Microbial eukaryotes encompass the majority of eukaryotic evolutionary and cytoskeletal diversity.
Our understanding of the eukaryotic tree of life and the tremendous diversity of microbial eukaryotes is in flux as additional genes and diverse taxa are sampled for molecular analyses.
The continued development of molecular genetic tools in these complex microbial eukaryotes will undoubtedly contribute to our overall understanding of cytoskeletal diversity and evolution.
In more recent years, a remarkable discovery has been that of giant viruses with very large genomes (over 300 Kbp and up to 1.2 Mbp) infecting amoeba and other microbial eukaryotes (protists).
The cytoskeletal complexity observed in multicellular organisms appears to be an expansion of components present in genomes of diverse microbial eukaryotes such as the basal lineage of flagellates, the Excavata.
Shikimate dehydrogenase (EC 1.1.1.25) catalyses the fourth step of the shikimate pathway which is required for the synthesis of the aromatic amino acids and other aromatic compounds in bacteria, microbial eukaryotes, and plants.
Among microbial eukaryotes, dinoflagellates contain the largest number of genes in their nuclear genomes.
The communities of microbial eukaryotes in temperate habitats appear less diverse and not as rich.
One would expect this to manifest today as a diversity of deeply rooted microbial eukaryotes with anaerobic life style.
We argue that the greatest utility of the method is in uncovering novel diversity in microbial eukaryotes.
Here we examine a link between the diversity of microbial eukaryotes and paleoclimate events over the course of their evolution.
