Retrograde signaling and photoprotection in a gun4 mutant of Chlamydomonas reinhardtii.

Molecular plant - 1 Nov 2012

Formighieri Cinzia, Ceol Mauro, Bonente Giulia, Rochaix Jean-David, Bassi Roberto

Abstract excerpt

GUN4 is a regulatory subunit of Mg-chelatase involved in the control of tetrapyrrole synthesis in plants and cyanobacteria. Here, we report the first characterization of a gun4 insertion mutant of the unicellular green alga Chlamydomonas reinhardtii. The mutant contains 50% of chlorophyll as compared to wild-type and accumulates ProtoIX. In contrast to the increase in LHC transcription, the accumulation of most...
