The amylases of the second leaves of barley seedlings (Hordeum vulgare L. cv Betzes) were resolved into eight isozymes by isoelectric focusing, seven of which were beta-amylase and the other, alpha-amylase. The alpha-amylase had the same isoelectric point as one of the gibberellin-induced alpha-amylase isozymes in the aleurone layer. This and other enzyme characteristics indicated that the leaf isozyme corresponded to the type A aleurone alpha-amylase (low pI group). Crossing experiments… CONTINUE READING
