  1. Fold-change values of Pro-Ca-treated vs. water-treated (control) runner tips at 2 (P2/C2) and 4 days (P4/C4) after treatment, and SD- vs. LD-grown axillary buds before (SD/LD6) and after (SD/LD10) the determination of bud fate are shown. UBI14 or UBI14 + Rubisco small subunit 1a were used as control genes in bud samples and runner tip samples, respectively. Values are means of two biological and three technical replicates.
