Table 1.

Labeling scheme for 8 gels: the internal standard (IS) and each analyzed sample were labeled with CyDye 2, 3, or 5 as shown in the table. The internal standard is generally the mixture of the same portions of all analyzed samples.

Gel number	CyDye 2	CyDye 3	CyDye 5
1	IS	88”	51∗
2	IS	61∧	52∗
3	IS	54∗	76#
4	IS	55∗	86”
5	IS	77#	62∧
6	IS	89”	64∧
7	IS	63∧	90”
8	IS	80#	78#

∗: control, #: PEG drought stress, ∧: no irrigation drought stress, and ”: salt stress.
