#1
REVIEW
Lisa B Wiltbank, David M Kehoe
Cyanobacteria are an evolutionarily and ecologically important group of prokaryotes. They exist in diverse habitats, ranging from hot springs and deserts to glaciers and the open ocean. The range of environments that they inhabit can be attributed in part to their ability to sense and respond to changing environmental conditions. As photosynthetic organisms, one of the most crucial parameters for cyanobacteria to monitor is light. Cyanobacteria can sense various wavelengths of light and many possess a range of bilin-binding photoreceptors belonging to the phytochrome superfamily...

REVIEW
Masanori Toyofuku, Nobuhiko Nomura, Leo Eberl
Most bacteria release membrane vesicles (MVs) that contain specific cargo molecules and have diverse functions, including the transport of virulence factors, DNA transfer, interception of bacteriophages, antibiotics and eukaryotic host defence factors, cell detoxification and bacterial communication. MVs not only are abundant in nature but also show great promise for applications in biomedicine and nanotechnology. MVs were first discovered to originate from controlled blebbing of the outer membrane of Gram-negative bacteria and are therefore often called outer-membrane vesicles (OMVs)...

#3
REVIEW
Zhenzhong Yu, Reinhard Fischer
Light controls important physiological and morphological responses in fungi. Fungi can sense near-ultraviolet, blue, green, red and far-red light using up to 11 photoreceptors and signalling cascades to control a large proportion of the genome and thereby adapt to environmental conditions. The blue-light photoreceptor functions directly as a transcriptional regulator in the nucleus, whereas the red-light-sensing and far-red-light-sensing phytochrome induces a signalling pathway to transduce the signal from the cytoplasm to the nucleus...

REVIEW
Jun-Hong Ch'ng, Kelvin K L Chong, Ling Ning Lam, Jun Jie Wong, Kimberly A Kline
Enterococci are ubiquitous members of the human gut microbiota and frequent causes of biofilm-associated opportunistic infections. Enterococci cause 25% of all catheter-associated urinary tract infections, are frequently isolated in wounds and are increasingly found in infective endocarditis, and all of these infections are associated with biofilms. Enterococcal biofilms are intrinsically tolerant to antimicrobials and thus are a serious impediment for treating infections. In this Review, we describe the spatiotemporal development of enterococcal biofilms and the factors that promote or inhibit biofilm formation...

Antimicrobial susceptibility testing (AST) technologies help to accelerate the initiation of targeted antimicrobial therapy for patients with infections and could potentially extend the lifespan of current narrow-spectrum antimicrobials. Although conceptually new and rapid AST technologies have been described, including new phenotyping methods, digital imaging and genomic approaches, there is no single major, or broadly accepted, technological breakthrough that leads the field of rapid AST platform development...

REVIEW
Richard J Lamont, Hyun Koo, George Hajishengallis
The dynamic and polymicrobial oral microbiome is a direct precursor of diseases such as dental caries and periodontitis, two of the most prevalent microbially induced disorders worldwide. Distinct microenvironments at oral barriers harbour unique microbial communities, which are regulated through sophisticated signalling systems and by host and environmental factors. The collective function of microbial communities is a major driver of homeostasis or dysbiosis and ultimately health or disease. Despite different aetiologies, periodontitis and caries are each driven by a feedforward loop between the microbiota and host factors (inflammation and dietary sugars, respectively) that favours the emergence and persistence of dysbiosis...

In Figure  3, 'Candidatus Scalindua' and Thaumarchaeota were erroneously shown to produce nitrous oxide (N2 O). As neither group directly produces N2 O, the arrows and products have been removed both online and in the pdf. The authors apologize for any confusion caused.

REVIEW
Anthony D Bertagnolli, Frank J Stewart
In the ocean's major oxygen minimum zones (OMZs), oxygen is effectively absent from sea water and life is dominated by microorganisms that use chemicals other than oxygen for respiration. Recent studies that combine advanced genomic and chemical detection methods are delineating the different metabolic niches that microorganisms can occupy in OMZs. Understanding these niches, the microorganisms that inhabit them, and their influence on marine biogeochemical cycles is crucial as OMZs expand with increasing seawater temperatures...
