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.
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.
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.
单细胞真核生物曾被广泛认为是无性繁殖的。然而，最近的研究结果表明，减数分裂以及由此延伸的（有时是隐秘的）有性生殖可能存在于几乎所有真核生物谱系中。
在这里，我们研究了根足虫类原生生物陆地盘菌（Fisculla terrestris）饥饿诱导融合背后的转录组反应。对差异表达基因（DEGs）的研究，特别关注减数分裂相关基因的表达，表明这些根足虫类可能会发生某种形式的减数分裂和重组。
我们表明饥饿触发了陆地盘菌减数分裂相关基因的表达变化。然而，这些过程是否与有性生殖相关仍有待研究。
