|a The metabolism of 14C-acetate was investigated during the in vitro germination of yellow lupine seeds. Carbon atoms (14C) from the C-2 position of acetate were incorporated mainly into amino acids: aspartate, glutamate, and glutamine and into sugars: glucose, sucrose, and fructose. In contrast to this, 14C from the C-1 position of acetate was released mainly as 14CO2. Incorporation of 1-14C and 2-14C from acetate into amino acids and sugars in seedling axes was more intense when sucrose was added to the medium. However, in cotyledons where lipids are converted to carbohydrates, this process was inhibited by exogenous sucrose. Since acetate is the product of fatty acid beta-oxidation, our results indicate that, at least in lupine, seed storage lipids can be converted not only to sucrose, but mainly to amino acids. Inhibitory effects of sucrose on the incorporation of 14C from acetate into amino acids and sugars in cotyledons of lupine seedlings may be explained as the effect of regulation of the glyoxylate cycle by sugars
