Abstract
Sinapine (sinapoyl-choline) is accumulated in the cotyledones of Sinapis alba during the main growth phase of the developing embryos. It is degraded during germination of older embryos which have not reached full maturation and of mature seeds, but remains stable in young embryos. The main product of degradation is sinapoyl-glucose. [14C]phenylalanine is not only incorporated into sinapine during the accumulation phase in situ but just so into isolated embryos which do not accumulate the substance further. Synthesis takes place in the cotyledones. Their synthesizing capacity (incorporation of [14C]phenylalanine) is correlated with the growth rate of the cotyledones.Keywords
