 Title    Further Studies on Induction of Enzymes of Phytoalexin Synthesis in Soybean and Cultured Soybean Cells  
 Abstract    The glucan elicitor from cell walls o f the fungal pathogen, Phytophthora m egasperm a f. sp. glycinea, caused a decrease in activity o f 3-hydroxy-3-m ethylglutaryl coenzym e A reductase in wounded soybean cotyledons, whereas wounding alone led to an increase in the activity o f this enzyme. A decrease o f HM G -CoA reductase activity after elicitor treatment was also found in soybean hypocotyls and soybean cell cultures. In contrast to the activity o f H M G -CoA reductase, the activity o f dim ethylallylpyrophosphate: 3,6a,9-trihydroxypterocarpan dimethylallyltransferase increases after elicitor challenge o f soy­ bean cell cultures and after inoculation o f soybean hypocotyls (cv A m so y 7 1) with m ycelium o f either race 1 (incom patible) or race 3 (com patible) o f P. megasperma.

 Title    On the Structure of Lignin from Soybean Cell Suspension Cultures  
 Abstract    Treatment of soybean cell cultures according to the Björkman-procedure yields a "milled wood lignin" (MWL), which has been shown to be a hardwood lignin by thermofractography and carbon-13-NMR spectroscopy. The 13C-NMR spectrum of this acetylated lignin indicates that this lignin contains relatively high amounts of cinnamyl alcohol and p-hydroxyphenyl groups compared with other typical hardwood lignins. The lsC-spectrum of the acetylated MWL also indicates the presence of carbohydrate components, which are apparently very tightly bound to the lignin.
