FIGURE 1.

Variations of seed composition within the context of the protein content genotype are shown. The pie charts show the relative distribution of proteins comprising the seed proteome of the standard soybean line Jack, a line that silences β-conglycinin α,α′, another line that silences both β-conglycinin and glycinin, and a line where GFP-HDEL forming ER-derived protein bodies mimic of glycinin in the background of β-conglycinin silencing. Each of these seeds contains about the same total protein content while the proteome of each of these seeds varies. This demonstrates how the genomic framework controls the protein content genotype that can be rebalanced by protein composition plasticity.
