Project description:We assembled and characterized the genetic diversity of a representative collection of Ethiopian teff (Eragrostis tef) genotypes developed from landraces and breeding materials.
Project description:Understanding how DNA sequence variation is translated into variation for complex phenotypes has remained elusive, but is essential for predicting adaptive evolution, selecting agriculturally important animals and crops, and personalized medicine. Here, we quantified genome-wide genetic variation in gene expression in the sequenced inbred lines of the Drosophila melanogaster Genetic Reference Panel. We found that a substantial fraction of the Drosophila transcriptome is genetically variable and organized into modules of genetically correlated transcripts, which provide functional context for newly identified novel transcribed regions. We identified regulatory variants for the mean and variance of gene expression, both of which showed oligogenic genetic architecture. Expression quantitative trait loci the mean, but not the variance, of gene expression were concentrated near genes. This comprehensive characterization of transcriptomic diversity and its genetic basis in the DGRP is critically important for a systems understanding of quantitative trait variation.
Project description:Identify genes in the epididymal adipose tissue whose expression is under genetic regulation in the hybrid mouse diversity panel. The hybrid mouse diversity panel is comprised of classical inbred and recombinant inbred wild type mice. The RMA values of genes were used for genome wide association as described in Bennett et al Genome Research 2010. These data are used to identify candidate genes at loci associated with obesity and dietary responsiveness. GWAS for expression of epididymal adipose tissue in inbred strains
Project description:Identify genes in the heart whose expressions under genetic regulation in the hybrid mouse diversity panel. The hybrid mouse diversity panel is comprised of classical inbred and recombinant inbred wild type mice. The RMA values of genes were used for genome wide association as described in Bennett et al Genome Research 2010. These data used to identify candidate genes at loci associated with atherosclerosis.

Project description:Local breeds retained unique genetic variability important for adaptive potential especially in light of challenges related to climate change. Our objective was to perform, for the first time, a genome-wide diversity characterization using Illumina GoatSNP50 BeadChip of autochthonous Drežnica goat breed from Slovenia. Genetic diversity analyses revealed that the Slovenian Drežnica goat has a distinct genetic identity and is closely related to the neighboring Austrian and Italian alpine breeds. These results expand our knowledge on phylogeny of goat breeds from easternmost part of the European Alps.
