RNA-seq of Chlamydomonas reinhardtii under diel conditions to identify cycling genes

ABSTRACT: Biological rhythms in response to both endogenous (circadian) and exogenous (e.g. diel) cycles, with a period of ~24 hours, are a prominent feature of many living systems. In green algal species, knowledge on the extent of diel rhythmicity of genome wide gene expression, its evolution, and its cis-regulatory mechanism is limited. In this study, we identified cyclically expressed genes under diel conditions in Chlamydomonas reinhardtii and found that ~50% of the 17,114 annotated genes exhibited cyclic expression. The cyclic expression patterns indicate a clear succession of biological processes during the course of a day. Among 237 functional categories enriched in cyclically expressed genes, >90% were phase-specific, including photosynthesis, cell division and motility processes. By contra
