Effects of ZmNAC1 overexpression on lateral root development. Wild-type Columbia ecotype (Col) and transgenic seedlings overexpressing 35S-ZmNAC1 were grown on MS medium with 3% sucrose. Plants were photographed 11 d after germination. The numbers of lateral roots per centimeter of primary root of each seedling (average±SE) for wild type Col and 35S-ZmNAC1 are presented at the bottom (n=18). It can be clearly observed on the vertically oriented plates that the transgenic plants had many more lateral roots than the wild type.
