“…Phylogenies based on 18S have identified multiple clades within the Trebouxiophyceae, including the Chlorellales, Geminella , Oocystis , Prasiola , Microthamniales , Trebouxiales, Watanabea , Choricystis , and Ellipotochloris clades, as well as several other lineages consisting of a single species or genus (e.g., Pleurastrosarcina , Xylochloris , and Lobosphaera ). The relationship among these clades, however, was largely unresolved based on 18S data (Karsten et al, ; Eliáš et al, ; Darienko et al, ; Neustupa et al, , ; Bock et al, ).…”

Green plants comprise two main clades: the Streptophyta, which include charophyte green algae and the embryophytic land plants, and the Chlorophyta including a wide diversity of marine, freshwater, and terrestrial green algae. Establishing a robust phylogeny is important to provide an evolutionary framework for comparative and functional studies. During the last two decades our understanding of the evolution of green algae has profoundly changed, first by phylogenetic analyses of nuclear ribosomal sequence data (mainly 18S), and more recently by analyses of multi‐gene and chloroplast genomic data. The phylogenetic relationships among the main streptophytan lineages have been extensively studied and are now relatively well resolved. Although a lot of progress has been made in the last few years, the phylogenetic relationships in the Chlorophyta are still less well established. Here we review how chloroplast genomic data have contributed to address relationships among the main chlorophytan lineages. We highlight recent progress and conflicts among different studies, and discuss future directions in chloroplast phylogenomics of green algae.

“…Pseudococcomyxa has only rarely been reported as the photobiont of lichen fungi (Muggia et al 2010), but this fact certainly reflects problems using morphology to distinguish Pseudococcomyxa from Coccomyxa, and recent work by Pröschold et al demonstrated that the authentic strain of P. simplex SAG 216-9a belongs within the genus Coccomyxa in the Elliptochloris clade (2011). On the other hand, some species from the genus Elliptochloris (for example, Elliptochloris bilobata Tsch.-Woess) are widely recognized as symbionts in lichens (Tschermak-Woess 1985) and as free-living algae of sub-aerial habitats (Eliáš et al 2008;Tsarenko 2011). Other species in the genus are recognized as photobionts in marine invertebrates (Letsch et al 2009) or as freeliving terrestrial algae (Ettl & Gärtner 1995).…”

Lichenization is a symbiotic ecological strategy that is widely distributed among the fungi, but in which the diversity of partners is relatively poorly known. Limited morphological diversity has hindered the recognition of true diversity in many lichen fungi, and also in their algal partners. In the temperate and boreal zones, the crustose microlichens are the most speciose but arguably the least studied, particularly in terms of their photobiont partners. In this study, we sampled eight species of Micarea s. str. collected from Europe, culturing and sequencing their green-algal partners using chloroplast (rbcL) and nuclear ribosomal (nucSSU) markers. All specimens collected in Great Britain were associated with members of Coccomyxa (including Pseudococcomyxa), but in the smaller sample of Ukrainian material, both Coccomyxa and Elliptochloris were found. This study extends the known range of fungal hosts for symbionts in the genus Coccomyxa, and supports earlier findings that a separate lineage of predominantly non-symbiotic Coccomyxa exists.

“…Recently, subaerial microalgae from southeast Asian tropical rainforest habitats gained increased interest by a series of studies [10][11][12][13][14] which lead to the establishment of two new genera of green algae, Jenufa [13] and Xylochloris [14]. Both genera appeared as somehow distant to any known genera of green algae, despite a taxon sampling as large as possible that has been applied in the 18S rDNA sequence analyses of both studies.…”

Molecular Evidence for the Wide Distribution of Two Lineages of Terrestrial Green Algae (Chlorophyta) over Tropics to Temperate Zone

Phylogenetic analyses of 18S rDNA sequences from environmental clones and culture strains revealed a widespread distribution of two subaerial green algal lineages, Jenufa and Xylochloris, recently described from rainforests in southeast Asia. A new lineage of Jenufa (Chlorophyceae), most closely related to or even conspecific with J. minuta, was formed by sequences of European origin. Two more lineages of Jenufa were formed by three additional sequences from Ecuador and Panama. The other lineage was a close relative of Xylochloris irregularis (Trebouxiophyceae), probably representing a new species of the genus and distinct from the only so far described species, X. irregularis. It comprised two distinct clades each containing almost identical sequences from Germany and Ecuador. Analyses of the new sequences for both genera allowed to presume a preference of J. minuta to subaerial growth on rock or artificial hard substrates combined with a remarkable adaptation to extended periods of darkness, whereas Xylochloris may preferably occur on tree bark or in the soil.
