Table III. GalA content and Rha-Xyl molar ratio of seed mucilage extracted from mum5-1, mum5-2, and mum5-3 compared with the wild type.

Intact seeds were extracted sequentially with water and RGase. Values (mg g⁻¹ intact dry seeds for GalA and molar ratio for Rha/Xyl ± sd) are shown for three biological repeats.

mum5-1	15.48 ± 0.575	2.66 ± 0.003	31.2 ± 0.27
Wild-type Col-0	13.91 ± 0.441	6.24 ± 0.031	16.1 ± 0.30
mum5-2	16.24 ± 0.332	2.55 ± 0.008	38.1 ± 1.35
mum5-3	14.31 ± 0.769	2.66 ± 0.005	44.3 ± 1.73
