Growth Protocol:	Seeds from wildtype Arabidopsis thaliana ecotype Columbia (Col-0), shortroot-2 (Col-0 background), and scarecrow-4 (Landsberg background backcrossed to Col-0 at least 5 times) were surface sterilized with a 50% (v/v) bleach, 0.05% (v/v) Tween-20 solution for 10 minutes and subsequently stratified for 48 hours at 4°C. Seeds were sown at a density of ~150-300 seeds/row on 1X Linsmaier and Skoog (LSP03-1LT, Caisson Labs; pH 5.7), 1% sucrose media covered by 100/ 47 µm mesh. Plates were placed vertically in a Percival chamber programmed to 16h light, 8h dark conditions at 22°C.
