Cell-specific expression of Mkt1. In situ hybridization of Mkt1 with a probe derived from a conserved region (nucleotides 980–1,410, corresponding with amino acids 327–470; see Fig. 1). A, Unstressed root tip; C, stressed root tip (500 mm NaCl, 3 d); E, unstressed plant, vascular tissue in the primary leaf; G, stressed plant, vascular tissue in the primary leaf. B, D, F, and H are tissue sections from the same plants as those in the other panels probed with sense RNA. Bars represent 40 μm.
