摘要
The polypeptides in the leaf blades, petioles and apices from photoinduced and noninduced Xanthium strumarium L. were compared by two dimensional gel‐electrophoresis. A 15 kDa and a 16 kDa polypeptide were detected in gels of the leaf blade from noninduced, but not from induced, plants. Similarly, an acidic 9 kDa polypeptide was detected in the apices from noninduced plants, but not in apices from induced plants. Both the apices and petioles from noninduced plants showed a 34 kDa polypeptide which was absent in tissues from induced plants. Thus, the disappearence of identifiable polypeptides from photoinduced tissues may be associated with the photoinductive short‐day treatment that leads to flowering.
