Phosphorylation of C6‐ and C3‐positions of glucosyl residues in starch is catalysed by distinct dikinases
Glucan, water dikinase (GWD) and phosphoglucan, water dikinase (PWD) are required for normal starch metabolism. We analysed starch phosphorylation in Arabidopsis wild‐type plants and mutants lackingExpand
