Robin Gasser and his colleagues report the whole-genome sequence of Schistosoma haematobium. They include comparisons to the genome sequences of S. mansoni and S. japonicum, the two other species that cause schistosomiasis in humans.
Joy Bergelson and colleagues characterize genome-wide patterns of genetic variation in a collection of 1,307 worldwide Arabidopsis thaliana accessions from the Regional Mapping (RegMap) panel, a publicly available genomic resource that includes large regional panels. They characterize signatures of selection and patterns of recombination and identify an enrichment of hotspots in intergenic regions and in repetitive DNA.
Huda Zoghbi and colleagues report that MECP2 transgenic mice display heightened anxiety and social approach deficits and that genetic and pharmacological inhibition of Crh or its receptor, Crhr1, suppresses the anxiety phenotypes. The authors also report that genetic reduction of Oprm1 improves social approach behaviors in MECP2 transgenic mice.
