Outline of Final Research Achievements

To identify the paternal factors that promote seed development, we performed genome-wide association study (GWAS) of intraspecific seed size of Arabidopsis thaliana. We performed GWAS for size of seeds sired by crossing between Col-0 accession as pistil parents and 123 accessions as pollen donors. We also performed GWAS for seed size of tetraploid Col-0 as pistil parents and 65 accessions as pollen donors. In total, eight association signals for seed size were identified, five signals for crosses between diploid parents and three signals for interploidy crossing.
