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.
