Phenotypic characterization of an Arabidopsis stn7 stn8 pck2 triple mutant reveals only minor effects on chloroplast functions
Reversible protein phosphorylation is a key regulator of chloroplast function. Although chloroplast kinases STN7, STN8, and plastid casein kinase 2 (pCK2) regulate photosynthetic acclimation and other chloroplast processes, their functional interplay remains poorly understood. We generated and characterized the first Arabidopsis thaliana stn7 stn8 pck2 triple knockout mutant. Biochemical analyses…
