Composition of Aphanomyces and Phytophthora cell walls

Compounds	Composition of cell wall hydrolysatesa in:
	A. euteiches	P. parasitica
Proteinsb	158 ± 52	124 ± 16
Glucosec	714 ± 83	839 ± 112
Mannosec	NDd	17 ± 12
Glucosaminec	107 ± 16	5.2 ± 3.6

^aThe data are means ± SD from four independent experiments and are expressed as μg·mg⁻¹ (dry weight) of crude cell walls.

^bProtein content was calculated from the amount of total nitrogen corrected for the amount of nitrogen brought about by glucosamine.

^cNeutral sugars and glucosamine were quantified by HPAEC-PAD after acid hydrolysis as described in Materials and Methods. Note that N-acetyl-d-glucosamine is converted to glucosamine by the hydrolysis procedure.

^dND, not detected.
