Starch leaves

The GBSS in leaves can be differentiated from those observed in storage tissue. As has been shown, the amylose content of starch can vary from 11% to 37% in storage tissue.203 In leaf or transistory starch, the amylose content is less than 15%. In pea, leaf starch amylose has a greater molecular weight than does storage starch... 

Incubation of spinach leaf starch granules with extrachloroplastic phosphorylase resulted in the formation of glucose 1-phosphate (Steup et al., 1983). Hammond and Preiss (1983) reported a large increase in cytosolic phosphorylase from spinach leaf in a time course that approximates the time of leaf senescence (i.e., when starch chloroplast must be hydrolyzed and exported to active sinks).
