RNA from Upland cotton (Gossypium hirsutum) roots under conventional disk or no tillage
16 gossypium hirsutum individuals were randomly selected, 2 each from eight plots. Plots were randomly assigned to either conventional disk tillage (4 plots) or no tillage (4 years), and were either tilled or not tilled for 30 consecutive years. An Illumina TruSeq kit was used to produce single-end libraries.
