摘要：

Pulse‐chase labelling experiments demonstrate that photoassimilated 14C‐bicarbonate is translocated from the host red alga Odonthalia floccosa (Esper) Falkenberg to the parasite Harveyella mirabilis (Reinsch) Schmitz & Reinke. The primary path of translocation is from host cortical cells (the site of photoassimilation) to the erumpent parasite pustule via the zone of interdigitation. The latter is a tissue region in which rhizoidal cells of Harveyella grow between, and establish secondary pit plugs with medullary cells of Odonthalia. A secondary translocation pathway occurs from isolated host cells dispersed in the pustule of Harveyella to adjacent parasite cells. Copyright © 1979, Wiley Blackwell. All rights reserved
