Article of the Month

Coated films are widely used to protect food, electronic devices and other goods from air and moisture, but the performance of such films is influenced by numerous parameters, including temperature, humidity and exposure to light. In January's article of the month, Kiese et al. determine how temperature influences the transport of water through a plastic film (polyethylene terephthalate) coated with inorganic-organic hybrid polymers and silicon dioxide in different multilayer configurations. They developed equations to predict the behavior of the individual layers and composite films before verifying the predictions experimentally. The temperature dependence of steady-state permeation was found to depend mainly on the silicon dioxide layer, whereas the hybrid polymer layer determined the lag time for vapor transmission. The results can be used to predict the performance of barrier films in different environments, allowing the most appropriate coated films to be selected for a given purpose.

Pathogens diversify as they spread, resulting in a range of variant strains differing in host specificity, virulence and biochemical properties. This is the case for Pseudomonas syringae, a bacterial phytopathogen that exists as more than 50 different pathovars defined according to their pathogenicity on different host plants. Within each pathovar, there may be multiple biovars with varying degrees of virulence. It is important to understand how the virulence of different pathovars and biovars is controlled in order to develop suitable countermeasures. In December's article of the month, Vandelle et al. describe a new whole-genome microarray that can characterize different biovars of Pseudomonas syringae pv. actinidiae and identify the molecular basis of their differing virulence. Psa3, the most aggressive biovar, showed a rapid and extreme reaction to the plant apoplast, establishing virulence before the plant was able to mount an effective defense response. Identifying the specific signaling molecules involved could facilitate the development of new strategies to prevent or control plant diseases.

Species that have evolved to deal effectively with pathogens offer a potential rich source of new antimicrobial drugs. Social insects such as termites fall into this category because they live in colonies that consist of large numbers of individuals living in close contact with each other (and with their food and nesting material), an ideal environment for diseases to spread. Termites carry beneficial microbes that help to prevent the spread of pathogens in the colony, and the investigation of these microbes could provide a source of new antibiotics for humans. In November's article of the month, Oberpaul et al. describe the systematic analysis of the core microbiome at different nest levels for three species of termites, enriching for the underrepresented microbes to find out more about the microbial community and their contribution to colony fitness. The more we learn about the microbes associated with social insects, the closer we come to finding out how they inhibit pathogens and how we can use them to produce new antimicrobial drugs.
