“…Amorphea includes opisthokonts, Amoebozoa, and several protist lineages of uncertain phylogenetic placement, such as apusomonads, ancryomonads, and the breviate amoebae. (Heiss et al 2011;Katz et al 2011;Brown et al 2013). The rest of eukaryotes comprises excavates and the recently erected mega-clade Diaphoretickes (Adl et al 2012), which recognizes the SAR and Archaeplastida clade (Burki et al 2008) and corresponds to the corticates of Cavalier-Smith (2010a).…”

Molecular phylogenetics has revolutionized our knowledge of the eukaryotic tree of life. With the advent of genomics, a new discipline of phylogenetics has emerged: phylogenomics. This method uses large alignments of tens to hundreds of genes to reconstruct evolutionary histories. This approach has led to the resolution of ancient and contentious relationships, notably between the building blocks of the tree (the supergroups), and allowed to place in the tree enigmatic yet important protist lineages for understanding eukaryote evolution. Here, I discuss the pros and cons of phylogenomics and review the eukaryotic supergroups in light of earlier work that laid the foundation for the current view of the tree, including the position of the root. I conclude by presenting a picture of eukaryote evolution, summarizing the most recent progress in assembling the global tree.

“…DUF3361 is found only in proteins within the ELMO subfamily with two notable exceptions. One of the five ELMOD family members (ElmoD_A) in the apusomonad Thecamonas trahens, a putative sister group to the Opisthokonta supergroup (50,51), and one of six ELMOD family members (ElmoA) in the amoebozoan D. discoideum contains DUF3361 but no PH domain. These proteins did not cluster with the ELMO subfamily, but no strongly supported nodes separated them.…”

Background: ELMOD family proteins function either as Rac guanine nucleotide exchange factors or Arf GTPase-activating proteins. Results: The ELMOD family spans eukaryotic diversity and contains a putative catalytic arginine, essential for Arf GAP function. Conclusion:The ELMOD family is ancient, and GAP activity lies within the ELMO domain. Significance: This study establishes a function of the ELMO domain as a GTPase activating domain.

“…Breviates ( Breviata , Subulatomonas ) are microaerophilic gliding amoebofl agellates with a single anterior fl agellum (Walker et al 2006 ;Katz et al 2011 ). They are superfi cially similar to pelobionts (Amoebozoa), but different in the shape of pseudopodia, the presence of outer dynein arms and the structure of the fl agellar apparatus.…”

“…They engulf large preys such as other protists and cyanobacteria, and play an important role in reduction of cyanobacterial blooms (Kobayashi et al 2013 ). The precise phylogenetic positions of breviates and collodictyonids are not resolved, but molecular data suggest that they are one of the earliest divergences in eukaryotes (Katz et al 2011 ;Zhao et al 2012 ).…”

The free-living heterotrophic fl agellates are phylogenetically very diverse, and their phylogenetic diversity is nearly equal to that of all eukaryotes. They constitute the microbial loop together with bacteria and other protists, and play an indispensable and important role in aquatic ecosystems. However, their diversity has not been fully understood. In addition, recent environmental DNA studies suggest that there are many unidentifi ed heterotrophic fl agellate lineages in nature. This chapter describes the current knowledge on the diversity, biology and ecology of various groups of free-living heterotrophic fl agellates.
