Endogenous cyto kinins in the laminae and galls of erythrina latissima leaves



Endogenous cyto kinins in the laminae and galls of erythrina latissima leaves



Botanical Gazette 139(1): 36-41



The endogenous cytokinins which coeluted with Z [zeatin], ZR [zeatin riboside] and ZG [zeatin glucoside] increased in the leaf laminae and in the galls of E. latissima over the entire growing season. The highest concentrations were reached in autumn before the leaves senesced. In the galls 90% of the cytokinin activity was localized within the larvae, which made up only 1% of the tissue analyzed. While most of the activity in the leaf laminae was in the form of ZG, a storage or inactive form of the cytokinin, that in the larvae was in the form of the free bases, Z and ZR, regarded as the active form of the cytokinin. This, together with the fact that the cytokinins are very concentrated in the larvae, would ensure that the insect has the ability to mobilize is nutrient requirements even when the leaves may be exporting food reserves during autumn. The gall is apparently under the control of the parasite and this control is maintained as a result of the active accumulation of cytokinins from the leaf laminae and, if necessary, their conversion to the active forms by the larvae.
