Se detecto fosforilacion ciclica con metosulfato de fanazina y fosforilacion no ciclica y reduccion con ferrocianuro en cloroplastos aislados provenientes de hojas de frijol enverdecientes, despues de 3 a 4 horas de iluminacion. La actividad comenzo cuando se inico la sintesis rapida de la clorofila. Las fotofosforilaxin de fotofosforilacion fueron comparables a niveles maduros equivalentes de 15 a 18 horas de desarrollo.
La fotorreduccion del ferrocianuro alcanzo un valor maximo hacia las 12 horas de iluminacion y posteriormente descendio a niveles normales hacia las 15 a 18 horas.
Fotofosforilación
Los datos indican que las fotosintesis I y II se presentan conjuntamente en el cloroplasto, pero no fueron completamente efectivas sino hasta una etapa mas avanzada de su desarrollo.
Los proplastidios y cloroplastos inmaduros mostraron altas capacidades para reducir el ferrocianuro en la oscuridad. Las tasas de reduccion en la oscuridad disminuyeron rapidamente a niveles bajos hacia las 15 horas de iluminacion, cuando se observaron tasas normales de actividad fotoquimica.
Despues de un periodo de inactividad de 2 a 3 dias, se noto un rapido incremento en el peso fresco de la hoja, en el momento en que el contenido total de clorofila alcanzo valores estables basados en peso fresco.
Tomando el peso fresco como indice de crecimiento, las hojas primordiales completaron su desarrollo al cabo de 6 a 7 dias de iluminacion. Cyclic phosphorylation with phenazine methosulfate and noncyclic phosphorylation and reduction with ferricyanide were detected in isolated chloroplasts from greening bean leaves after 3- 4 h of illumination.
Activity commenced when rapid synthesis of chlorophyll was initiated. Rates of photophosphorylation were comparable to mature levels by l h of development. Photoreduction of ferricyanide attained apeak value by 12 h of illumination and subsequently fell to normal levels by h.
The data suggested that photosystems I and II appeared concomitantly in the chloroplast but were not fully operative until later in development. Proplastids and immature chloroplasts exhibited high capacities to reduce ferricyanide in the dark. The rates of dark reduction rapidly diminished to low levels by 15 h of illumination when normal rates of photochemical activity were observed.
After a 2- to 3-day lag, a rapid increase in leaf fresh weight was noted at the time total chlorophyll content reached steady state values on a fresh weight basis.
