- Publication
- Mutation of the plastidial alpha-glucan phosphorylase gene in rice affects the synthesis and structure of starch in the endosperm, 2008, Plant Cell.
- 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.
- Genbank accession number
- Key message
- The loss of Pho1 caused smaller starch granules to accumulate and modified the amylopectin structure
- These results strongly suggest that Pho1 plays a crucial role in starch biosynthesis in rice endosperm at low temperatures and that one or more other factors can complement the function of Pho1 at high temperatures
- The phenotype of the pho1 mutation was temperature dependent
- Plastidial phosphorylase (Pho1) accounts for approximately 96% of the total phosphorylase activity in developing rice (Oryza sativa) seeds
- Variation in the morphological and biochemical phenotype of individual seeds was common to all 15 pho1-independent homozygous mutant lines studied, indicating that this phenotype was caused solely by the genetic defect
