The flu mutant of Arabidopsis thaliana overaccumulates in the dark the immediate precursor of chlorophyllide, protochlorophyllide (Pchlide), a potent photosensitizer, that upon illumination generates singlet oxygen (1O2). Once 1O2 has been released in plastids of the flu mutant, mature plants stop growing, while seedlings die. Several suppressor mutations, dubbed singlet oxygen-linked death activator (soldat), were identified that specifically abrogate 1O2-mediated stress responses in young flu seedlings without grossly affecting 1O2-mediated stress responses of mature flu plants. One of the soldat mutations, soldat8, was shown to impair a gene encoding the SIGMA6 factor of the plastid RNA polymerase. Reintroduction of a wild-type copy of t...
