Sucrose synthase

Sucrose synthase promotes starch synthesis and accumulation in maize endosperm and potato tubers; overexpression of this enzyme increases starch and glucose contents in potato tubers, while inhibition of its activity reduces starch contents in maize seeds and potato tubers^[1][2].
Sucrose synthase activity promotes cotton fiber development/elongation, and increases cellulose content and xylem cell wall thickness in tobacco^[1].
Sucrose synthase activity enhances the waterlogging stress tolerance of cucumber and barley plants^[1].
Sucrose synthase catalyzes the reversible cleavage/synthesis of sucrose, and its activity preference is pH-dependent; its function requires specific GT-B domain residues, and it is regulated by phosphorylation and trehalose 6-phosphate^[2].
Sucrose synthase located in phloem is essential for callose deposition in Arabidopsis thaliana. Root-expressed sucrose synthase (AtSUS1, AtSUS4) improves submergence tolerance; overexpression of sucrose synthase accelerates plant growth, raises biomass accumulation and triggers early flowering, and induces dichotomous branching via boosting meristematic cell proliferation^[2].
Sucrose synthase overexpression elevates wood cellulose content, cell wall thickness and wood density in Populus species and facilitates total carbon deposition into wood cell walls; heterologous expression of poplar xylem sucrose synthase in tobacco raises cellulose content and xylem cell wall thickness^[2].
Sucrose synthase promotes seed weight gain and starch accumulation in pea embryos; despite normal nodule development and normal nitrogenase protein levels, this enzyme is essential for nitrogen fixation in nodules^[2].
