seedling the CHLH gene encoding the H subunit of Mg-chelatase is induced by continuous white, red, far-red or blue light with an initial peak after 2–4 h light. Mg-chelatase subunit genes CHLI and CHLD and the ferrochelatase genes FC1 and FC2 are not strongly regulated at the level of transcript abundance, but the Mg-chelatase regulator GUN4 has an expression profile almost identical to that observed for CHLH. Transcription of both CHLH and GUN4 is primarily under the control of phytochromes A and B and compromised in the phytochrome-signalling mutants fhy1 and fhy3 Arabidopsis thaliana
