miR160, miR167, and miR171 are involved in development of root system under N starvation coditions.

<p>(A) More lateral roots in 35S::miR160a plants than WT (wild-type) plants. (B) Expression of miR160, miR167, miR171, and their targets under N starvation conditions. Gene expression values shown are relative to the expression in plants grown under normal MS medium, for which the value is set to 1. Error bars indicate ± SE obtained from three biological repeats. Values marked by an asterisk are significantly different from the corresponding control value with Student's <i>t</i>-test (<i>p</i><0.01; <i>n</i> = 3). (C) A putative work model for miRNA-mediated root growth under N starvation conditions.
