Abstract The complex social behavior of M. xanthus makes it an excellent model system to study the relationship between genotype and phenotype. Under nutrient rich conditions, a swarm of M. xanthus cells coordinate their movement outward in search of prey. When starved, cells condense into multicellular structures called aggregates. Taken together, these two aspects of the M. xanthus life cycle display several sub-traits that are used to describe its phenotype. Furthermore, the genome of M. xanthus is large, encoding a predicted 7,314 genes, many of which have been linked to aspects of its multicellular phenotype. This work presented here addresses the genotype-to-phenotype (G2P) problem as it relates to the annotation of a biological process in a model system. The first project addresses G2P from a population genetics approach; we constructed a mutant strain library consisting of 180 single gene knockouts of the ABC transporter superfamily of genes to examine the distribution of mutant phenotypes among an entire group of genes.

Carroll, and Nikolay Bliznuyk Abstract We propose statistical methods for comparing phenomics data generated by the Biolog Phenotype Microarray (PM) platform for high-throughput phenotyping. Instead of the routinely used visual inspection of data with no sound inferential basis, we develop two approaches. The first approach is based on quantifying the distance between mean or median curves from two treatments and then applying a permutation test; we also consider a permutation test applied to areas under mean curves. The second approach employs functional principal component analysis. Properties of the proposed methods are investigated on both simulated data and data sets from the PM platform. KEYWORDS: functional data analysis, principal components, permutation tests, phenotype microarrays, high-throughput phenotyping, phenomics, Biolog Author Notes: Zorych and Bliznyuk were supported by the Texas A&M Postdoctoral Training Program of the National Cancer Institute (CA90301).

These systems use to present low levels of basal 4 expression. However, they can be induced by environmental signals or stresses which can 5 lead to situations of phenotypic induced resistance. In contrast to efflux pumps substrates, 6 inducers of these systems have not been thoroughly studied. In this work, we have applied a 7 novel high-throughput methodology in order to identify inducer molecules of the 8 Stenotrophomonas maltophilia SmeVWX and SmeYZ efflux pumps.

The title of this year’s event “Florence Conference on Phenotype MicroArray Analysis of Cells” reflects our aspiration to provide an opportunity for researchers working in different fields of biology to share, compare and evaluate multiple types of Phenotype MicroArray data, and to show the numerous applications of this high-throughput phenomic technology and its potential in the cell phenotyping area. For the first time, the Florence Conference programme includes a significant number of talks on the application of Biolog Phenotype MicroArray to eukaryotic cell analysis, including mammalian cells and multi-organism interactions. We believe that this third edition of the Florence Conference will provide a forum for discussing the state of the art of Phenotype MicroArray technology in relation to other omics data as well as presenting new ideas for future research.

  • Phenomic and Genomic Diversity of a Bacterial Species in a Local Population
    Phenomic and genomic diversity of a bacterial species in a local population Ganesh Raoji Lad Doctor of Philosophy University of York Department of Biology September 2013 Abstract Biology aims to understand life and life processes. DNA is the blueprint of life and hence analysis of DNA sequences is expected to explain the way in which life manifests. The genomes of a large number of organisms have been sequenced and more are being sequenced every day. However, just knowing the DNA sequence does not tell us the manner in which it expresses itself to confer phenotypes on an organism. Hence, after the DNA sequence is obtained, it is important to identify the genes in the sequence, their organisation, their complex interactions and their function in the expression of different phenotypes. Bacteria belonging to the genus Rhizobium exhibit immense genotypic and phenotypic diversity. In this thesis, we look at the difference in the metabolic fingerprints of 72 isolates belonging to the genus Rhizobium isolated from leguminous plants near Wentworth College, University of York. Sequence data from the 72 isolates was used to correlate the phenotypic diversity to the sequence diversity in order to predict the role of genes involved in metabolism of the substrates investigated. Of the 95 substrates investigated, the ability of the strains to utilize only one substrate viz. -hydroxybutyrate (GHB) showed a near absolute correlation to the presence of two genes in the genome data viz. pRL100135 and pRL100136. The mutation of pRL100135 showed a pronounced decrease in the ability of the test organism to use GHB. The mutation of pRL100136 decreased, but did not abolish, the ability to use GHB.

Phenotype MicroArray (PM) is a high-throughput technology that 3 provides a set of nearly 2000 culture conditions (about 200 carbon sources, 400 nitrogen sources, 4 100 phosphorous and sulphur sources, 100 nutrient supplements, and a range of pH, ion and 5 osmotic gradients) in which one can test the metabolic activity of a microorganism. PM uses 96- 6 wells plates and each well of the plates is designed to test a different phenotype. The plates are 7 inoculated with a standardized cell suspension and incubated, typically for 24-48 hours.
