Abstract:
Temperature responsive plant growth, such as thermo-morphogenesis, varied greatly among Arabidopsis natural accessions. Here we describe a procedure to identify causal genes for thermo-morphogenesis variation by a genome-wide association study (GWAS). It includes methods of measuring thermo-responsive rosette growth architecture, using GWA-Portal webtool for GWAS, analyzing haplotypes, and validating functional natural variations. In addition, we discuss key factors that affect the success of identifying causal genes from GWAS.
