Fig. 3.

docs mutants are affected in gravitropic responses. a At 28 days, docs1 mutant plants grown under hydroponic conditions in rhizoboxes (plexiglas plates filled with 5 mm diameter glass beads, see M&M for details) present a larger root cone angle than their respective controls. b, c Gravitropic response of docs1–1 mutant (black) is affected compared to Nipponbare control (gray) seedlings. Seedlings have been grown for 3 days in the dark on MS/2 solid medium before rotating the petri dishes of 90°. Radicle angles have been measured every hour for 10 h, and at 24 h (b, n = 13 for Koshihikari, n = 9 for docs1–1), and every 5 min for one hour (c, n = 8 for Koshihikari, n = 7 for docs1–1)
