Samples harvested after growing them in continuous dark for 8 days (8DD) including germination and followed by 48hrs (48LL) of continuous exposure to light (120µmol/m2/sec at soil surface). The growth chamber was set to cycle between 20C for 12 hours and 18C for the next 12 hours, and the soil was kept moist by gently spraying with water every 72 hours. For continuous dark (no light) regimen samples, sampling was done at 7.30 pm after green light. For samples with 8 days continuous dark followed by 2 days continous light, sampling was done at 10am under light. Continuous light (2-Days): Samples harvested after growing them in continuous dark for 8 days including germination followed by 48hrs (48LL) of continuous exposure to light (120µmol/m2/sec at soil surface). Total RNA from frozen seedling shoot samples was extracted as per manufacturer's protocol for RNA Plant reagent (Invitrogen Inc., USA), RNeasy kits (Qiagen Inc., USA), and RNase-free DNase (Life Technologies Inc., USA).  True-Seq kit (Illumina Inc.) was used to prepare RNA-seq libraries, according to the manufacturer's protocol.
