Abstract
Extracts of uninduced thalli, induced thalli, stalks, antheridiophore and archegoniophore disks of Marchantia polymorpha were subjected to starch‐gel zone electrophoresis. Developed gels were treated with appropriate reaction mixtures to detect sites of activity for 12 enzyme systems; only phosphatases, esterases, and peroxidases were observed. Although common sites of phosphatase, peroxidase, and esterase activity were detected in all tested extracts, additional sites of peroxidase and esterase activity were found in extracts from antheridiophore disks. The antheridia provided the additional esterases as determined by the electrophoresis of antheridial extracts and by a histochemical test for esterases in sections of antheridiophores.
