  bibo_abstract:
  - Asymmetric auxin distribution is instrumental for the differential growth that
    causes organ bending on tropic stimuli and curvatures during plant development.
    Local differences in auxin concentrations are achieved mainly by polarized cellular
    distribution of PIN auxin transporters, but whether other mechanisms involving
    auxin homeostasis are also relevant for the formation of auxin gradients is not
    clear. Here we show that auxin methylation is required for asymmetric auxin distribution
    across the hypocotyl, particularly during its response to gravity. We found that
    loss-of-function mutants in Arabidopsis IAA CARBOXYL METHYLTRANSFERASE1 (IAMT1)
    prematurely unfold the apical hook, and that their hypocotyls are impaired in
    gravitropic reorientation. This defect is linked to an auxin-dependent increase
    in PIN gene expression, leading to an increased polar auxin transport and lack
    of asymmetric distribution of PIN3 in the iamt1 mutant. Gravitropic reorientation
    in the iamt1 mutant could be restored with either endodermis-specific expression
    of IAMT1 or partial inhibition of polar auxin transport, which also results in
    normal PIN gene expression levels. We propose that IAA methylation is necessary
    in gravity-sensing cells to restrict polar auxin transport within the range of
    auxin levels that allow for differential responses.@eng
