Col-LowR/FR-rep2 (CRX1817507; CRA027209)
Seedlings were grown in WL for 5 d, then either kept in WL or transferred to low R/FR for 1 h respectively.  Seedlings were collected and total RNA was extracted from snap-frozen tissues using FastPure Cell/Tissue Total RNA Isolation Kit V2 (RC112;Vazyme) according to the manufacturer's instructions. RNA libraries were constructed using NEBNext Ultra RNA Library Prep Kit for Illumina (E7530L; NEB), and then sequenced on a NovaSeq 6000 platform to generate paired-end 150bp reads.
