During Zerfall, a phase of extreme endoreplication, the transcriptome is largely silenced with the exception of gene families involved in genome processes and stability. Intriguingly, these gene families include chromatin modifiers, spliceosomal components and histone paralogs, some of which are known to contribute to cell type differentiation in multicellular eukaryotes. We also find numerous genes involved in DNA repair (e.g. DNA damage response and R-loop regulating genes). We speculate that these genes are part of an ancient eukaryotic toolkit, likely present in the last eukaryotic common ancestor (LECA) and that regulates genomes during life cycle transitions. Our method, Pheno2Seq, can be adapted to diverse lineages to enable the study of life cycle regulation in microeukaryotes that lack morphologically distinguishable life cycle stages. ]]> 2026-10-23
