Table 1. Quantification of plant hormones in wild-type Arabidopsis seedlings.

	Hormones	First test (600 seedlings)		Second test (1200 seedlings)
Organs	(ng/g DW)	free	1 µM IAA	free	1 µM IAA
Shoots	CS	1.93	1.92	1.96	2.10
	BL	nd	nd	nd	nd
	IAA	200	249	96.2	101
Roots	CS	nd	nd	<0.305*	<0.229*
	BL	nd	nd	nd	nd
	IAA	291	377	264	357

*The maximum value is shown as for CS in roots (refer to Materials and Methods for detail). DW, dry weight. nd, not detected.
