Pectin-like heteroxylans in the early-diverging charophyte Klebsormidium fluitans.

ABSTRACT:

Background and aims

The cell walls of charophytic algae both resemble and differ from those of land plants. Cell walls in early-diverging charophytes (e.g. Klebsormidiophyceae) are particularly distinctive in ways that might enable survival in environments that are incompatible with land-plant polymers. This study therefore investigates the structure of Klebsormidium polysaccharides.

Methods

The 'pectin' fraction (defined by extractability) of Klebsormidium fluitans, solubilized by various buffers from alcohol-insoluble residues, was digested with several treatments that (partly) hydrolyse land-plant cell-wall polysaccharides. Products were analysed by gel-permeation and thin-layer chromatography.

Key results

The Klebsormidium pectic fraction made up ~30-50 % of its a
