ABSTRACT Virus induced gene silencing (VIGS) is an efficient technique to quickly evaluate gene functions. VIGS utilizes the mechanism(s) of RNA interference (RNAi), which the virus vector carrying the gene of interest will be silenced through posttranscriptional gene silencing. Agrobacterium is used to carry the constructed vectors to infect the plants . Here, I summarized several inoculation methods have been reported recently to infect the plants. We are working on evaluating the efficiency with these different methods in our study system. Our lab uses Nicotiana obtusifolia (desert tobacco) as a model to studygene regulating plant development. I report the result …

Background
The fruit fly Drosophila melanogaster has been used extensively to investigate genetic mechanisms of ethanol-related behaviors. Many past studies in flies, including studies from our laboratory, have manipulated gene expression using transposons carrying the genetic-phenotypic marker mini-white, a derivative of the endogenous gene white. Whether the mini-white transgenic marker or the endogenous white gene influence behavioral responses to acute ethanol exposure in flies has not been systematically investigated.
Methods
We manipulated mini-white and white expression via (i) transposons marked with mini-white, (ii) RNAi against mini-white and white and (iii) a null allele of white. We assessed ethanol sensitivity and …

Identifying Functional Variation In Schizophrenia Gwas Loci By Pooled Sequencing, Erik Loken
Theses and Dissertations
Schizophrenia demonstrates high heritability in part accounted for by common simple nucleotide variants (SNV), rare copy number variants (CNV) and, most recently, rare SNVs Although heritability explained by rare SNVs and CNVs is small compared to that explained by common SNVs, rare SNVs in functional sequences may identify specific disease mechanisms. However, current exome methods do not capture a large proportion of potentially functional bases where rare variation may impact disease risk: as much as two-thirds of conserved sequences lie outside the exome in non-coding regions of cross-species evolutionary constraint. We reasoned that the candidate loci from the Psychiatric Genomics …
