| Standard Gene Set Name | SWARUP_AUXIN_ROOT_UP |
| Species | Arabidopsis thaliana |
| Brief Description | Induced by auxin during lateral root initiation in tissues surrounding the initiation site (Table S1 PubmedID:18622388) |
| Full Description/Abstract | Lateral roots originate deep within the parental root from a small number of founder cells at the periphery of vascular tissues and must emerge through intervening layers of tissues. We describe how the hormone auxin, which originates from the developing lateral root, acts as a local inductive signal which re-programmes adjacent cells. Auxin induces the expression of a previously uncharacterized auxin influx carrier LAX3 in cortical and epidermal cells directly overlaying new primordia. Increased LAX3 activity reinforces the auxin-dependent induction of a selection of cell-wall-remodelling enzymes, which are likely to promote cell separation in advance of developing lateral root primordia |
