Use of Maize (zea Maysl.) Mutator Transposon-Induced Mutants of Thebonnmuresource for Forward and Reverse Genetics Studies
Cold Spring Harbor Protocols(2024)
摘要
TheBonnMuresource represents a tagged collection of maize (Zea maysL.)Mutator(Mu) transposon-induced mutants, designed for functional genomics studies. Here, we describe the use of theBonnMucollection for identifying and characterizing mutations. Specifically, we describe workflows for use in both reverse and forward genetics strategies in maize. For reverse genetics, users first acquire aBonnMuF2stock of interest based on data accessible at the Maize Genetics and Genomics Database (MaizeGDB). We provide details here for their subsequent propagation and for the confirmation ofMuinsertions by genotyping via PCR, with the ultimate goal of establishing genotype–phenotype relationships of interest. For forward genetics studies, we describe a workflow that involves a combined approach of Mutant-Seq (Mu-Seq) and bulked segregant RNA-seq (BSR-Seq), to identify the causal gene underlying a mutant phenotype of interest.
