Plastidial (p)ppGpp synthesis by the Ca2+-dependent RelA-SpoT homolog regulates the adaptation of chloroplast gene expression to darkness in Arabidopsis
S. Ono, S. Suzuki, D. Ito…·S. MASUDA
This study shows that CRSH-dependent (p)ppGpp synthesis in Arabidopsis regulates plastid gene expression adaptation to darkness by transiently increasing ppGpp levels, which is counteracted by RSH1, RSH2, and RSH3.
