, it is proposed that M. incisa be kept in the genus Myrmecia in which there might be two parallel groups, one living freely and another symbiotic species.
