Distinct light-, stress-, and nutrient-dependent regulation of multiple tryptophan-rich sensory protein (TSPO) genes in the cyanobacterium Fremyella diplosiphon.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The cyanobacterium Fremyella diplosiphon possesses 3 genes encoding homologs of the tryptophan-rich sensory protein (TSPO). TSPO proteins are membrane proteins implicated in stress responses across a range of organisms from bacteria to humans. Diverse TSPO proteins appear to generally bind tetrapyrrole ligands. Previously, we reported that one of these homologs, FdTSPO1, is involved in salt-, osmotic- and oxidative stress responses in F. diplosiphon. Here, we show distinct regulation of cellular mRNA levels of all 3 FdTSPO homologs by different abiotic stresses. Given the prior finding that all 3 FdTSPO proteins are capable of binding tetrapyrroles of functional relevance in F. diplosiphon and the observation of a ligand-dependent functional role for FdTSPO1 in vivo, FdTSPO1, FdTSPO2, and FdTSPO3 appear to have distinct, yet overlapping, roles in vivo. We propose that these proteins regulate tetrapyrrole homeostasis and/or tetrapyrrole-modulated functions in F. diplosiphon in response to multiple environmental stresses.
