- Publication
- Plastidial Disproportionating Enzyme Participates in Starch Synthesis in Rice Endosperm by Transferring Maltooligosyl Groups from Amylose and Amylopectin to Amylopectin., 2015, Plant Physiol.
- Rice endosperm starch phosphorylase Pho1 assembles with disproportionating enzyme Dpe1 to form a protein complex that enhances synthesis of malto-oligosaccharides., 2016, J Biol Chem.
- Pho1 cooperates with DPE1 to control short maltooligosaccharide mobilization during starch synthesis initiation in rice endosperm., 2023, Theor Appl Genet.
- Genbank accession number
- Key message
- We present here the functional identification of DPE1 in storage starch synthesis in rice (Oryza sativa L
- DPE1 overexpression decreased amylose content and resulted in small and tightly packed starch granules, whereas DPE1 suppression increased amylose content and formed heterogeneous-sized, spherical, and loosely packed starch granules
- Changes in DPE1 gene expression also resulted in modifications in the thermal and pasting features of endosperm starch granules
- These findings demonstrate that DPE1 participates substantially in starch synthesis in rice endosperm by transferring maltooligosyl groups from amylose and amylopectin to amylopectin
- Pho1 cooperates with DPE1 to control short maltooligosaccharide mobilization during starch synthesis initiation in rice endosperm.
- These findings show that Pho1 cooperates with DPE1 to control short MOS mobilization during starch synthesis initiation in rice endosperm
