Metabolism of micronutrient elements in higher plants. II. Effect of copper deficiency on the isocitric enzyme in tomato leaves.
The r81e of copper as a component of such enzymes as ascorbic acid oxidase and polyphenol oxidase has been well established (1, 2). When plant tissues were made copper-deficient, the activities of these particular oxidases were significantly diminished, while other enzymes were unchanged or increased in concentration, resulting in an over-all change in enzyme pattern characteristic of the metal...
متن کاملNickel: a micronutrient essential for higher plants.
Nickel was established as an essential micronutrient for the growth of temperate cereal crops. Grain from barley (Hordeum vulgare L. cv ;Onda'; containing 40 to 80 nanograms of Ni per gram dry weight) grown in solution culture with negligible Ni concentrations (< 30 nanograms of Ni per liter) exhibited greatly reduced germination rates (i.e. 50% less than grain from Ni-adequate plants) and seed...
متن کاملFat Metabolism in Higher Plants
The discovery and isolation of the multienzyme system responsible for p oxidation of fatty acids to acetyl CoA’ have stimulated investigation of the synthesis of long chain fatty acids by multiple @ condensation of the acetyl CoA. In 1953 Van Baalen and Gurin (1) were the first to demonstrate that acetate was incorporated into fatty acids by aqueous extracts of pigeon liver. In 1953 Stansly and...
متن کاملMetabolism of hydrogen cyanide by higher plants.
A survey has been made of the occurrence and distribution of three enzymes which metabolize cyanide in a variety of higher plants including both cyanogenic and non-cyanogenic species. The enzymes investigated were beta-cyanoalanine synthase, rhodanese and formamide hydrolyase. beta-Cyanoalanine synthase was found to be present in every higher plant tested whereas rhodanese was found to occur fa...
متن کاملThe metabolism of hexose and pentose phosphates in higher plants.
The pathway of carbohydrate degradation, which begins with the action of G-6-P dehydrogenase’ on G-6-P, has been studied by a number of workers (l-9). Their results have shown the operation of this scheme in a variety of tissues (yeast, red blood cells, and mammalian liver). The existence of G-6-P dehydrogenase in various seeds (10) suggests the occurrence of this system in higher plants. The p...
