| Abstract: | Shoot apical meristcms of vegetative and induced plants of Sinapis alba L. were labelled with [35S] methioninc for 2 h and the proteins were then separated by isoelectric focussing and polyacrylamide gel electrophoresis. Quantitative and possibly qualitative changes in the complement of proteins being synthesised during evocation were detected in the meristem, distal to the primordia, 50 to 52 h after the beginning of the inductive long day. This was before morphological changes in the meristem, and before the initiation of flower bud primordia. |
