IAA-peroxidase relation in the microsporocytes and anther wall during successive stages of meiosis in Larix europaea L.
During anther meiosis in Larix europaea considerable variations in the level of peroxidase activity and endogenous auxin content occur both in the microsporocytes and in the anther wall. However, the IAA-peroxidase relations are different in each of these two parts of the anther. In the anther wall...

| description | During anther meiosis in Larix europaea considerable variations in the level of peroxidase activity and endogenous auxin content occur both in the microsporocytes and in the anther wall. However, the IAA-peroxidase relations are different in each of these two parts of the anther. In the anther wall characterized by the occurrence of anodic isoperoxidases, the changes in peroxidae activity show a positive correlation with those in endogenous auxin content. In the microsporocytes containing almost only cathodic asoperoxidases the levels of endogenous auxin content and peroxidase activity show a reverse correlation. Thus a preponderance of isoperoxidases showing IAA-oxidase properties occur only in the microsporocytes. These results suggest the important role of the IAA=peroxidase system in the mechanism of differentiation of cells undergoing anther meiosis. |
