Relative 1000-seed weight in F
seeds from crosses of lpcat1 and AS11 mutants. Line numbers are designated as listed in Additional file 2: Table S3, with genotypes designated on the × axis. dgat1/lpcat1 null for both mutations # 3-3-9; lpcat1 homozygous mutant N123480-6; AS11 dgat1 homozygous mutant CS3861; dgat1/lpcat1 homozygous for both mutations #3-3-12. The values are reported relative to the double null controls set at 100% and are the average of triplicate determinations ± S.D.
