GSM4845035: HDX33_ATH_NEC_3: Arabidopsis infected by S. sclerotiorum rep3 [re-analysis]; Sclerotinia sclerotiorum 1980 UF-70; RNA-Seq
The edge and center of developed mycelial colonies (~20 mm diameter) was harvested and stored in liquid nitrogen. Samples were ground with metal beads (2.5 mm) in a Retschmill apparatus (24hertz for 2x1min) before solubilizing in 1mL Trizol reagent (ThermoFisher) and left for 5 min at RT. Chloroform (200 µL) was added and mixed thoroughly before incubating for 3 min at RT. After centrifugation at ~12,000g (4°C) for 15min, the upper aqueous phase was recovered and nucleic acids were precipitated by adding 2µL GlycoBlue (Ambion) and 500µL isopropanol (10 min at -20°C). After centrifugation at ~15,000g (4°C) for 15min, pellets were washed twice with 70% ethanol before drying and resuspended in RNAse-free water. To eliminate chloroform traces, water resuspended nucleic acids were further cleaned using an RNA extraction kit (Quiagen) following manufacturer's instructions. Genomic DNA was removed by DNase treatment (TURBO DNase; Ambion) following manufacturer's instructions. The quality and concentrations of RNAs preparations were assessed with an Agilent apparatus and chips (nano). RNA libraries were prepared for sequencing using standard Illumina protocols
