Scientists at the Oklahoma Medical Research Foundation studying neurons in Caenorhabditis elegans have found a gene, unc-16, that serves as a gatekeeper, restricting the flow of specific membrane-enclosed organelles from the cell body to the axon. Organelles clogging the axon could potentially interfere with neuronal signaling or cause the axon to degenerate, leading to neurodegenerative disorders.
Kansas State University researcher Bikram Gill is part of an international team of researchers that developed a physical map of wheat’s wild ancestor, Aegilops tauschii, commonly called goatgrass. It's the first huge step toward sequencing the wheat genome – a complete look at wheat’s genetic matter. The work, which has been published in the April 22 edition of the Proceedings of the National Academy of Sciences (PNAS), showed among other things, that most resistance genes seem to lie at the ends of chromosomes and can be easily accessed. The findings can lead to breeding of more productive and sustainable wheat varieties.

In a pair of papers published in PLOS Genetics, two diverse teams of scientists, both headed by researchers at the University of California, San Diego School of Medicine, describe novel statistical models that more broadly and deeply identify associations between bits of sequenced DNA called single nucleotide polymorphisms or SNPs and say lead to a more complete and accurate understanding of the genetic underpinnings of many diseases and how best to treat them.
Your genetic makeup can help determine how well your body will respond to weight loss efforts aimed at controlling high blood pressure, a new study confirms. The multi-institutional study, led by researchers at The Cardiovascular Institute, part of the University of Medicine and Dentistry of New Jersey-Robert Wood Johnson Medical School, may help clarify how hypertension develops and progresses in certain individuals and also identify people for whom weight loss programs are most likely to help reduce blood pressure.

New research suggests that fainting may be genetic and, in some families, only one gene may be responsible. However, a predisposition to certain triggers, such as emotional distress or the sight of blood, may not be inherited. The study is published in the April 16, 2013, print issue of Neurology®, the medical journal of the American Academy of Neurology. Fainting, also called vasovagal syncope, is a brief loss of consciousness when your body reacts to certain triggers. It affects at least one out of four people.
Scientists at Washington University School of Medicine in St. Louis and elsewhere have decoded the genome of the platyfish, a cousin of the guppy and a popular choice for home aquariums.
