Abstract
(SO42-)-S-35 and glucosinolate precursors were administered to investi gate the capacity of oilseed rape intact whole pods, isolated pod wall s and seeds to carry out reactions of the glucosinolate biosynthetic p athway, Pod walls incorporated S-35-label from (SO42-)-S-35 into both the thio-glucose and sulphonate-sulphur of glucosinolates, Pulse-label ling experiments showed that pod walls were the predominant source of the glucosinolates accumulated by the seeds. Isolated immature seeds w ere capable of reductive assimilation of (SO42-)-S-35 and incorporated S-35 into sulphur-containing amino acids and the sulphonate moiety of glucosinolates, but were not able to incorporate S-35 into the thio-g lucose of glucosinolates.
