dc.description.abstract
Soil is a crucial component of the biosphere and is a major sink for organic
carbon. Plant roots are known to release a wide range of carbon-based
compounds into soils, including polysaccharides, but the functions of these
are not known in detail. Using a monoclonal antibody to plant cell wall
xyloglucan, we show that this polysaccharide is secreted by a wide range of
angiosperm roots, and relatively abundantly by grasses. It is also released
from the rhizoids of liverworts, the earliest diverging lineage of land
plants. Using analysis of water-stable aggregate size, dry dispersion particle
analysis and scanning electron microscopy, we show that xyloglucan is
effective in increasing soil particle aggregation, a key factor in the
formation and function of healthy soils. To study the possible roles of
xyloglucan in the formation of soils, we analysed the xyloglucan contents of
mineral soils of known age exposed upon the retreat of glaciers. These glacial
forefield soils had significantly higher xyloglucan contents than detected in
a UK grassland soil. We propose that xyloglucan released from plant
rhizoids/roots is an effective soil particle aggregator and may, in this role,
have been important in the initial colonization of land.
