The taxonomic placement of strains belonging to the extremophilic red alga Galdieria maxima has been controversial due to the inconsistent phylogenetic position inferred from molecular phylogenetic analyses. Galdieria maxima nom. inval. was classified in this genus based on morphology and molecular data in the early work, but some subsequent molecular phylogenetic analyses have inferred strains of G. maxima to be closely related to the genus Cyanidioschyzon. To address this controversy, an…

Resolving Complexities in Taxonomic Lineages of the Organellar and Nuclear Genomes of Galdieria through Comparative Phylogenomic Analysis

Phylogenetic analysis based on a few plastid and nuclear genes highlighted the intricate genetic structure of Galdieria and the hypothesis of diverging clades within the G. sulphuraria species and resolved enigmatic relationships between lineages.

The Unicellular Red Alga Cyanidioschyzon merolae—The Simplest Model of a Photosynthetic Eukaryote

The features and experimental techniques of C. merolae are summarized and it is clear that this unicellular red alga—either alone or in comparative and combinatory studies with other photosynthetic organisms—can provide significant insights into the biology of photosynthesis eukaryotes.

Independent Size Expansions and Intron Proliferation in Red Algal Plastid and Mitochondrial Genomes

New mitochondrial and plastid genomes from 25 red algal species are described, thereby substantially expanding the amount of organellar sequence data available, especially for Proteorhodophytina, and it is shown that genome expansions are common in this group.

Life cycle and functional genomics of the unicellular red alga Galdieria for elucidating algal and plant evolution and industrial use

The finding of sexual reproduction in the unicellular red alga Galdieria provides information on the missing link of life cycle evolution in Archaeplastida, and the newly found cell wall–less haploid makes cell disruption less energy/cost intensive than the cell-walled diploid.

Cyanidiales as Polyextreme Eukaryotes

The ability to survive in stressful habitats and the corresponding metabolic pathways were acquired by Cyanidiales from archaea and bacteria via horizontal gene transfer (HGT), which was a new step in understanding of the origin of eukaryotic cell.

The carbon-concentrating mechanism of the extremophilic red microalga Cyanidioschyzon merolae.

Cyanidioschyzon merolae is an extremophilic red microalga which grows in low-pH, high-temperature environments. The basis of C. merolae's environmental resilience is not fully characterized,…

Dynamics of pelagic mucilage produced by the invasive, cyclotelloid diatom, Lindavia intermedia, in oligotrophic lakes of New Zealand

Marine pelagic mucilages (e.g., marine snow) have been reported to a greater extent than their lacustrine counterparts. A pelagic mucilage primarily comprised of chitin secretions from the invasive…

Fifth addendum to the synoptic review of red algal genera

31 new genera, three new families, two new orders, and one new subphylum from the past three years, as well as listing four genera reinstated from synonymy based upon molecular sequencing studies.

Biochemical and spectroscopic characterization of PSI-LHCI from the red alga Cyanidium caldarium.

Light-harvesting complexes (LHCs) have been diversified in oxygenic photosynthetic organisms, and play an essential role in capturing light energy which is transferred to two types of photosystem…

Genome-wide signatures of adaptation to extreme environments in red algae

Analysis of chromosome-level assemblies from three representative Cyanidiophyceae species finds that horizontal gene transfer, subtelomeric gene duplication, and loss of genes or reduction in gene family size have supported key extremophilic adaptations.

Hidden biodiversity of the extremophilic Cyanidiales red algae

The research revealed an unexpected level of genetic diversity among Cyanidiales that revises current thinking about the phylogeny and biodiversity of this group and predicts that future environmental PCR studies will significantly augment known biodiversity that is discovered and demonstrate the Cyanidials to be a species‐rich branch of red algal evolution.

Biogeography of the Cyanidiaceae (Rhodophyta) based on 18S ribosomal RNA sequence data

Comparison of 18S sequences from thermo-acidophilic red algae indicates that even within a seemingly homogeneous group of eukaryotic organisms the limits of phylogenetic analysis may be reached.

Comparative Genomics of Two Closely Related Unicellular Thermo-Acidophilic Red Algae, Galdieria sulphuraria and Cyanidioschyzon merolae, Reveals the Molecular Basis of the Metabolic Flexibility of Galdieria sulphuraria and Significant Differences in Carbohydrate Metabolism of Both Algae1

It is proposed that genes involved in the uptake of reduced carbon compounds and enzymes involved in their metabolism are crucial to the metabolic flexibility of G. sulphuraria.

Biogeographic and Phylogenetic Diversity of Thermoacidophilic Cyanidiales in Yellowstone National Park, Japan, and New Zealand

The phylogenetic diversity of culture isolates of the Cyanidiales from habitats throughout Yellowstone National Park, three areas in Japan, and seven regions in New Zealand was examined by using the chloroplast RuBisCO large subunit gene (rbcL) and the 18S rRNA gene.

Molecular variation in Galdieria sulphuraria (Galdieri) Merola and its bearing on taxonomy

The results support the status of the genus Galdieria and suggest that G. sulphuraria accessions from Naples (Italy), California, and Yellowstone and from the Russian species are in a sister group relationship with this last genus.

Analysis of rbcL sequences reveals the global biodiversity, community structure, and biogeographical pattern of thermoacidophilic red algae (Cyanidiales)

This study is the first examination of the global species diversity and biogeographic affinity of cyanidia and the influence of microhabitat type on Cyanidiales diversity and highlights intriguing questions for future ecological research.

Genome sequence of the ultrasmall unicellular red alga Cyanidioschyzon merolae 10D

The results indicate that the C. merolae genome provides a model system with a simple gene composition for studying the origin, evolution and fundamental mechanisms of eukaryotic cells.

Molecular support for the establishment of the new genus Laurenciella within the Laurencia complex (Ceramiales, Rhodophyta)

The phylogenetic position of this group, combined with the high genetic divergence from Laurencia s.s. (8.2–11%), strongly support the establishment of a sixth genus for the complex, proposed here as Laurenciella gen. nov.

The phylogenetic results suggest that the Cyanidiophyceae, including C. merolae, are a basal clade within the red lineage plastids, and several genes that are rarely found in other plastid genomes are identified.

Cyanidiophyceae in Iceland: plastid rbcL gene elucidates origin and dispersal of extremophilic Galdieria sulphuraria and G. maxima (Galdieriaceae, Rhodophyta)

On the basis of network analysis of rbcL haplotypes, it is likely that the southwestern region of Iceland is the diversity center of both G. sulphuraria and G. maxima from northeastern Asia.
