The Glyoxylate Cycle in Maize Scutellum

Dry matter changes and carbohydrate metabolism of germinating soybeans

“…He suggested that the metabolism of the corn embryo during the early period of germination is based on seed fats and soluble carbohydrates. Oaks and Beevers (1964) supported Dure's finding that there was a progressive loss of lipid material from cereal scutella during germination and that the stored lipid is of relevance to the carbohydrate economy of the seedling.…”

“…The reactions of this pathway and the enzymes necessary for the reactions to occur have been demonstrated in a number of oily seeds (Beevers, 1961;Bradbeer and Stumpf, 1959;Carpenter and Beevers, 1959;Romberg and Beevers, 1957;and Yamamoto and Beevers, 1960), and also in the maize scutellum (Oaks and Beevers, 1964),…”

Activation and Oxidation of Acetic Acid-1-C14 by Cell Free Homogenates of Germinating Peanut Cotyledons

“…These workers therefore suggested that the enzymes isocitric dehydrogenase and a-ketoglutaric dehydrogenase, although present, may contribute relatively little to the dissimilation of isocitrate in castor bean (3). Oaks and Beevers (11) stress that, contrary to the condition in fatty see Is (castor bean en-losperm) both the tricarboxylic acid and the glyoxylic acid cycles contribute to acetate utilization in cereals (corn scutella), as they do in many microorganisms.…”

“…Fractionation of this system indicated that the long chain fatty acid activating enzyme is particulate, while the conversion of the activated fatty acids to acetyl-CoA is catalyzed by soluble enzymes (13 acetyl-thiokinase in plant tissues (10), and has warranted the use of labeled acetate as substrate in investigations dealing withl the conversion of storage lipids to sugar during seedl germination (1,11 …”

Physiological and ultrastructural investigations of caryopsis dormancy in Setaria lutescens (Gramineae)

“…Although the develop mental pattern of glyoxysomes in the Gramineae appears similar to that in oleaginous species (Longo and Longo, 1970a;Longo, Bernasconi, and Longo, 1975;Longo and Longo, 1970b), the total lipid loss is typically not as great (Dure, 1960;MacLeod and White, 1961;Ingle, Beevers, and Hageman, 1964;and Tavener and Laidman, 1972a) as in oleaginous seeds (Ching, 1970;Muto and Beevers, 1974). In addition, other evidence suggests that, during germination, the Krebs cycle plays a greater role in the assimilation of the end-products of 6-oxidation in the Gramineae than occurs in oleaginous seeds (Oaks and Beevers, 1964;Effer and Ranson, 1967).…”
