In desert ecosystems, microbial activity is driven by brief hydration pulses but is severely limited by persistent nutrient scarcity. Cyanobacteria...

The Great Barrier Reef Microbial Genomes Database compiles prokaryotic, viral and eukaryotic genomes from seawater collected from the Great Barrier Reef, providing a rich resource for the study of mar...

Abstract. Transcriptional interference is rarely documented in bacteria. In cyanobacteria, phycobilisomes are the major light-harvesting antennae, and thei

Guanidine is well known as a denaturing agent. However, recent studies have demonstrated both the widespread synthesis of guanidine, e.g., in plant...

Nature Communications - RNA-binding proteins play key roles in post-transcriptional gene regulation. Here, Hemm et al. developed RAPDOR, a widely applicable tool based on Jensen-Shannon Distance...

Cyanobacterial growth depends on inorganic carbon (Ci; CO2 and bicarbonate) concentration, but mechanism(s) adjusting photosynthesis and growth according to Ci remain unclear. ΔrpoZ cells lacking th...

Oxygenic photosynthesis in streptophytic algae, such as Charophyceae, is often impeded by low CO2 levels in aquatic habitats. Consequently, many algal groups evolved a CO2-concentrating mechanism (C...

RNA-guided systems provide remarkable versatility, enabling diverse biological functions. Through iterative structural and sequence homology-based mining starting with a guide RNA-interaction domain o...

During their evolution from cyanobacteria, plastids have relinquished most of their genes to the host cell nucleus, but have retained a core set of ge…

Motility in Archaea is driven by a nanomachinery called the archaellum. So far, archaella have been exclusively described for the archaeal domain; however, a recent study reported the presence of arch...

Single-cell decisions made in complex environments underlie many bacterial phenomena. Image-based transcriptomics approaches offer an avenue to study such behaviors, yet these approaches have been hin...

SUMMARYThe development of multicellularity represents a key evolutionary transition that is crucial for the emergence of complex life forms. Although multicellularity has traditionally been studied in...

Using a deep neural network and statistical analyses of atomic force microscopy images of individual RNA molecules enables the mapping of RNA conformational space in solution.

Abstract. RNA-binding proteins (RBPs) are central components of gene regulatory networks. The differentiation of heterocysts in filamentous cyanobacteria i

Cyanobacteria are powered by oxygenic photosynthesis located in extensive internal membrane systems, the thylakoids. Using carboxysomes, they assimilate organic from inorganic carbon. The integration...

Horizontal gene transfer, the asymmetric movement of genetic information between donor and recipient organisms, is an important mechanism for acquiring new traits. In order for newly acquired gene content to be retained, it must be integrated into the ...

Abstract. Epigenetic DNA modifications are pivotal in eukaryotic gene expression, but their regulatory significance in bacteria is less understood. In Syne

Abstract. Even though Bacillus subtilis is one of the most studied organisms, no function has been identified for about 20% of its proteins. Among these un

Throughout the tree of life RNA-binding proteins play important roles, but they are poorly characterized in cyanobacteria. Overexpression of the predicted RNA-binding protein Ssr1238 in the cyanoba...
