gene SUS4, recombinant ectopic expression of the enzyme in Zea mays seed endosperm. Transgenic developing seeds exhibit a significant increase in SuSy activity, the transgenic seeds accumulate 10-15% more starch at the mature stage and contain a higher amylose/amylopectin balance than wild-type maize seeds, while no significant changes are detected in the transgenic seeds in the content of soluble sugars, and in activities of starch metabolism-related enzymes when compared with wild-type seeds, overview | Solanum tuberosum |

additional information | recombinant ectopic expression of the enzyme from Solanum tuberosum in Zea mays seed endosperm leads to transgenic developing seeds that exhibit a significant increase in SuSy activity. The transgenic seeds accumulate 10-15% more starch at the mature stage and contain a higher amylose/amylopectin balance than wild-type maize seeds, while no significant changes are detected in the transgenic seeds in the content of soluble sugars, and in activities of starch metabolism-related enzymes when compared with wild-type seeds, phenotype, overview. Enhancement of the enzyme activity does not affect the redox status of AGP | Zea mays |

physiological function | enhancing sucrose synthase activity results in increased levels of starch and ADP-glucose in maize seed endosperms | Zea mays |
physiological function | sucrose synthase is a major determinant of sink strength that highly controls the channeling of incoming sucrose into starch and cell wall polysaccharides, the enzyme is involved in production of starch and ADP-glucose | Solanum tuberosum |
