Leucine-(U)-C(14) applied to the midrib of a young phylloid of Delesseria sanguinea moves basipetally and acropetally and eventually appears in other phylloids of the same plant. The highest velocity of transport calculated was 63 cm/h. The pathway of movement seems to be the veins of the phylloids and the central core of the cauloid.

Phytoferritin in the red alga Constantinea (Cryptonemiales)
Journal of Ultrastructure Research, 1980Chloroplasts in reproductive blades of the marine red alga Constaninea subulifera contained crystalline aggregations of phytoferritin. The native electron density of the particles' iron component was demonstrated in unstained sections, sections deosmified with periodic acid, and specimens prepared without osmium postfixation.

Membrane tubules in the tetraspores of a red alga
Protoplasma, 1984Newly released tetraspores of the red algaNitrophyllum punctatum exhibit numerous tubular structures in their peripheral cytoplasm. They are formed by a unit membrane and present an evident continuity with the plasmalemma. Sometimes they are branched. They seem to increase the total cell surface and might be involved in secretion or osmoregulation.

The origin of red algae and the evolution of chloroplasts
Nature, 2000Chloroplast structure and genome analyses support the hypothesis that three groups of organisms originated from the primary photosynthetic endosymbiosis between a cyanobacterium and a eukaryotic host: green plants (green algae + land plants), red algae and glaucophytes (for example, Cyanophora). Although phylogenies based on several mitochondrial genes
