Frozen soil samples were handled on dry ice during aliquoting/transfer to extraction tubes. For each sample, RNA was extracted from 2 g soil using the PowerSoil RNA isolation kit (Qiagen, CA, USA). The extracted RNA was treated with Turbo DNase (Invitrogen, Waltham, MA, USA) followed by clean up with a Zymo RNA Clean and Concentrator Kit purification kit (Zymo Research, Irvine, CA, USA).
