Recently it was discovered that auxin promotes gibberellin (GA) biosynthesis in decapitated stems of pea (Pisum sativum L.) and tobacco (Nicotiana tabacum L.), and here we review the evidence for this interaction. We also discuss the possible relationship between auxin and the mechanisms by which bioactive GAs (such as GA1) regulate their own levels, and the implications of the auxin-GA interaction for the control of plant growth. It is now possible to envisage auxin as a messenger linking the apical bud with the biosynthesis of active GAs in the expanding internodes. Finally, new evidence is presented that the promotion of growth by GA1 does not depend on GA1-induced increases in auxin content.
