Is the glucose exudates?


Partially.

Biochemical analyses confirm that fractions enriched in root cap
mucilage contain very high levels of fucose and galactose, high levels
of arabinose, xylose and glucose and trace amounts of mannose. Fractions
enriched in rhizodermal mucilage contain large amounts of glucose,
moderate amounts of arabinose, xylose, mannose and galactose and trace
levels of fucose. Isoelectric focusing and SDS-PAGE indicate that there
are numerous similarities in the protein composition of materials
enriched in root cap mucilages from root exudates or aqueous root
surface extracts.
