Project description:Genotyping by sequencing data from Siberian Larix individuals
Project description:The goal of this experiment is to evaluate the potential for utilising this oligonucleotide microarray in other species and genera of the Pinaceae family by using comparative RNA hybridizations in four different spruces (Picea spp), two pines (Pinus spp.) and a larch (Larix laricina), across two tissues, xylem and phelloderm.
Project description:We measured transcriptional profiles of individuals of Andropogon gerardii, a C4 grass native to North American grasslands, in a field experiment in which both temperature and precipitation have been manipulated to simulate key aspects of forecasted climate change.

Project description:Array CGH analysis of Helicobacter pylori strains isolated from a North American cohort of symptomatic pediatric patients. Keywords: genotyping_design A genotyping experiment design type classifies an individual or group of individuals on the basis of alleles, haplotypes, SNP's. Patients enrolled under Benjamin Gold's Emory IRB protocol. Initial strain isolation from antral biopsies performed at Emory and culture sweeps sent to FHCRC (Seattle) for analysis. Single colony isolates (4) from each patient antral biopsy were isolated and profiled using RAPD. A single clone of each RAPD type detected in each patient (1-2) were analyzed on duplicate arrays. For analysis 500 ng of genomic DNA of each test strain was labeled with Cy5 and 500 ng of genomic DNA of a reference sample (equimolar mix of 26695 and J99) was labeled with Cy3. Strains identified as Em-patient#-clone#.
Project description:Purpose: The goal of the current study was to find the candidate genes responsible for the habita specific clock variation in N. discreta. Methods: We performed RNA-seq experiment using four strains ; African parent (FGSC8831), North American parent (FGSC 8578) and two representative progeny representing African clock phenotype (N309-89) and North American clock phenotype (N309-50). Results: We identified one candidate gene that meets our criteria; confirmed it's expression by qPCR and it's expression pattern is associated with parent genotype. Conclusions: Our approach using the expression profiles and SNP data of two parents and two representative progeny led us to identify a candidate gene for a complex clock adaptation phenotype.

One-color comparison of 7 conifer species in 2 tissue types: xylem and phelloderm. Between 4 and 28 biological repetitions per sample type, depending on the species, for a total of 142 slides.
