| Description
| - Nedostatek železa způsobuje rychlý pokles množství enzymů nitrogenázy a jejich aktivity. Nemění se množství enzymů Fotosystému I a fykobilisomů. Mění se i charakteristický denní rytmus aktivity Fotosystému II a nitrogenázy. Trichodesmium při nedostatku železa omezuje aktivitu fixace dusíku, ale fotosyntetická aktivita zůstává zachována. (cs)
- As iron (Fe) deficiency is a main limiting factor of ocean productivity, its effects were investigated on interactions between photosynthesis and nitrogen fixation in the marine nonheterocystous diazotrophic cyanobacterium Trichodesmium IMS101.Biophysical methods such as fluorescence kinetic microscopy, fast repetition rate (FRR) fluorimetry, and in vivo and in vitro spectroscopy of pigment composition were used, and nitrogenase activity and the abundance of key proteins were measured.Fe limitation caused a fast down-regulation of nitrogenase activity and protein levels. By contrast, the abundance of Fe-requiring photosystem I (PSI) components remained constant. Total levels of phycobiliproteins remained unchanged according to single-cell in vivo spectra. However, the regular 16-kDa phycoerythrin band decreased and finally disappeared 16-20 d after initiation of Fe limitation, concomitant with the accumulation of a 20-kDa protein cross-reacting with the phycoerythrin antibody. Concurrently, nitrogenas
