The apoplastic α-amylase (EC 3.2.1.1) in pea (Pisum sativum L. cv. Laxton's Progress No. 9) seedlings was enhanced by a 4- to 6-fold with heat stress. Increased levels of the enzyme persisted for 48 h at least after the stress and subsequent heat treatments enhanced the activity further. These results indicate that the function of apoplastic α-amylase in vegetative tissues may be related to plant stress.
