Project

Mutant libraries are made using transposon insertion mutagenesis. Many of these have been characterized but in breeding it is neccicary to determine if the mutation is wildtype, heterozygous or homozygous. This is often done with qPCR but the process is time-consuming and expensive. We are working with Chip Hunter to develop the statistical methods and software to pull down the mutation sites and sequence them in parallel. The project has required us to apply new statistical methods for the analysis of compositional count data to accurately predict genotype.
