The metabolism of oleoyl coenzyme A (CoA) was examined in developing seed from two soybean (Glycine max [L.] Merr.) genotypes: Williams, a standard cultivar and A5, a mutant containing nearly twice the oleic acid (18:1) content of Williams. The in vitro rates of esterification of oleoyl-CoA to
The activity of 1,3-beta-d-glucan synthase assayed in the presence of digitonin in a microsomal preparation from suspension-cultured cells of Glycine max can be fully inhibited by unsaturated fatty acids, trienoic acids being most effective. Lysophosphatidylcholine, platelet-activating factor,
The enzymes 1,2-diacylglycerol cholinephosphotrans-ferase (CPT) and lysophosphatidylcholine acyltransferase (LPCAT) are important in lipid metabolism in soybean seeds. Thus, understand-ing the genes that encode these enzymes may enable their modification and aid the improvement of soybean oil
Addition of the active auxins indole-3-acetic acid, 2,4-dichlorophenoxyacetic acid or alpha-naphthylacetic acid to cultured soybean (Glycine max L.) cells prelabeled with ethanolamine or choline increased the radioactivity in the lysophosphatidylethanolamine (LPE) or lysophosphatidylcholine (LPC)
Addition of the animal ether phospholipid platelet-activating factor, 1-0-alkyl-2-acetyl-sn-glycero-3-phosphocholine, (PAF) stimulates medium acidification in cultured soybean (Glycine max L.) cells. The pH of the medium after 8-10 hours is on the average one pH unit lower than in controls. With
Cultured cells of Glycine max (L.) Merr. v. Corsoy were permeabilized by treatment with L-α-lysophosphatidylcholine (LPC). The permeabilized cells were capable of uptake and incorporation of deoxynucleoside triphosphates into DNA. Incorporation of exogenous nucleotides into DNA was linear for at
