Effect of submergence on the level of β-1,3 : 1,4-glucan in tissues

	Amount in tissues (mg g−1 f. wt)*	Relative amount (%)†
Initial	1·51 ± 0·11	100·0
Control	1·49 ± 0·02	98·7
Submergence‡	1·11 ± 0·05	73·5

* β-1,3 : 1,4-glucan extracted from rice seedlings was degraded into β-1,3 : 1,4-glucan-specific oligosaccharides. The level of β-1,3 : 1,4-glucan was determined based on the amount of the oligosaccharides using an HPAEC-PAD system. Data are means ± s.e. of triplicate assays.

^† Relative amounts are expressed as a percentage of that of initial seedlings.

^‡ Rice seedlings were grown for 12 h under water.
