Long Non-Coding RNAs in the Control of Gametogenesis: Lessons from Fission Yeast

Long non-coding RNAs (lncRNAs) contribute to cell fate decisions by modulating genome expression and stability. In the fission yeast Schizosaccharomyces pombe, the transition from mitosis to meiosis results in a marked remodeling of gene expression profiles, which ultimately ensures gamete production and inheritance of genetic information to the offspring. This key developmental process involves a set of dedicated lncRNAs that shape cell cycle-dependent transcriptomes through a variety of mechanisms, including epigenetic modifications and the modulation of transcription, post-transcriptional and post-translational regulations, and that contribute to meiosis-specific chromosomal events. In this review, we summarize the biology of these lncRNAs, from their identification to mechanism of action, and discuss their regulatory role in the control of gametogenesis.

Long non-coding RNAs play a role in cell fate decisions by modulating genome expression and stability. In the fission yeast, specific lncRNAs shape cell cycle-dependent transcriptomes, influencing gametogenesis and contributing to meiosis-specific chromosomal events.
