RNA was extracted from 0.1 g of each sample using a Qiagen RNeasy Mini Kit, and checked for quality using a Thermo Scientific NanoDrop™ One/OneC Microvolume UV-Vis Spectrophotometer. Libraries were generated with the TruSeq UD V1.5 Kit following the instruction manual. Samples were loaded on the Illumina NovaSeq 6000 platform for pair-end sequencing with 150 cycles at the Omics and Precision Agriculture Laboratory.
