Analysis of GS polypeptides in poplar trees. Proteins were extracted from different organs of 2-month-old hybrid poplar. L, leaf. S, Stem. R, root. Thirty micrograms of proteins per lane were separated by PAGE and then transferred to a nitrocellulose membrane, where the proteins were probed using a specific antibody developed against pine GS [19]. A, One dimensional analysis. B, Two dimensional analysis. Spot variants in two dimensional gel separation of GS polypeptides has been previously reported [31] which could be the result of post-translational modifications. The molecular size (kDa) of protein markers are indicated on the left. Major GS spots observed in the different experiments are marked by arrows.
