It was shown that the identification of S. marcescens isolates by biochemical testing, mass spectrometry or 16S rRNA gene sequencing was insufficient to resolve the ‘S. marcescens complex’, while sampling point analysis revealed that many genomes assigned to the S.

Abstract Light as a substrate for photosynthesis may be a boon or a bane. To thrive, photosynthetic organisms must constantly respond to changing light and CO2 conditions by balancing energy harvest and consumption in a highly dynamic way. Two major safeguard measures of photoacclimation, that is photoprotection and carbon concentrating mechanism, underlie tight transcriptional control, leading to expression changes under high light and limited CO2 with different dynamics for both systems.
