| Abstract: | Partial purification of the ferredoxin form crude extracts and their spectrophotometric quantification by means the measuring at 312 nm permit the determination of the ferredoxin levels in leaves of citrus plants. The leaf contents of this protein are related with the total iron concentrations, as well as with the iron chlorosis symptoms of the plants. On the other hand, iron infiltration treatments on intact leaves enhanced the sythesis of the ferredoxin |
