General Information

EC Number General Information Comment Organism
2.7.1.35 malfunction root growth of a sos4 mutant is significantly decreased when grown on either 100 mM or 200 mM sucrose as compared to root growth on10 mM sucrose. The sos4 mutant plant accumulates phytoglycogen Arabidopsis thaliana
