Thermogenic Respiration in Aroids

Thermogenic Respiration in Aroids For reasons which will SOon become obvious, this review-at first glance polemic and too inclusive-pays more than the customary attention to biological matters. It deals with thermogenicity in plants, a property which, according to the available evidence, is connected with "cyanide-resistant respiration," a type of cellular respi­ ration insensitive to inhibition by terminal inhibitors such as cyanide", azide, and carbon monoxide (CO), and by inhibitors such as antimycin A and HOQNO, which act between band c-type cytochromes (18,62,63,73,80; cf 105,106). The definition is not absolute,since degrees of cyanide resistance varying from 0 to 100%,and even stimulation by cyanide (100), have been found in plant tissues, pollen grains, and mitochondria (18, 19, 23, 25,46, 70, 82, 86, 145, 146,201), often as a function of plant or organ development (131, 2(0).

Abstract

For reasons which will SOon become obvious, this review-at first glance polemic and too inclusive-pays more than the customary attention to biological matters. It deals with thermogenicity in plants, a property which, according to the available evidence, is connected with "cyanide-resistant respiration," a type of cellular respi­ ration insensitive to inhibition by terminal inhibitors such as cyanide", azide, and carbon monoxide (CO), and by inhibitors such as antimycin A and HOQNO, which act between band c-type cytochromes (18,62,63,73,80; cf 105,106). The definition is not absolute,since degrees of cyanide resistance varying from 0 to 100%,and even stimulation by cyanide (100), have been found in plant tissues, pollen grains, and mitochondria (18, 19, 23, 25,46, 70, 82, 86, 145, 146,201), often as a function of plant or organ development (131, 2(0). The insensitivity resides in the mitochondria (19,64,65, 150, 188,205,206).
