Increasing intracellular trehalose is sufficient to confer desiccation tolerance to Saccharomyces cerevisiae [Genetics]

12-May-2015 | Hugo Tapia; Lindsey Young; Douglas Fox; Carolyn R. Bertozzi; Douglas Koshland, Proceedings of the National Academy of Sciences current issue, 2015

Diverse organisms capable of surviving desiccation, termed anhydrobiotes, include species from bacteria, yeast, plants, and invertebrates. However, most organisms are sensitive to desiccation, likely due to an assortment of different stresses such as protein misfolding and aggregation, ...

Coral symbiotic algae calcify ex hospite in partnership with bacteria [Environmental Sciences]

12-May-2015 | Jörg C. Frommlet; Maria L. Sousa; Artur Alves; Sandra I. Vieira; David J. Suggett; João Serôdio, Proceedings of the National Academy of Sciences current issue, 2015

Dinoflagellates of the genus Symbiodinium are commonly recognized as invertebrate endosymbionts that are of central importance for the functioning of coral reef ecosystems. However, the endosymbiotic phase within Symbiodinium life history is inherently tied to a more cryptic free-living (ex ...

The genome of cultivated sweet potato contains Agrobacterium T-DNAs with expressed genes: An example of a naturally transgenic food crop [Plant Biology]

05-May-2015 | Tina Kyndt; Dora Quispe; Hong Zhai; Robert Jarret; Marc Ghislain; Qingchang Liu; Godelieve Gheysen; Jan F. Kreuze, Proceedings of the National Academy of Sciences current issue, 2015

Agrobacterium rhizogenes and Agrobacterium tumefaciens are plant pathogenic bacteria capable of transferring DNA fragments [transfer DNA (T-DNA)] bearing functional genes into the host plant genome. This naturally occurring mechanism has been adapted by plant biotechnologists to develop ...

Continental-scale distributions of dust-associated bacteria and fungi [Environmental Sciences]

05-May-2015 | Albert Barberán; Joshua Ladau; Jonathan W. Leff; Katherine S. Pollard; Holly L. Menninger; Robert R. Dunn; Noah Fierer, Proceedings of the National Academy of Sciences current issue, 2015

It has been known for centuries that microorganisms are ubiquitous in the atmosphere, where they are capable of long-distance dispersal. Likewise, it is well-established that these airborne bacteria and fungi can have myriad effects on human health, as well as the health of plants and livestock. ...

Ominous projections for global antibiotic use in food-animal production [Agricultural Sciences]

05-May-2015 | Lance B. Price; Benjamin J. Koch; Bruce A. Hungate, Proceedings of the National Academy of Sciences current issue, 2015

Alexander Fleming famously warned that the ignorant may someday misuse his life-saving discovery—penicillin—and select for resistant bacteria (1). This was prescient given the widespread use of subtherapeutic antibiotics by food-animal producers today. According to the findings of Van Boeckel et ...

Global trends in antimicrobial use in food animals [Agricultural Sciences]

05-May-2015 | Thomas P. Van Boeckel; Charles Brower; Marius Gilbert; Bryan T. Grenfell; Simon A. Levin; Timothy P. Robinson; Aude ..., Proceedings of the National Academy of Sciences current issue, 2015

Demand for animal protein for human consumption is rising globally at an unprecedented rate. Modern animal production practices are associated with regular use of antimicrobials, potentially increasing selection pressure on bacteria to become resistant. Despite the significant potential ...

Inferring epigenetic dynamics from kin correlations [Physics]

05-May-2015 | Sahand Hormoz; Nicolas Desprat; Boris I. Shraiman, Proceedings of the National Academy of Sciences current issue, 2015

Populations of isogenic embryonic stem cells or clonal bacteria often exhibit extensive phenotypic heterogeneity that arises from intrinsic stochastic dynamics of cells. The phenotypic state of a cell can be transmitted epigenetically in cell division, leading to correlations in the states of ...

Mechanically-driven phase separation in a growing bacterial colony [Biophysics and Computational Biology]

28-Apr-2015 | Pushpita Ghosh; Jagannath Mondal; Eshel Ben-Jacob; Herbert Levine, Proceedings of the National Academy of Sciences current issue, 2015

Secretion of extracellular polymeric substances (EPSs) by growing bacteria is an integral part of forming biofilm-like structures. In such dense systems, mechanical interactions among the structural components can be expected to significantly contribute to morphological properties. Here, we use a ...

Microbial community transcriptional networks are conserved in three domains at ocean basin scales [Earth, Atmospheric, and Planetary Sciences]

28-Apr-2015 | Frank O. Aylward; John M. Eppley; Jason M. Smith; Francisco P. Chavez; Christopher A. Scholin; Edward F. DeLong, Proceedings of the National Academy of Sciences current issue, 2015

Planktonic microbial communities in the ocean are typically dominated by several cosmopolitan clades of Bacteria, Archaea, and Eukarya characterized by their ribosomal RNA gene phylogenies and genomic features. Although the environments these communities inhabit range from coastal to open ocean ...

Assaying the kinetics of protein denaturation catalyzed by AAA+ unfolding machines and proteases [Biochemistry]

28-Apr-2015 | Vladimir Baytshtok; Tania A. Baker; Robert T. Sauer, Proceedings of the National Academy of Sciences current issue, 2015

ATP-dependent molecular machines of the AAA+ superfamily unfold or remodel proteins in all cells. For example, AAA+ ClpX and ClpA hexamers collaborate with the self-compartmentalized ClpP peptidase to unfold and degrade specific proteins in bacteria and some eukaryotic organelles. Although ...
