Changes in miRNA levels upon cold treatment. Plants of three maize inbred lines were grown at 24 °C/22 °C (control, day 0) and transferred to 14 °C/12 °C for seven days. Third leaves were collected at time points indicated, total RNA was isolated and individual miRNA species were quantitated as described in Materials and Methods. Data are means ± SD for three independent experiments with three plants each
