library_construction_protocol: For total RNA extraction, we followed the protocol as described in the RNAprep Pure Plant Kit (TIANGEN, Beijing, China). Sequencing libraries were generated using NEBNext UltraTM RNA Library Prep Kit for Illumina (NEB, USA) following manufacturer's recommendations and index codes were added to attribute sequences to each sample.
