Daily rhythmicity in coastal microbial mats

Photosynthetically active radiation during the sampling period (A) and peak expression phases of rhythmic CGTs in the metatranscriptome (b). a Photosynthetically active radiation (PAR) (μmol？m？2？s？1) measured every minute during the sampling period on the beach of Schiermonnikoog (N？=？1429). Stippled lines indicate sampling time of metatranscriptomes (N？=？6). b Clustered bar chart plots the peak expression F(h) against the count of rhythmic protein-coding CGTs. CGT-F (forward reads)？=？black, CGT-R (reverse reads)？=？gray. The peak expression phase displays the time frame in which gene expression reaches maximu
