Gene expression three weeks after sowing. X-axis represent the successive sowings, from 11th February until 8th April. Unvernalized plants (sowings 1 to 9) and vernalized control (V) of ‘Hispanic’ (blue) and ‘Barberousse’ (yellow) are plotted. Mean of 3 biological replicates. Error bars are SEM. ND, Not detected. HvFT1 expression is not reported as it was null for all non-vernalized samples. For each NV time-point, bars with the same letter are not significantly different at P < 0.05 according to ANOVA that included genotypes and all sampling times
