Taxonomy Detail

Order Mamiellales

Mamiellales Moestrup, 1984: 112.

Original publication: Moestrup, Ø. (1984). Further studies on Nephroselmis and its allies (Prasinophyceae). II. Mamiella gen. nov., Mamiellaceae fam. nov., Mamiellales ord. nov.. Nordic Journal of Botany 4: 109-121.

Description:
Unicellular algae, living in marine habitats. Cell dimensions about 0.5-7 µm, cells with 1 or 2 flagella, or without flagella. Covered with spider web scales, composed of concentric and radiating ribs, or without scaly covering. Chloroplasts with prasinoxanthin, micromonal, and Unidentified M1. Unique molecular synapomorphies: spacer between Helices E23_13 and E23_14 (reverse strands) in the nuclear 18S rRNA comprising 8 (usually UUGGUCUC) instead of 9 nucleotides; single stranded nucleotide nt 890 in Helix H885 of the plastid-encoded 16S rRNA is U instead of G; base pair 1005/1138 within Helix H1005 of plastid-encoded 23S rRNA is U-A instead of C-G; amino acid 340 of RuBisCO (large subunit) is Asn instead of Glu.

Taxonomic notes:
