title: [Evolution of phytohemagglutinins from different parts of the seed in pea seedlings].
abstract: Two different PHA were detected in every part of massive pea seed: embryo, cotyledons and seed coat. These proteins disappeared from the leaves, stems and roots during early stage of seedling development while they lasted longer in the cotyledons. On the other hand two PHA do not disappear at the same rate which could be related to a differential susceptibility toward activity of proteolytic enzymes during germination and seedling development.
