Figure 4.
Size distribution of subfractions I and II from leaves of wild-type plants and from cPGM-overexpressing (A) and cPGM-underexpressing (B) lines was analyzed by FFF coupled to MALLS-DRI. From each line, three independently prepared SHGL samples were subjected to FFF. A typical elution profile for each line and for the wild type (Wt) is shown. The refractive index (RI) signals (solid lines) and the molar mass distributions obtained by MALLS-DRI (dots) are plotted against the eluate volume. A and B designate the two overexpressing lines, and C and D designate the two underexpressing lines (Table I).
