Fig. 5

Heatmap representing the relative transcript abundance of differentially expressed antioxidant enzyme-encoding genes, strigolactone Signaling genes, and sucrose metabolism enzyme genes in the leaves and roots of cucumber seedlings under low light stress with or without GR24 treatment. Note: The gene expression intensity is represented with a colour gradient from blue (low) to red (high). The respective parameters were measured at 7 days after the start of low light stress and/or 10 μM GR24 treatments. Cont, 0 μM GR24 + 500 μmolm^− 2 s^− 1 PPFD; Cont+GR24, 10 μM GR24 + 500 μmolm^− 2 s^− 1 PPFD; LL, 0 μM GR24 + 60 μmolm^− 2 s^− 1 PPFD; LL + GR24, 10 μM GR24 + 60 μmolm^− 2 s^− 1 PPFD. Here, MDHAR R, monnodehydroascorbate in roots; MDHAR L, monnodehydroascorbate in leaves; DHAR R, dehydroascorbate reductase in roots; DHAR L, dehydroascorbate reductase in leaves; GR R, glutathione reductase in roots; GR L, glutathione reductase in leaves; APX R, ascorbate peroxidase in roots; APX L, ascorbate peroxidase in leaves; MAX₂ R, more axillary growth 2 in roots; MAX₂ L, more axillary growth 2 in leaves; SPS L, sucrose phosphate synthase in leaves; SS L, sucrose synthase in leaves
