Fig 1. YUC-dependent auxin production is required for ethylene-inhibited root growth.

Fig 1

(A) Primary root phenotypes of Nipponbare (Nip), overexpressing OsEIN2 (EIN2-OX) and overexpressing OsEIL1 (EIL1-OX) transgenic lines treated with or without 10 ppm ethylene, in the absence or presence of 10 μM yucasin. Rice seedlings were grown in the dark for 3 d. Bar = 10 mm. (B) Root length of the plants shown in (A). Values are shown as the mean ± SD of 20–30 seedlings. The experiment was repeated at least three times with similar results. ** indicates significant difference compared to air at P < 0.01. (C) Expression of YUC genes in 3-d-old etiolated seedling roots. 3-d-old etiolated seedlings were treated with or without 10 ppm ethylene for 3 h. The RNAs from roots were isolated for qPCR. The experiment was repeated at least five times with similar results. Bars indicate ± SD.
