The Rieske iron‐sulfur cluster, which no‐one as yet has been able to identify in plant mitochondria, is identified in these mitochondria through the use of 5‐ N ‐undecyl‐6‐hydroxy‐4,7‐dioxobenzothiazole (UHDBT). The midpoint potential of the Rieske cluster in mung bean and potato mitochondria is + 300 mV. The orientation of the Rieske cluster in the potato mitochondrial membrane is identical to its orientation in animal mitochondrial and Rhodopseudomonas sphaeroides membranes but differs from that in chloroplast membranes.
