Characterization Of Genes And Pathways Controlling Biofilm Formation In Saccharomyces Cerevisiae, Neha Sarode

Doctoral Dissertations

Biofilms are a mode of growth where aggregated cells adhere to a foreign surface and grow as a complex community. Biofilms have found wide utility in commercial industries, however infections caused by biofilms in clinical settings are a major cause of concern. Understanding molecular details of biofilm formation could help in exploitation or elimination efforts.

We utilize Saccharomyces cerevisiae as a model system to study biofilm formation. S. cerevisiae strain belonging to genetic background Σ [sigma] 1278b is capable of forming biofilms, on low density (0.3%) agar media. When grown at 25°[degree] C for 5 days, it develops into an …

An Integrative Functional Genomics Approach Towards Quantitative Trait Gene Nomination In Existing And Emerging Mouse Genetic Reference Populations, Vivek Philip

Doctoral Dissertations

An approach that has been widely applied for the genetic dissection of complex traits is Quantitative Trait Locus (QTL) mapping. QTL mapping identifies genomic regions that harbor polymorphisms, responsible for the observed variation in a complex trait. If these polymorphisms are located within a gene, then these genes are called Quantitative Trait Genes (QTG). Prior to advancements in QTL mapping populations, QTL mapping resolution was often poor, resulting in large QTL intervals. Therefore, after mapping a QTL, fine mapping was initiated to further reduce the QTL interval and to identify the QTG. While successful, fine mapping using genetic approaches have …
