From: Historical trend on seed amino acid concentration does not follow protein changes in soybeans

Relative genetic gain of protein and amino acid concentrations (a) and the relative-to-protein genetic gain of amino acid concentrations (b), calculated from 13 soybean genotypes released from 1980 to 2014 period. Points represent the medians of bootstrapped distribution with their respective 95% confidence intervals (small horizontal lines). Black solid points represent the AAs with significant relative gains, whereas the empty points are non-significant (95% CI including zero).
