Differential action of dithiothreitol and magnesium chloride on isolated wheat leaf chloroplast aging in light and dark

Differential action of dithiothreitol and magnesium chloride on isolated wheat leaf chloroplast aging in light and dark

Plant Physiology and Biochemistry New Delhi 16(2): 135-140

Chloroplast aging showed 2 distinct degradative processes; a slow loss of photosynthetic pigments and a faster loss of DCPIP-Hill reaction activity. These 2 processes were differentially regulated by dithiothreitol (DTT) and/or MgC12. The loss of electron transport activity of isolated chloroplasts was deferred by DTT and MgC12 individually. Their actions were additive for electron transport efficiency of chloroplasts. However, their action on pigment degradation was antagonistic.
