Fig. 4.

(A) Postcold spliced mRNA relative to nonvernalized (NV) levels from analog (an) and digital models (both classes, d1 and d2), compared with experiments (ex). Uninterrupted cold is compared with (Left) one, (Center) two, and (Right) three interruptions; e.g., 2 × 7 d refers to two periods of 7 d cold duration, with a warm interruption in between, compared with 14 d of uninterrupted cold. Error bars are SEM, with n = 3 (Left) and n = 2 (Center and Right) for experiments and n = 10 for simulations. (B) Leaf number as a measurement of flowering time, for two and three interruption treatments. Box and whisker plots show median, 25th, and 75th percentiles and range of data excluding any outliers, which are represented as individual points; n = 12 for each set of measurements.
