Evidence Snippets

SliP4 is a small, 37 amino acids protein that is strongly induced when the cyanobacterium Synechocystis sp. PCC 6803 is exposed to high-light (HL) conditions.

Claim 1expression inductionsupports2026Source 1DOI PubMed

SliP4 is a 37-amino-acid protein that is strongly induced under high-light conditions in Synechocystis sp. PCC 6803.

Claim 2interpretive mechanismsupports2026Source 1DOI PubMed

Synechocystis compensates for loss of SliP4 by activating a genetic program for a population-level response that helps cells cope with high-light conditions.

Claim 3metabolic changesupports2026Source 1DOI PubMed

Metabolome analysis suggested altered nitrogen and carbon metabolism in sliP4 mutant cells compared with wild type.

Claim 4omics observationsupports2026Source 1DOI PubMed

Proteome analysis showed consistent expression changes in many high-light-regulated proteins in the sliP4 mutant.

Claim 5phenotype associationsupports2026Source 1DOI PubMed

Deletion of sliP4 causes a light-sensitive phenotype associated with impaired cyclic electron flow and state transitions.

Claim 6population level responsesupports2026Source 1DOI PubMed

The sliP4 mutant increases extracellular polysaccharide production and aggregates after a high-light shift, corresponding to upregulated xssA-E and xssN-P expression for synechan production.

Claim 7regulatory responsesupports2026Source 1DOI PubMed

The sliP4 mutant shows a wild-type-like gene regulatory response 30 minutes after a high-light shift from 50 to 250 bcmol photons m2 s1, and this response is controlled by the RpaB-PsrR1 system.
