physiological function | isoform Sus2 knockout mutant shows 30-50% less sucrose synthase activity than wild-type and therefore accumulates 40% more sucrose and 50% less fructose at 15 days after flowering. Mutation does not affect the hexose phosphate pool, but leads to 30-70% less starch in embryo and seed coat. Lipid content is are 55% higher at 9-15 days after flowering. Final seed size and composition are unaltered due to an earlier cessation of growth, thus giving rise to an apparent silent phenotype of mature mutant seeds | Arabidopsis thaliana |
