Root morphology and ROS level in YtA and YtB. A 3-day-old root of YtA and YtB on 1/2 MS vertical plates. B Confocal micrographs illustrating ROS production in roots of YtA and YtB (bar represents 100 μm). Production of ROS was quantified after compiling the projections from 23 confocal sections of 0.74 μm each. R.U, relative unit. The data are given as mean ± SE(n = 3). C The effect of exogenous supply of ROS scavengers. 5-day-old YtA seedling root and 5-day-old YtA seedling root treated with 100 nM VitaminC. D Length of the primary roots of 3-day-old seedlings assay in the absence or in the presence of VitaminC. The data are given as mean ± SE (n = 3).
