Manure from dairy cows, which is commonly used as a farm soil fertilizer, contains a surprising number of newly identified antibiotic resistance genes from the cows' gut bacteria. The findings, reported in mBio® the online open-access journal of the American Society for Microbiology, hints that cow manure is a potential source of new types of antibiotic resistance genes that transfer to bacteria in the soils where food is grown. Thousands of antibiotic resistance (AR) genes have already...

Erin Weeks, Duke University Bumping sex cells with the hornworts may have done it During the age of the dinosaurs, the arrival of flowering plants as competitors could have spelled doom for the ancient fern lineage. Instead, ferns diversified and flourished under the new canopy -- using a mysterious gene that helped them adapt to low-light environments. A team led by Duke University scientists has pinpointed the curious origins of this gene and determined that it was transferred to...

Extreme Algae Thieves Its Genes From Bacteria

Brett Smith for redOrbit.com - Your Universe Online Some microorganisms have developed the ability to thrive in the most hostile environments on Earth, from the superheated geothermal vents to pools of toxic drainage deep underground. According to a new study in the journal Science, researchers have found evidence one of these so-called “extremophiles” steals its ability to endure extreme environments from the organisms around it. While the ability to pilfer genes from...

Scientists at the Academy of Finland's Centre of Excellence in Computational Inference Research have developed novel computational methods that have yielded essential knowledge of how hospital-acquired bacteria spread and develop. These new methods, based on randomised algorithms, make it possible to analyse extensive genomic data significantly faster and more efficiently than previously. By applying these results, it is possible to better follow hospital-acquired infections in the future, or...

Parasitic Plants Are Stealing Genes From Their Hosts

New research published today in BioMed Central's open access journal BMC Genomics reveals that the Malaysian parasitic plant Rafflesia cantleyi, with its 50cm diameter flowers, has 'stolen' genes from its host Tetrastigma rafflesiae. Analysis of these genes shows that their functions range from respiration to metabolism, and that some of them have even replaced the parasites own gene activity. Vertical gene transfer is that between parents and their offspring, while horizontal gene...

The evolution of plants and animals generally has been thought to occur through the passing of genes from parent to offspring and genetic modifications that happen along the way. But evolutionary biologists from Brown University and the University of Sheffield have documented another avenue, through the passing of genes from plant to plant between species with only a distant ancestral kinship. How this happened is unclear. But the researchers show that not only did a grouping of grasses...

• The study focuses on the protein Ler, which is present in the pathogenic strains of Escherichia coli that caused an outbreak of food poisoning in Germany last May. • Ler binds multiple DNA sequences, thereby activating numerous genes responsible for bacterial virulence. • The findings of the study have been published in PloS Pathogens. A team headed by scientists from the Institute for Research in Biomedicine (IRB Barcelona) reports how the protein Ler, which is...

Emergence of ENaC, sodium pump coincides with first appearance of multi-celled creatures Maintaining fluid balance in the body is essential to survival, from the tiniest protozoa to the mightiest of mammals. By researching recent genomic data, Swiss researchers have found genetic evidence that links this intricate process to a turning point in evolution. The study was led by Bernard Rossier, Professor Emeritus, University of Lausanne, along with colleagues Romain A. Studer, Emilie...

Bacteria more likely to adopt 'loner' genes than genes that are well-connected, study finds A new study of more than three dozen bacteria species "” including the microbes responsible for pneumonia, meningitis, stomach ulcers and plague "” settles a longstanding debate about why bacteria are more likely to steal some genes than others. While most organisms get their genes from their parents just like people do, bacteria and other single-celled creatures also regularly pick up...

Wolbachia is a genus of bacteria which infects arthropod species, including a high proportion of insects (~60% of species). It is one of the world's most common parasitic microbes and possibly the most common reproductive parasite in biosphere. Studies have suggested that 25-70% of all insect species are estimated to be potential hosts. Marshall Hertig and Burt Wolbach first identified the bacterium in 1924 in a species of mosquito. Hertig described the genus as Wolbachia pipientis. Not...
