title: RNA-seq of maize root tissues and cell types in response to cold stress
design: Seeds of the maize genotype 'PE0075' were grown in paper rolls soaked with ddH2O for four days under control conditions. Four days after germination in paper rolls under control conditions (26 C/18 C for 16 h light/8 h dark), seedlings were subsequently subjected to control or cold treatment randomly without preselection (16 C /12 C for 16 h light/8 h dark). The first sampling (time point 1) was carried out after 16 h of growth at 26 C (control) or 16 C (cold) simulating growth during the day. The second sampling (time point 2) was carried out after another 8 h of growth under 18 C (control) simulating growth at night.  RNA were isolated from induvidual samples and sent for library preparation and sequencing
