Figure 5.

Polysaccharide Compositions of Cell Walls Isolated from Leaves of PVX-Infected Plants.

The major differences in polysaccharide compositions are the decreased cellulose and increased homogalacturonan contents of walls from the PVX–NtCesA-1a and PVX–NtCesA-1b plants. A small increase in galactoglucomannan is apparent in walls from the PVX–NtCesA-2 leaves. Specific polysaccharide content was determined as described in Methods from data in Table 2. Error bars show standard errors. RGI, rhamnogalacturonan I.
