TSS sequencing in Red1h, Red3h, cRed light. Arabidopsis thaliana strain:Col-0

Total RNA was extracted from 4-day-old wild-type (WT) and phyAphyB double mutant etiolated seedlings. Etiolated plants were exposed to continuous red light (cR) for 0 h, 1 h, or 3 h. These plants were exposed in red light for short time period. Without any etiolated condition, WT and phyAphyB double mutant seedlings were grown in red light for 4-days.
