Mature Amaranthus hypochondriacus seeds contain non-processed 11S precursors

Using seed-produced protein fractions and a recombinant amaranth 11S-globulin, it was demonstrated that amaranth mature seeds contain non-processed 11S-globulins (proglobulins). The presence of these precursors is not a consequence of low vacuolar processing enzyme activity in developing amaranth seeds.
