Emergence of metabolic coupling to the heterotroph Alteromonas promotes dark survival in Prochlorococcus

The paper shows that Prochlorococcus develops a dark-tolerant phenotype when co-cultured with Alteromonas, involving metabolic coupling and shifts in gene expression.

Control of a type III-Dv CRISPR-Cas system by the transcription factor RpaB and interaction of its leader transcript with the DEAD-box RNA helicase CrhR

This study identifies RpaB as a light-and redox-responsive transcription factor regulating a type III-Dv CRISPR-Cas system in Synechocystis sp. PCC 6803 and shows CrhR interacts with the leader transcript posttranscriptionally.

The role of the 5' sensing function of ribonuclease E in cyanobacteria

This study investigates the role of 5' sensing in RNase E of Synechocystis, identifying cleavage sites and demonstrating its impact on rRNA, tRNA maturation, and plasmid copy number.

Regulation of pSYSA defense plasmid copy number in Synechocystis through RNase E and a highly transcribed asRNA

The paper identifies a regulatory mechanism for pSYSA plasmid copy number in Synechocystis involving RNase E and an antisense RNA, revealing a novel replication system with implications for synthetic biology.

Feedback regulation of RNase E during UV-stress response in the cyanobacterium Synechocystis sp. PCC 6803

The paper investigates RNase E feedback regulation in Synechocystis sp. PCC 6803 under UV stress, finding increased enzymatic activity and stabilized rne mRNA via 5' UTR autoregulation.

Transcriptome-wide in vivo mapping of cleavage sites for the compact cyanobacterial ribonuclease E reveals insights into its function and substrate recognition

The paper maps RNase E cleavage sites in Synechocystis sp. PCC 6803 using TIER-seq, revealing cleavage signatures and regulatory roles of RNase E and RNase J.

The temperature-regulated DEAD-box RNA helicase CrhR interactome: Autoregulation and photosynthesis-related transcripts

This study identifies the RNA interactome of the cyanobacterial DEAD-box helicase CrhR, revealing its role in photosynthesis and redox regulation through auto-regulation and binding of photosynthesis-related transcripts.

Discovery of a novel small protein factor involved in the coordinated degradation of phycobilisomes in cyanobacteria

The paper identifies NblD, a small protein essential for phycobilisome degradation in cyanobacteria during nitrogen starvation, showing it interacts with β-phycocyanin and is required for coordinated dismantling.
