• Membrane proteins labeled in vivo from cold-acclimated and ABA-treated alfalfa seedlings of two cultivars differing in cold-tolerance have been compared by SDS polyacrylamide gel electrophoresis and fluorography. Results thus obtained indicate that several qualitative changes occur in the membrane protein-profile specifically in response to cold acclimation or ABA treatment. While some polypeptides disappear from the non-acclimated protein patterns, others specifically appear in response to acclimation. Separation by two-dimensional gel electrophoresis and fluorography has confirmed the above and has enabled us to detect two proteins of Mr 42 kDa and 120 kDa that are induced by both acclimation and ABA treatment in the freezing tolerant cultivar.
