Abstract

[Artikel-Nr.: 140] Background: Unicellular eukaryotes were widely considered to r eproduce without sex. However, recent findings suggest that meiosis, and by extension (sometimes cryptic) sexual reproduction, might be present in almost all eukaryotic lineages. Results: Here, we investigate the transcriptomic response underlying starvation-induced fusion in the Rhizaria protist Fisculla terrestris . Investigations of differentially expressed genes (DEGs) with a particular focus on the expression of meiosis-associated genes suggest that some form of meiosis and recombination might occur in these Rhizaria. Conclusions: We showed that starvation triggered changes in gene expression of meiosis-associated genes in F. terrestris . However, if these processes are coupled with sexual reproduction remains to be investigated.
