Cereal aleurone responses to gibberellic acid (GA3) include activation of synthesis of hydrolytic enzymes and acidification of the external medium.
In addition, the activating effect of GA3 on the expression of carboxypeptidase III and thiol protease genes is more efficient when the hormone treatment is carried out at neutral pH.

Type III carboxypeptidase (CPD3) is one of the hydrolytic enzymes whose expression is up-regulated by gibberellins (GA) in the aleurones of germinated cereal grains.
A number of pyrimidine boxes and a sequence resembling the gibberellic acid response element (GARE) are observed in the region upstream of the transcription initiation site of the CPD3 gene, showing a characteristic of cereal GA-responsive genes.

Leucine aminopeptidase activity was high at the beginning, then it decreased; carboxypeptidase activity reached the highest value at day 5.
In order to examine the effects of plant growth regulators on detached cotyledons incubated with plant growth regulators [10 (-4) M benzyladenine (BA), gibberellic acid (GA3), indole acetic acid (IAA) and 10 (-5) M abscisic acid (ABA)], only benzyladenine was found promotive on protein mobilization.
