Plastidial Phosphorylase (Pho1a) is the dominant glucosyltransferase regulating starch granule initiation in potato tubers

Starch granule initiation involves the extension of maltooligosaccharide primers by glucosyltransferases.

Starch granule initiation involves the extension of maltooligosaccharide primers by glucosyltransferases. STARCH SYNTHASE 4 (SS4) plays a central role in almost all examined plant species, while the plastidial PHOSPHORYLASE 1 (Pho1) also plays an important role in some species,…
