Level of up-regulated transcripts encoding: PsbA (open circles) and PsbW (open triangles) of PSII (a), PGR-1A (open squares) of PSI (b) and enzymes GGDPS (open squares), CD (black diamonds), PYS (open triangles), LC (open circles) and PD involved in β-carotene synthesis (c) and enzymes G3PDH (open squares), RP3E (black diamonds, PRK (open triangles) and TK (open circles) of Calvin-Benson cycle (d) in the marine alga Ulva compressa cultivated with 10 μM copper for 0, 3, 6, 12 and 24 h. Level of transcripts is expressed as normalized reads and time in hours
