Project Number: 6208-21000-020-19
Start Date: Apr 01, 2012
End Date: Sep 30, 2013
1. Perform high-density Illumina genotyping of PI610727, Shan Qui Red, PI567946, Tx430, and SRN39 (parents of RIL populations) and bioinformatics for single nucleotide polymorphism analysis. 2. Pursue re-analysis of cold-tolerance QTL data from these 4 RIL populations in a single, joint genome-wide association analysis using the high-density genotypes from part (1). 3. Perform pilot expression study: collect RNA from the cold-grown inbred parents (same 5 lines as in part 1) and their hybrids during germination, perform RNAseq, and look for cis-regulatory differences (differences in abundance between parental alleles) in the hybrids. 4. Perform statistical analysis and documentation (in form of graphs, photos, etc.) of results and provide the ARS coordinator with data, documentation, and reports from the endeavors of the agreement for use in submission of reports to funding agency.
