light condition
Total RNA for the RNA-seq analysis was extracted from leaves of  WT and oss40-14 plants incubated in complete darkness for 3 days. One biological replicate from oss40-14.1 independent mutant  and another two replicates were performed from oss40-14.2 independent mutant for RNA seq analysis as both mutants exhibit a dark-induced phenotype. RNA-Seq was performed with an Illumina HiSeqX instrument (Illumina. San Diego, CA, USA).
