Sugar composition (GalA, galacturonic acid; GlcA, glucuronic acid) from 6-d-old etiolated seedlings (ES) and leaves from 40-d-old plants (L) of the wild type, PGX1^AT, PGX1^OE-1, PGX1^OE-48, pgx1-1, and pgx1-2 genotypes. Sugar amounts are presented as mean percentages ± sd (n = 6). Bold values indicate mutant glycosyl residue compositions that are at least ±15% and are significantly different (P < 0.05, t test) compared to the wild type for at least two overexpression and/or for both mutant lines.
