    Notes: [Auszug] Two recent reports have cast fresh doubt on the currently fashionable theory that auxin promotes and controls the extension growth of plant cells either by derepressing genes or by stimulating the synthesis of messenger UNA. The question of whether or not protein synthesis is involved seems to ...
