Fig. 1: CsPGR5a and CsPGR5b are involved in the responses to multiple hormones and abiotic stress.

From: The key cyclic electron flow protein PGR5 associates with cytochrome b6f, and its function is partially influenced by the LHCII state transition

a Main cis-acting elements in the promoters of cucumber PGR5 genes, as predicted by PlantCARE. b–h Expression patterns of the CsPGR5a and CsPGR5b genes in cucumber leaves under different hormone treatments, abiotic stresses and Put treatment. Every morning when the lights were turned on (at 0, 24, 48 h), the leaves were sprayed with 100 μM ABA, 100 μM salicylic acid (SA), 100 μM methyl jasmonate (MeJA) or 8mM Put; treated with 20% polyethylene glycol (PEG) 6000 to mimic drought stress; subjected to 4 °C to induce cold stress; or treated with 100 mM NaCl to induce salt stress. i Relative expression levels of the CsPGR5a and CsPGR5b genes under different light conditions. The label “0” means that the seedlings were fully dark-adapted. The relative gene expression levels were normalized to the level of CsPGR5a at 0h or at 0 light intensity. The different letters indicate significant differences between treatments (P < 0.05) according to Tukey’s test
