Figure 2.

Relative expression of cytokinin biosynthesis (PsIPT), activation (PsLOG) degradation (PsCKX) and response regulator (PsRR) gene family members along with PsSWEET, PsSUT, PsCWINV and PsAAP gene family members in Pisum sativum cotyledons at two days post-imbibition (dpi), and in cotyledons, shoots and roots at 5, 9 and 15 dpi. Values are fold-changes relative to the expression at four hours post-imbibition (4 hpi). The colour scale indicates up-regulated expression (red scale), similar (white) and down-regulated expression (blue scale) relative to 4 hpi.
