Fig 2. Gene expression patterns of VRN-1 and WFT in ‘Chogokuwase’ and its parental cultivars.

Expression levels were measured in the second (2L), third (3L) and fourth (4L) leaf stages of ‘Chogokuwase’ (blue), ‘Minaminokomugi’ (red), and ‘Geurumil’ (yellow) under V0-LD, V21-LD and V0-SD conditions. X- and Y-axis indicate days after 21 days-vernalization and relative transcript abundances, respectively. Transcript abundance was measured relative to the abundance of Actin gene transcripts. Bars on each observation indicate standard errors.
