La fotosíntesis es la principal vía de entrada de energía en la biosfera y la ruta más importante de fijación y secuestro de dióxido de carbono. Aproximadamente la mitad de la productividad fotosintética ocurre en los océanos. Sin embargo, en estos ecosistemas nos encontramos grandes áreas pobres en fitoplancton debido a una...

In cyanobacteria and most green algae of the eukaryotic green lineage, the copper-protein plastocyanin (Pc) alternatively replaces the heme-protein cytochrome c6 (Cc6) as the soluble electron carrier from cytochrome f (Cf) to photosystem I (PSI). The functional and structural equivalence of 'green' Pc and Cc6 has been well established,...

We have investigated if the heterologous expression of a functional green alga plastocyanin in the diatom Phaeodactylum tricornutum can improve photosynthetic activity and cell growth. Previous in vitro assays showed that a single-mutant of the plastocyanin from the green algae Chlamydomonas reinhardtii is effective in reducing P. tricornutum...
