Morphology, taxonomy, biogeography and ecology of Micrasterias foliacea Bailey ex Ralfs (Desmidiales, Zygnematophyceae) [PDF]
PhytoKeys, 2023 Micrasterias foliacea (Desmidiales, Zygnematophyceae) is an interesting desmid species as its filamentous life form is quite different from all other species within the genus.

DNA content variation and its significance in the evolution of the genus Micrasterias (Desmidiales, Streptophyta). [PDF]
PLoS ONE, 2014 It is now clear that whole genome duplications have occurred in all eukaryotic evolutionary lineages, and that the vast majority of flowering plants have experienced polyploidisation in their evolutionary history.

On processing field and culture samples of desmids (Desmidiales, chlorophyta) for scanning electron microscopy [PDF]
British Phycological Journal, 1976 A procedure is outlined for preparing both field collected and laboratory grown desmid populations for scanning electron microscopy which avoids the use of the potentially hazardous chemicals glutaraldehyde and osmium tetroxide and reduces preparation time substantially.

Symmetry, 2023 While ontogeny of multicellular organisms requires an interplay among tissues, morphogenesis of unicellular structures is typically organised with respect to differential growth of their cell covering. For example, shapes of various microalgae have often been emphasised as examples of symmetric fractal-like cellular morphology.

Molecular evolution of glutamine synthetase II: Phylogenetic evidence of a non-endosymbiotic gene transfer event early in plant evolution [PDF]
BMC Evolutionary Biology, 2010 Background Glutamine synthetase (GS) is essential for ammonium assimilation and the biosynthesis of glutamine. The three GS gene families (GSI, GSII, and GSIII) are represented in both prokaryotic and eukaryotic organisms.
