Control of ion absorption by phytochrome.

abstract：:Plants of Monstera deliciosa Liebm. pruned to exemplars with one leaf and one aerial root were labeled with 7.4 MBq (14)CO2 over the leaf blade. Microautoradiographs of soluble and insoluble radioactivity were prepared from three different regions of the aerial root. In addition, histochemical localization of ATPase w...
