Iron Uptake and Translocation by Macrocystis pyrifera.
Parameters of iron uptake have been determined for blade tissue of Macrocystis pyrifera (L.) C. Ag. These include the effects of iron concentration, light, various inhibitors, and blade type. All experiments were conducted in the defined artificial seawater Aquil. Iron uptake is light independent, energy dependent, and dependent on the reduction from Fe(3+) to Fe(2+). Iron is concentrated in th...
متن کاملTranslocation of 14 C in Macrocystis pyrifera ( Giant Kelp ) 1
The pattern of import and export of IC-labeled assinuates in Macrocystis pyrifers (L) C. A. Agardh in southern California was studied by labeling single blades on frods, in situ, with I'4CINaHCO3 for 24 bours. The pattem was found to be similar to that known in dicotyedons: actively growing tissue imported and did not export. As a blade reached maturity it began to export, at first only acropet...
متن کاملPhotoprotection in the brown alga Macrocystis pyrifera: evolutionary implications.
The dissipation of energy as heat is essential for photosynthetic organisms to protect themselves against excess light. We compared Photosystem II florescence changes (non-photochemical quenching, NPQ) in the brown alga Macrocystis pyrifera with that of Ficus sp., a higher plant to examine if the mechanism of heat dissipation (energy-dependent quenching, qE) differs between these evolutionary d...
متن کاملThe Ecology of Microbial Communities Associated with Macrocystis pyrifera
Kelp forests are characterized by high biodiversity and productivity, and the cycling of kelp-produced carbon is a vital process in this ecosystem. Although bacteria are assumed to play a major role in kelp forest carbon cycling, knowledge of the composition and diversity of these bacterial communities is lacking. Bacterial communities on the surface of Macrocystis pyrifera and adjacent seawate...
متن کاملBrain Anatomy and Histology of Orange Spotted Grouper (Epinephelus coioides)
This research was carried out to identify the different layers and cells of orange spotted grouper brain for further toxicological experiments and defects brought by xenobiotics during exposure periods.The anatomy and histology of the brain of orange spotted grouper was illustrated and compared to mammals and other fishes. The preserved structures of teleosts brain species were different as com...
