Cell wall composition of wild-type and cyt1 embryos

	Wild-type	cyt1-1
Average dry weight	2.6 μg/embryo	1.0 μg/embryo
Neutral sugars	61 μg/mg*	64 μg/mg*
Rhamnose	5.2% (0.30)	7.9% (1.3)
Fucose	2.0% (0.16)	0.9% (0.07)
Arabinose	54.9% (1.1)	53.0% (1.4)
Xylose	19.5% (1.1)	23.5% (1.7)
Mannose	4.8% (0.32)	1.7% (0.21)
Galactose	13.6% (1.7)	13.0% (1.3)
Cellulose	31 μg/mg (0.6)	5.9 μg/mg (0.8)

The total amount of neutral sugars of the noncellulosic wall and the amount of cellulose are expressed as a fraction of the dry weight. Values for individual neutral sugars indicate their relative weight with respect to all six sugars analyzed. Average of three measurements, about 500 cyt1-1 embryos or 200 wild-type embryos per sample, standard deviation in brackets.
