Root morphology of transgenic TaVSR1‐B Hap4 wheat. (a) PI staining of roots of 2‐week‐old WT and Hap4‐9 transgenic seedlings. The meristematic zone (MZ) is marked by a white line, and the elongation zone (EZ) by a blue line. Red bars, 500 μm. Each image was made by fusing four photographs of the same root. (b) Zone length of MZ, EZ and differentiation zone (DZ); (c) Cell number of MZ, EZ and DZ; (d) Average cell length of MZ, EZ and DZ. At least 10 roots were measured in each of three repeated experiments. Error bars, ± SE. Statistical significance was determined by a two‐sided t‐test, ^* P < 0.05, ^** P < 0.01.
