Fig. 4From: Oligo-carrageenan kappa increases glucose, trehalose and TOR-P and subsequently stimulates the expression of genes involved in photosynthesis, and basal and secondary metabolisms in Eucalyptus globulusLevel of transcript encoding proteins involved in photosynthesis in E. globulus treated with OC kappa. Relative level of transcripts encoding subunit A of photosystem II (psbA, a), subunit Rieske of cytochrome b6f (petC, b), plastocyanin (petE, c), subunit F photosystem I (psaF, d) and magnesium chelatase (chlH, e), in control (open circles) and E. globulus trees treated with OC kappa at 1 mg mL− 1 (black circles) Asterisks (*) represent significant differences (p < 0.05) between the level of transcripts at a certain week compared with the expression at the beginning of the experiments (week 0). The level of transcripts is expressed as 2-ΔΔCt. Circles represent mean values of three independent experiments ±SDBack to article page
