Fig 5. Regulation of StBBX family genes expression during etiolation and de-etiolation.

Analysis of StBBX transcript abundances in 2-week-old phytotron-grown S. tuberosum plants under a 14-h photoperiod—control plants (solid blue line) and a continuous dark followed by a 14-h photoperiod (black bold line). Samples were collected at the indicated time points. qRT-PCR was performed as described in Material and Methods.
