Abstract:
Cyclic di-GMP signaling regulates sessile-to-motile lifestyle transition and associated physiological and metabolic features in bacteria. The presence of potential cyclic di-GMP turnover proteins in deepest branching bacteria indicates that cyclic di-GMP is an ancient signaling molecule. In this issue of The EMBO Journal, Cai et al (2023) describe light-induced activation of a thiosulfate oxidation pathway in the deep-sea cold-seep bacterium Qipengyuania flava, thus coupling cyclic di-GMP with the regulation of the global abiotic sulfur cycle.

Testing a Claim about Mean: Known Population SD
Estimating a population mean requires the samples to be distributed normally. The data should be collected from the randomly selected samples having no sampling bias. The sample size needed to be higher than 30, and most importantly, the population standard deviation should be already known.
In most realistic situations, the population standard deviation is often unknown, but in rare circumstances, when it...
