\n\t\tBiology professor awarded $2.5 million NSF grant<\/b> <\/p>\n


\n\tKINGSTON, R.I. \u2013 October 2, 2015 \u2013 A 溏心vlog免费B站 biologist has been awarded a $2.5 million grant from the National Science Foundation to study the genetics of three groups of parasites and single-celled organisms to help scientists complete a detailed tree of life of Earth\u2019s living organisms.<\/p>\n


\n\tThe grant to Christopher Lane, associate professor of biological sciences, is part of NSF\u2019s Genealogy of Life program, which is examining the evolutionary patterns and processes of life on Earth.<\/p>\n


\n\t\u201cThere are lots of areas of the tree of life that we know very little about,\u201d said Lane, who joined the 溏心vlog免费B站 faculty in 2008 and studies marine biodiversity and comparative genomics. \u201cWe don\u2019t know a lot about what\u2019s at the base of the tree of life, for instance, and what major groups belong together. To figure that out, we\u2019ve got to collect more data from areas of the tree that we don\u2019t understand well.\u201d<\/p>\n


\n\tLane, his students, and colleagues at the University of Maryland and Smith College, will focus their work on the stramenopiles, which include diatoms, brown algae and water molds; the rhizaria, single-celled marine and aquatic organisms that serve as decomposers and predators on the micro scale; and the alveolata, a group of more than 6,000 single-celled parasites, ciliates and dinoflagellates.<\/p>\n


\n\t\u201cThese three groups are responsible for an enormous amount of ecosystem functioning that we don\u2019t appreciate or fully recognize,\u201d Lane said. \u201cMany are having huge impacts on food webs, both marine and terrestrial, and we know very little about what they do and who they are. Our job will be to get a whole bunch of genetic information from these organisms to place them in the tree of life and understand their role in the ecosystem.\u201d<\/p>\n


\n\tThe researchers will examine organisms in existing databases and collect new samples from freshwater, saltwater and terrestrial sites from a wide variety of habitats around the world. They will then sequence a short region of DNA from each member of the organisms they are targeting.<\/p>\n


\n\t\u201cThat will give us an idea of what\u2019s there or what the diversity is of those different groups in those environments,\u201d said Lane, a resident of North Kingstown. \u201cFrom that we\u2019ll be able to tell which environments we need to explore more.\u201d<\/p>\n


\n\tAccording to Lane, gaps in the tree of life may create biases in the data that scientists use to understand the evolutionary relationships among species. A great deal more is known about plants and animals, for instance, than most other species groups, resulting in an over-representation of plants and animals in data sets.<\/p>\n


\n\t\u201cWe\u2019re trying to understand our living world and the evolution of organisms through time,\u201d he said. \u201cBut there have been some significant changes in the past 15 years that completely change how we understand the evolution of some traits. <\/p>\n


\n\u201cAnd major groups of organisms we never knew existed have just shown up on our radar,\u201d he added. \u201cWe know them by their genetic signature, but we don\u2019t know what they look like or what they consume or how they make a living. So part of this project is trying to flesh out that information.\u201d<\/p>\n


\n\tThe five-year research project will result in the creation of about 250 draft genomes, thousands of new DNA barcodes, and numerous images of organisms that will be deposited in online databases for scientists to use in future studies, including predictive modeling of the future evolution of life on Earth.<\/p>\n


\n\t\u201cGroups all over the world are patching in pieces of the tree of life,\u201d Lane concluded. \u201cWe play a small role, because it\u2019s impossible to play a big role in such a huge project. We\u2019re just doing our part.\u201d<\/div>\n","protected":false},"excerpt":{"rendered":"
