Root hair morphology of rice seedlings grown in different media with various pH. (A) Root hairs of three-day-old seedlings of wild-type (WT) and srh2 grow on Murashige and Skoog medium at pH 4.5 and 6.0. Bar=1mm. (B) The root hairs of the WT and srh2 examined under a microscope (pH 4.5). Bar=100 μm. (C) Cross section of root tip from WT and srh2 seedlings grown at pH 4.5. The section was strained with toluidine blue (TBO). Bar=20 μm. (This figure is available in colour at JXB online.)
