title: The fall and rise of apical dominance.
abstract: The plant hormone auxin, synthesised in the shoot apex, moves down the stem and inhibits lateral branching. Auxin does not travel upward into the branches, so it must act indirectly; for example, through a second messenger. However, recent work on auxin transport suggests a possible additional mechanism whereby auxin transport in the stem prevents the establishment of auxin transport out of the branches, inhibiting their growth.
