SUMMARY Multicellular organization arose several times by convergence during the evolution of eukaryotes (e.g., in terrestrial plants, several lineages of “algae,” fungi, and metazoans). To reconstruct the evolutionary transitions between unicellularity and multicellularity, we need a proper understanding of the origin and diversification of regulatory molecules governing the construction of a multicellular organism in these various lineages. Homeodomain (HD) proteins offer a paradigm for… 
The diversification of the basic leucine zipper family in eukaryotes correlates with the evolution of multicellularity
TLDR
The results reveal the ancestral opisthokont, holozoan and metazoan bZIP repertoire and provide insights into the progressive expansion and divergence of b ZIPs in the five main eukaryotic kingdoms, suggesting that the early diversification of bZips in multiple eukARYotic lineages was a prerequisite for the evolution of complex multicellular organisms.
Transcription Factors and the Origin of Animal Multicellularity
TLDR
This chapter describes the changes that led to the establishment of gene regulatory networks that control animal multicellularity and review different case-examples that have provided illuminating insights into this question.
Genesis and expansion of metazoan transcription factor gene classes.
TLDR
Transcription factor orthologues present in sponge, cnidarian, and bilaterian genomes may represent part of the core metazoan regulatory network underlying the origin of animal development and multicellularity.
Unexpected repertoire of metazoan transcription factors in the unicellular holozoan Capsaspora owczarzaki.
TLDR
The repertoire of 17 metazoan TFs is uncovered in the amoeboid holozoan Capsaspora owczarzaki, a representative of a unicellular lineage that is closely related to choanoflagellates and metazoans, and new hypotheses regarding the origin and evolution of developmental metazoa TFs are formulated.
Early evolution of metazoan transcription factors.
Homeodomain subtypes and functional diversity.
TLDR
Homeobox genes perform key roles for all aspects of the development of an organism, and several particular types of homeodomain proteins play roles in the determination of cell fates and cell differentiation.
The Evolution of the GPCR Signaling System in Eukaryotes: Modularity, Conservation, and the Transition to Metazoan Multicellularity
TLDR
Using eukaryotic genomes covering most lineages sampled to date, it is found that the various components of the GPCR signaling pathway evolved independently, highlighting the modular nature of this system.
Origins and Evolution of WUSCHEL-Related Homeobox Protein Family in Plant Kingdom
TLDR
Insight is provided into the origin and evolutionary process of WOXs, facilitating their functional investigations in the future and among the members of Arabidopsis thaliana and Oryza sativa, the authors observed ubiquitous expression of genes in the first clade and the diversified expression pattern of Wox genes in distinct organs in the second clades.

Did homeodomain proteins duplicate before the origin of angiosperms, fungi, and metazoa?
TLDR
The hypothesis that there was at least one duplication of homeobox genes before the origin of angiosperms, fungi, and metazoa is supported and suggests that these proteins had diverse functions early in the evolution of eukaryotes.
The Homeodomain: An Ancient Evolutionary Motif in Animals and Plants
Molecular evolution of the homeodomain family of transcription factors.
TLDR
The phylogenetic analysis, coupled with the chromosomal localization of these genes, provides powerful clues as to how each of these classes arose from the ancestral homeodomain.
The last universal common ancestor (LUCA), simple or complex?
TLDR
The relationships between present-day prokaryotes and the ancestral eukaryotic lineage (those which existed before the LUCA) are thought to be more complex than previously thought.
Evolutionary change of the numbers of homeobox genes in bilateral animals.
TLDR
It is concluded that both gain and loss of homeobox genes were important for the evolutionary change of phenotypic characters in bilateral animals.
The genome reduction hypothesis and the phylogeny of eukaryotes.
Genome reduction in prokaryotic obligatory intracellular parasites of humans: a comparative analysis.
TLDR
Comparative analyses of five completely sequenced obligatory intracellular parasite genomes reveal that these genomes display marked similarities in patterns of protein length and frequency distribution, with substantial sharing of a 'backbone genome'.

TLDR
Early eukaryotic gene structures were very complex, and that simplification, not embellishment, has dominated subsequent evolution, and intron losses outnumber gains over a large range of eUKaryotic lineages.
Phylogeny of Choanozoa, Apusozoa, and Other Protozoa and Early Eukaryote Megaevolution
TLDR
The taxon-rich rRNA phylogeny for eukaryotes allowing for intersite rate variation strongly supports the opisthokont clade and agrees with the view that Choanozoa are sisters of or ancestral to animals and reveals a novel nonflagellate choanozoan lineage, Ministeriida, sister either to choanoflagellates, traditionally considered animal ancestors, or to animals.
