WebCytochrome b 561 (cyt b 561) is a trans-membrane cytochrome probably ubiquitous in plant cells. In vitro, it is readily reduced by ascorbate or by juglonol, which in plasma membrane (PM) preparations from plant tissues is efficiently produced by a PM-associated NAD (P)H∶quinone reductase activity.
