The transition to the aggregative stage of Capsaspora owczarzaki, a close unicellular relative to Metazoa, is associated with significant upregulation of orthologs of genes that are important for multicellularity in metazoans.
The foundations of genomic complexity in multicellular animals have deep roots in their unicellular prehistory, both in terms of innovations in gene content, as well as the evolutionary dynamics of genome architecture.
The complex chromatin-based genomic regulatory system controlling developmental gene expression in complex bilaterians predates the evolution of morphological complexity and may have been a prerequisite for the evolution of the first simple multicellular animals.
The convergent evolution of yeast Mim1/2 and trypanosomal pATOM36 enable the first demonstration of reciprocal functional rescue of two evolutionary unrelated mitochondrial biogenesis complexes belonging to two different eukaryotic supergroups.
Newly discovered interaction between fission yeast SPB and animal centriole components reveals that pericentrin not only functions as a microtubule-nucleator, but also promotes centriole assembly in animals.
