Structural and immunological homologies between storage proteins in the wood and the bark of poplar

Summary Overwintering bark of poplar ( Populus x euramericana cv. ›Robusta‹) contains three major storage polypeptides with 32, 36 and 38 kDa. They exhibit very similar physicochemical and immunological properties, and could be related to a storage polypeptide with 32 kDa isolated from the wood of dormant poplars. The present study describes the structural and immunological homologies between vegetative storage proteins in bark and wood of poplar.
